Hyper‑Personalized Financial Advice with Agentic AI in Banking (POC)

 

Introduction

This is a proof of concept (POC) I am exploring for potential application in the banking sector. The concept integrates Generative AI for natural‑language financial guidance with Agentic AI (autonomous systems) that continuously optimize recommendations based on customer behavior, market signals, and compliance rules.

Technical Architecture

1. Data Layer

  • Customer Profile: demographics, income, product holdings, risk scores.

  • Behavioral Signals: transaction sequences, spending categories, channel usage.

  • Market Context: interest rates, inflation, asset performance.

  • Feedback Loop: customer acceptance/rejection, click‑through rates, portfolio outcomes.

2. Representation Layer

  • Embeddings:

    • Customer vector ec

    • Product vector ep

    • Context vector ex

  • Fusion: Concatenate or use attention mechanisms to form state representation st=f(ec,ep,ex).

3. Policy Layer (Agentic AI)

  • Contextual Bandits / Reinforcement Learning:

    • Action space: {recommend saving, recommend investment, recommend debt repayment}.

    • Reward function: balances personalization, risk alignment, and compliance.

    • Agent loop: observe state st, choose action at, receive reward rt, update policy.

4. Generative Advisor Layer

  • LLM Integration: Converts structured recommendation into human‑like, compliant advice.

  • Example: Action = “invest 10% in low‑risk fund” → Output = “Based on your current savings and spending, we recommend allocating 10% of your monthly income into a low‑risk investment fund.”

5. Governance Layer

  • Rule Engine: Filters actions by KYC/AML, product eligibility, and risk suitability.

  • Audit Trail: Logs every recommendation and its rationale for compliance review.


Python Example (POC Algorithm)

import numpy as np
import random

# Simplified state: [risk_score, savings_balance, spending_pattern]
states = [
    (0.2, 5000, "high"), 
    (0.7, 20000, "moderate"), 
    (0.9, 100000, "low")
]

actions = ["save_more", "invest", "repay_debt"]

def reward(state, action):
    risk, balance, spending = state
    if action == "invest" and risk < 0.5:
        return -1  # too risky
    if action == "save_more" and balance > 50000:
        return -0.5  # diminishing returns
    return 1  # acceptable advice

# Agentic loop (POC)
for state in states:
    action = random.choice(actions)
    r = reward(state, action)
    print(f"State={state}, Action={action}, Reward={r}")

👉 In production, this would be replaced with a reinforcement learning agent (e.g., Deep Q‑Learning or contextual bandits) connected to a Generative AI layer for natural‑language output.

Technical Project Management Advice

If this POC were developed into a full banking solution:

  • Stakeholder Alignment: Involve compliance, risk, IT security, and CX teams early.

  • Hybrid Methodology: Agile sprints for model iteration + governance checkpoints for regulatory validation.

  • Vendor Coordination: Banking AI often requires multi‑vendor integration (cloud, AI platforms, compliance tools).

  • Data Privacy: Embed GDPR, local banking regulations, and ethical AI guidelines into requirements.

  • Pilot Strategy: Start with a narrow use case (e.g., savings advice for young professionals), measure KPIs, then scale.

  • Fallback Mechanisms: If AI advice fails compliance checks, default to human advisor review.

  • Monitoring: Continuous model drift detection, fairness audits, and explainability dashboards.


Conclusion

This POC demonstrates how Generative AI + Agentic AI could reshape financial advice in banking. The technical foundation—embeddings, reinforcement learning, generative language models, and governance layers—is feasible. Success depends on project management discipline, regulatory guardrails, and customer trust.

Accelerating GenAI in Healthcare: Model Inference Caching at MedicLabs

 In my earlier post, Building a GenAI Medical Assistant/Advisor, I shared how generative AI can reshape patient interactions and medical decision support. While designing that system at MedicLabs, one challenge quickly became clear: raw AI power is impressive, but without speed and responsiveness, users lose trust.

The solution I implemented was Model Inference Caching — a methodology that transformed performance, reduced costs, and made the GenAI assistant practical for real-world healthcare.

Why Model Inference Caching Matters

Generative AI models are resource-intensive. Each inference — whether explaining lab results, summarizing patient records, or advising on treatment protocols — can consume significant compute power. Without optimization, response times lag, frustrating both patients and doctors.

Model inference caching solved this by:

  • Reducing latency: Common queries (like routine lab interpretations) were cached, delivering instant answers.

  • Lowering costs: Avoiding repeated inference runs saved GPU cycles and infrastructure expenses.

  • Improving reliability: Cached outputs acted as a fallback when compute resources were under strain.

How I Applied Caching in MedicLabs

I designed caching to operate primarily on the admin side, ensuring that end-users always experienced top speed while administrators handled the heavier lifting.

Key strategies included:

  • JSON Caching for AI outputs: Structured responses from the GenAI model were stored and reused when identical or similar queries appeared.

  • Inference Embedding Caching: Embeddings for common medical terms and queries were cached, accelerating similarity searches.

  • Hybrid Admin/User Strategy: Admin-side caching handled heavy lifting, while lightweight HTTP caching improved delivery of static assets.

This layered approach meant that doctors and patients interacting with the MedicLabs assistant received answers in seconds, not minutes.

Best Practices I Learned

Through implementation, I discovered several best practices for model inference caching:

  • Cache intelligently, not blindly: Medical queries can be sensitive. I avoided caching patient-specific data, focusing instead on general medical knowledge and frequently repeated queries.

  • Set expiration policies: Medical guidelines evolve. Cached outputs were given TTLs (time-to-live) to ensure accuracy.

  • Balance freshness and speed: Inference caching worked best when paired with monitoring to detect outdated or stale responses.

When to Avoid Caching

Caching isn’t always appropriate. I avoided it in cases such as:

  • Highly personalized queries (unique patient cases) that required fresh inference.

  • Rapidly changing data (like real-time vitals) where accuracy was critical.

  • Sensitive outputs (confidential patient information) that should never be cached.

Caching Meets GenAI

What excites me most is how caching and GenAI complement each other:

  • Predictive Pre-Caching: AI models can anticipate likely queries and pre-cache them.

  • Adaptive Caching: GenAI can decide dynamically whether to serve cached results or trigger fresh inference.

  • Scalable Healthcare AI: With caching, GenAI assistants can serve thousands of patients simultaneously without bottlenecks.

Final Thoughts

Model inference caching was a cornerstone of making the MedicLabs GenAI Medical Assistant practical and scalable. It turned a powerful but resource-intensive system into a responsive, cost-efficient, and trustworthy tool for healthcare.

As I continue exploring AI in healthcare, I see caching not just as a performance hack, but as a strategic enabler of real-world GenAI adoption. By combining caching methodologies with intelligent inference design, we can build systems that are both smart and fast — exactly what modern healthcare demands.

Building a GenAI Medical Assistant/Advisor for Our Family Lab: Lessons from Taking AI into the Real World

Working with Generative AI in enterprise environments is one thing.
Building and shipping it for a real family business, where real people rely on the output, is something else entirely.

At MedicLabs, our medical analysis platform, I wasn’t just managing delivery.
I was also responsible for designing, developing, and integrating the GenAI feature myself.

That changed how I think about GenAI more than any corporate project ever did.


The Problem We Were Trying to Solve

Patients receive blood test results every day.

Most of them:

  • Don’t understand the medical terms

  • Misinterpret values

  • Panic unnecessarily

  • Or, worse, ignore important signals

Doctors are busy.
Lab reports are technical.
And patients are left somewhere in between.

The goal was not to replace doctors.
It was to translate medical data into understandable, responsible guidance — safely.


Designing for Responsibility First

From the beginning, I treated this as a medical-support system, not a generic AI chatbot.

Key principles guided the design:

  • No diagnosis claims

  • No absolute medical decisions

  • Clear explanations of what values mean

  • Suggestions framed as guidance, not conclusions

  • Strong emphasis on consulting a physician when needed

Trust mattered more than intelligence.


Doing the Development Work Myself

I personally handled:

  • Data structure design for lab results

  • Prompt engineering for medical context

  • Multilingual output handling (Arabic, English, French)

  • Safety constraints and phrasing control

  • Integration into the existing web platform

  • UI flow to avoid overwhelming the patient

This was not a plug-and-play solution.
It required iteration, testing, and constant refinement.

Every small wording change mattered.


What the System Actually Does

When a patient uploads or views blood analysis results, the system:

  • Explains each value in simple language

  • Highlights what is within normal range and what isn’t

  • Provides general lifestyle and health advice

  • Suggests potential follow-up tests based on patterns

  • Clearly states limitations and when to consult a doctor

No fear-based messaging.
No false certainty.


How This Helped Patients

The most immediate impact was clarity.

Patients:

  • Understood their results without panic

  • Felt more confident discussing results with doctors

  • Became more proactive about their health

  • Returned to the platform to track changes over time

Instead of raw numbers, they received context.


How This Helped the Business

From a business perspective, the impact was equally clear.

The AI-driven insights:

  • Increased engagement time on the platform

  • Reduced repetitive inquiries to lab staff

  • Encouraged patients to perform recommended follow-up tests

  • Improved trust in the MedicLabs brand

  • Turned a static report into a living health tool

This was not aggressive upselling.
It was relevant, medically justified guidance.

When done responsibly, value creation benefits both sides.


The Hardest Part Was Not the Technology

The hardest part was balancing:

  • Helpfulness vs safety

  • Clarity vs overconfidence

  • Automation vs responsibility

Every GenAI decision had ethical weight.

This is where being both the developer and the Technical Project Manager mattered.
I could control not just what was built, but how and why.


What This Project Changed for Me

This project reinforced something I strongly believe now:

GenAI is not impressive because it can generate text.
It’s impressive when it:

  • Reduces confusion

  • Improves decision quality

  • Respects domain boundaries

  • And creates sustainable value

Especially in healthcare, responsibility is not optional.


Closing Thought

Building GenAI features for real users — especially in sensitive domains — forces a different level of discipline.

This wasn’t a demo.
It wasn’t a slide deck.
It was a system people actually use.

And doing both the technical implementation and the delivery ownership made one thing very clear to me:

The future of GenAI belongs to teams who can build responsibly, not just quickly.

Managing Hallucinations & Trust in GenAI: What Building Real Systems Taught Me

One of the earliest lessons I learned working with Generative AI is that correctness is not binary.

Unlike traditional systems, GenAI doesn’t simply fail or succeed. It responds — sometimes confidently — even when it’s wrong. And that behavior fundamentally changes how trust must be designed, not assumed.

Hallucinations are not edge cases. They are a structural characteristic of how these models work.


The Problem Is Not That Models Hallucinate

At first, hallucinations are often treated as a model quality issue.

Improve the prompt.
Switch the model.
Add more data.

Those steps help, but they don’t eliminate the problem.

The deeper issue is how hallucinations interact with users and workflows. A wrong answer that looks plausible is more dangerous than a visible failure. Once users stop trusting the system, no accuracy metric can bring that trust back.


Trust Is a Delivery Concern, Not a Model Feature

I’ve seen projects where technically strong models failed in production because trust was never explicitly managed.

Trust is shaped by:

  • How confident responses sound

  • Whether uncertainty is communicated

  • How errors are handled

  • What happens when the model doesn’t know

None of these are purely data science problems.
They are design and delivery decisions.

As a Technical Project Manager, ignoring trust means risking adoption — even if the model is statistically strong.


How Hallucinations Actually Create Cost and Risk

Hallucinations don’t just affect quality. They create downstream consequences:

  • Incorrect decisions

  • Manual verification work

  • Repeated prompts and retries

  • Escalations and overrides

  • Loss of confidence in AI-assisted workflows

In regulated environments, the impact is even larger:

  • Compliance exposure

  • Audit challenges

  • Reputation damage

Trust issues compound silently until someone decides the system is “not reliable” and stops using it.


The Shift: From Preventing Hallucinations to Managing Them

At some point, the mindset has to change.

The goal is not zero hallucinations — that’s unrealistic.
The goal is controlled behavior when hallucinations occur.

That means designing systems that:

  • Know when confidence is low

  • Surface uncertainty instead of hiding it

  • Fall back to safer paths

  • Involve humans when risk crosses a threshold

This is an architectural choice, not a last-minute fix.


What Has Worked in Practice

In real projects, trust improved when we focused on a few principles:

  • Constraining models to verified sources when accuracy mattered

  • Separating creative use cases from factual ones

  • Using confidence signals to trigger review

  • Designing “I don’t know” as an acceptable outcome

  • Measuring user trust, not just model accuracy

Interestingly, users were more forgiving of systems that admitted uncertainty than systems that sounded confident and wrong.


Why Hallucinations Change the Role of the Project Manager

GenAI projects blur the line between engineering, product, and risk management.

Managing hallucinations means:

  • Aligning stakeholders on acceptable risk

  • Defining where automation ends

  • Setting expectations early

  • Making trade-offs explicit

This requires active ownership throughout the lifecycle, not just during delivery.


A Different Definition of Success

Success in GenAI is not about eliminating errors.

It’s about creating systems that:

  • Fail safely

  • Protect decision quality

  • Preserve user confidence

  • Improve over time

Trust is not a feature you add at the end.
It’s something you design from the first architecture discussion.


Closing Thought

The most dangerous AI systems are not the inaccurate ones.

They are the ones that sound certain when they shouldn’t.

Managing hallucinations is ultimately about managing trust — and trust, once lost, is extremely hard to regain. For me, that has become one of the most important lessons in delivering GenAI responsibly.

AI Cost Management & FinOps for LLMs: A Reality Check from the Field

When I first started working on Generative AI initiatives, cost was not the primary concern.

Like many teams, we were focused on proving capability:
Can the model understand our data?
Can it generate usable outputs?
Can we integrate it into real workflows?

The early demos were impressive. The costs looked manageable. Everything worked — at least on the surface.

Things changed the moment these systems moved closer to production.


When LLMs Meet Real Usage

LLMs behave very differently from traditional software systems.

Costs don’t scale linearly with users or infrastructure. They scale with:

  • Prompt length

  • Context size

  • Model choice

  • Retry behavior

  • Error handling

  • User behavior

A small architectural decision — an extra paragraph of context, an unnecessary retry, a default model choice — can multiply costs without anyone noticing immediately.

By the time it becomes visible, the budget damage is already done.


Why This Is Not a Finance Problem

One of the biggest misconceptions I see is treating GenAI cost as a finance or procurement issue.

In reality, cost is driven almost entirely by technical and delivery decisions:

  • Which model is used for which task

  • How prompts are designed

  • How often calls are made

  • How errors and hallucinations are handled

  • How results are cached or reused

As a Technical Project Manager, ignoring this means losing control of delivery.
Owning it means enabling sustainable scale.


The Cost Traps I’ve Seen Repeatedly

Across different teams and projects, the same patterns show up:

Overpowered defaults
High-end models are used everywhere “just in case”, even when simpler models would deliver acceptable results.

Prompt inflation
Prompts grow over time as edge cases are added, without revisiting their cost impact.

Invisible retries
Failures and hallucinations trigger silent retries, compounding cost with every error.

No guardrails
No budgets per feature, no alerts, no clear ownership of usage.

None of these are malicious.
They are natural outcomes of moving fast without cost being a first-class concern.


What FinOps for LLMs Actually Means in Practice

For me, FinOps in AI is not about cutting costs aggressively.

It’s about making trade-offs explicit.

Every GenAI system makes implicit decisions about:

  • Accuracy vs cost

  • Speed vs depth

  • Automation vs human review

FinOps forces those decisions into the open and ties them to real business outcomes.

Once cost is visible, better engineering decisions naturally follow.


What Has Worked in Real Projects

In practice, sustainable AI delivery comes from a few disciplined habits:

  • Comparing multiple models for the same use case

  • Matching model capability to business criticality

  • Monitoring cost per request and cost per outcome

  • Treating hallucinations as both quality and cost issues

  • Designing graceful degradation instead of all-or-nothing behavior

The key shift is simple but powerful:
Cost becomes a delivery metric, not a surprise.


A Shift in How I Think About AI Projects

Traditional projects end when features are delivered.

AI projects don’t.
They continue to consume value — or cost — every day they run.

That changes the role of a Technical Project Manager:

  • From delivery-focused to lifecycle-focused

  • From feature tracking to outcome tracking

  • From technical coordination to economic stewardship

This is not theoretical. It’s operational reality.


Closing Thought

The most impressive AI systems are not the most expensive ones.

They are the ones that:

  • Deliver consistent value

  • Earn trust

  • Scale responsibly

  • And remain economically viable over time

AI Cost Management and FinOps for LLMs are not optional add-ons anymore.
They are part of what it means to run AI projects professionally.

AI-Enabled Risk Scoring for TPPs in Open Banking: A Game Changer for Ecosystem Trust

As Open Banking ecosystems mature globally, traditional banks, fintech startups, and regulators face a growing challenge: how to trust the growing number of Third Party Providers (TPPs) that are now gaining access to customer data and payment rails via APIs. In this fast-evolving environment, AI-enabled risk scoring emerges as a powerful tool that can continuously evaluate the trustworthiness of TPPs based on dynamic behavior, financial performance, and regulatory compliance signals.

This article explores what AI-enabled TPP risk scoring is, why it matters, and how it can be practically implemented—both from a strategic and technical lens.


Why TPP Risk Scoring Is Critical in Open Banking

Open Banking regulations like PSD2 in Europe, OBIE in the UK, and similar frameworks across Africa and Asia mandate that banks open up their customer data (with consent) to licensed TPPs. These TPPs include:

  • Payment Initiation Service Providers (PISPs)

  • Account Information Service Providers (AISPs)

  • Aggregators, budgeting apps, and more

While this enhances competition and innovation, it increases the risk landscape:

  • API misuse or abuse

  • Poor data handling practices

  • Operational failures or security gaps

  • TPPs going out of business unexpectedly

Banks must assess “Who are we opening our APIs to?” on an ongoing basis, not just at onboarding. Static checklists aren’t enough.


Enter AI-Powered Dynamic Risk Scoring

An AI-enabled TPP risk scoring system continuously evaluates TPPs based on:

  1. Usage patterns: API request frequency, data volume, error rates.

  2. Behavioral anomalies: Sudden surges, unusual endpoints, suspicious transaction types.

  3. External signals: Regulatory fines, media sentiment, funding rounds, business health.

  4. Peer benchmarking: Comparing a TPP’s activity against industry norms.

  5. Historical incident data: Security breaches, customer complaints, etc.

AI models can assign dynamic risk scores that are updated in real time or on scheduled cycles, making it easier for banks to:

  • Auto-trigger red flags and throttling

  • Prioritize monitoring

  • Optimize SLAs or commercial terms


A Simple Python Example: Behavior-Based TPP Risk Score

Below is a basic Python sketch that uses a decision tree classifier to assess the risk score of a TPP based on its recent API activity profile:

#python

<?XML:NAMESPACE PREFIX = "[default] http://www.w3.org/2000/svg" NS = "http://www.w3.org/2000/svg" />CopyEdit

import pandas as pd from sklearn.tree import DecisionTreeClassifier # Sample dataset data = pd.DataFrame({ 'api_calls_per_day': [1000, 5000, 100, 8000, 300], 'error_rate': [0.01, 0.15, 0.03, 0.25, 0.02], 'sudden_spike': [0, 1, 0, 1, 0], 'past_incidents': [0, 2, 0, 3, 1], 'risk_label': ['low', 'high', 'low', 'high', 'medium'] }) # Convert labels to numeric data['risk_label'] = data['risk_label'].map({'low': 0, 'medium': 1, 'high': 2}) # Train model features = data[['api_calls_per_day', 'error_rate', 'sudden_spike', 'past_incidents']] labels = data['risk_label'] clf = DecisionTreeClassifier(max_depth=3) clf.fit(features, labels) # Predict a new TPP new_tpp = pd.DataFrame({ 'api_calls_per_day': [4500], 'error_rate': [0.18], 'sudden_spike': [1], 'past_incidents': [1] }) predicted_risk = clf.predict(new_tpp)[0] risk_level_map = {0: "Low", 1: "Medium", 2: "High"} print("Predicted Risk Level:", risk_level_map[predicted_risk])

This is a simplified model. Real implementations might involve:

  • Gradient Boosting models or Neural Networks

  • Integration with anomaly detection (e.g. Isolation Forests)

  • Stream processing for real-time scoring (using Kafka or Spark)


Challenges and Considerations

Area
Challenge
Recommendation

Data Privacy
Risk of scoring based on sensitive info
Use anonymized or non-PII behavioral features

Fairness
Biased models could unfairly penalize new TPPs
Ensure transparency and use Explainable AI (XAI)

Regulatory Risk
Compliance with GDPR, PSD2, local rules
Document models, consent sources, scoring logic

Interpretability
Business teams need understandable outputs
Use SHAP values or decision paths


Business Value
  • Enhanced Security: Detect rogue or compromised TPPs early

  • Regulatory Compliance: Proactive risk posture appreciated by auditors

  • Better SLAs: Dynamic risk-based access tiers

  • Ecosystem Trust: Encourage responsible innovation by rewarding good actors


Conclusion

In the Open Banking world, where trust is the currency, AI-enabled TPP risk scoring is no longer optional—it's foundational. Banks and regulators must embrace AI not just for fraud detection, but for proactive partner risk management across the API economy. The path forward involves blending behavioral science, machine learning, and regulatory foresight to make Open Banking safer and smarter for everyone.

Emergency Passwords: A Simple Yet Powerful Shield for Open Banking Security

In a world where open banking is reshaping how we interact with financial institutions, cybersecurity has never been more critical. While the benefits of open banking are clear—seamless integrations, smarter financial management, and personalized experiences—it also opens up a Pandora’s box of cyber threats. One of the most innovative ideas emerging to counter this is the “Emergency Password.”

This concept, although simple, can be a game-changer in protecting user accounts during high-risk situations, especially under duress or when facing social engineering attacks.


What is an Emergency Password?

Imagine you're coerced—either digitally or physically—into logging into your banking app. You can't say no. You can't alert anyone. That’s where the Emergency Password comes in.

An Emergency Password is a secondary, pre-defined credential that looks and feels like a valid login, but when entered:

  • It gives limited access to dummy or decoy data.

  • It silently triggers an alert to the security team.

  • It can optionally freeze high-risk operations like transfers or withdrawals.


How AI Can Detect Emergency Password Usage

AI can play a role in differentiating between a regular login and a duress login based on several features like:

  • Password pattern

  • Device behavior

  • Typing speed

  • Login context (time, location, IP)

Here's a simple Python AI example using scikit-learn to classify a login attempt as normal or under duress:

#python

<?XML:NAMESPACE PREFIX = "[default] http://www.w3.org/2000/svg" NS = "http://www.w3.org/2000/svg" />

 

from sklearn.tree import DecisionTreeClassifier # Sample data: [typing_speed (ms), is_known_device (0/1), is_emergency_password (0/1)] # 0 = normal login, 1 = under duress X = [ [150, 1, 0], # Normal login [140, 1, 0], [400, 1, 1], # Duress (emergency password entered) [380, 0, 1], [160, 0, 0], [390, 1, 1], ] y = [0, 0, 1, 1, 0, 1] clf = DecisionTreeClassifier() clf.fit(X, y) # Incoming login attempt (typing speed: 410ms, known device: yes, emergency password used: yes) login_input = [[410, 1, 1]] prediction = clf.predict(login_input) if prediction[0] == 1: print(" Emergency login detected! Triggering silent alert...") else: print("✅ Normal login.")

What This Code Does:
  • It trains a simple AI model using a few login attributes.

  • When a login is attempted using the emergency password, it flags it as a duress scenario.

  • In a real system, this would trigger silent alerts, activate safe-mode dashboards, or freeze sensitive actions.


Conclusion

In the evolving battlefield of digital finance, traditional passwords are no longer enough. Innovations like the Emergency Password empower users in moments when they are most vulnerable. As open banking continues to grow, so must our creative approaches to security.

Adding this layer of protection isn’t just smart—it’s humane. Because real people, under real pressure, deserve real safety.

How Cyber-Crimes Threaten Open Banking and How to Prevent Them

Open banking is transforming the way businesses and individuals interact with financial institutions, offering increased convenience, faster transactions, and broader access to banking services. However, with this innovation comes the risk of cyber-crimes that can exploit vulnerabilities in these systems. One striking example of how these risks could unfold is a scenario where a criminal, threatening a wealthy individual with a weapon, forces them to transfer funds from their open banking app.

In such a case, the attacker could have full access to the victim's financial information via their mobile device, putting both the individual and financial institutions at risk. As the open banking ecosystem becomes more integrated into everyday life, understanding the technological and business implications of these threats is crucial. Let’s explore how cyber-crimes can negatively affect open banking technologies and the strategies that can be employed to minimize such risks.

Introducing the "Emergency Password"

One innovative way to address physical and psychological threats is by implementing an "Emergency Password". This concept involves allowing users to set a unique password they can use during a high-pressure situation, such as when they are being coerced into transferring money.

Here’s how it works:

  • If a user is under duress and is forced to make a transaction (e.g., at gunpoint), they can enter the "Emergency Password" when prompted for authentication. This password would appear like a normal login but would alert the bank to the situation.

  • Upon entering the emergency password, the transaction would proceed normally, allowing the attacker to think everything is fine. However, the transaction is flagged in the backend as "suspicious," and it is rolled back after a specified period (e.g., 24 hours) unless verified by the user.

  • Simultaneously, the bank would notify local authorities and share the user's GPS location with law enforcement, enabling rapid intervention.

This emergency response could save lives, offering a discreet way for individuals to alert authorities while still complying with the attacker’s demands in the moment. It provides an innovative safeguard for users under physical threat, allowing the system to reverse potentially dangerous transactions and notify the authorities.

1. Vulnerability to Social Engineering and Physical Threats

Open banking technologies heavily rely on the secure exchange of sensitive financial data between banks, third-party providers (TPPs), and consumers. While encryption and authentication protocols help protect this data during transmission, attackers can still exploit human psychology. The scenario where a criminal forces a person to transfer funds at gunpoint is a physical manifestation of social engineering, where an attacker manipulates an individual into giving up access to their banking services.

  • Phishing and SIM-swapping: Cybercriminals may also use less dramatic methods to gain access to accounts, such as phishing attacks or SIM-swapping. These techniques can compromise account credentials, enabling criminals to access banking apps.

2. Mobile Security Risks

As mobile devices become central to open banking, they also become attractive targets for cybercriminals. Open banking apps installed on smartphones often store sensitive credentials, and attackers who gain access to the phone can potentially authorize transactions.

Mobile malware, unauthorized access, or even physical theft of the device can lead to significant financial losses if no additional security measures are in place.

3. Technological Solutions to Reduce Risks

From a technological standpoint, the first line of defense is to ensure that all data exchanges are encrypted using advanced encryption standards (e.g., AES-256). But beyond encryption, here are some essential steps to protect against cyber-crimes:

  • Multi-factor Authentication (MFA): Use multi-factor authentication (MFA) for every transaction or access request. This adds an extra layer of security beyond just the password. For example, integrating biometric features such as fingerprint or facial recognition can ensure that only authorized individuals can access their banking services.

  • Device Management: Financial institutions should implement device management systems that can identify and control the devices accessing their banking apps. This can help mitigate risks from stolen or compromised devices.

  • Transaction Limits and Alerts: For high-value transactions, implement daily or per-transaction limits. Additionally, send instant notifications for every transaction to the user's registered mobile number or email address.

Here’s a simple Python script that demonstrates the concept of alerting users when a high-value transaction attempt is made:

#python

<?XML:NAMESPACE PREFIX = "[default] http://www.w3.org/2000/svg" NS = "http://www.w3.org/2000/svg" />CopierModifier

class Transaction: def __init__(self, amount, transaction_type): self.amount = amount self.transaction_type = transaction_type def alert_user(self): if self.amount > 5000: # Threshold for high-value transactions print(f"ALERT: A transaction of {self.amount} USD is being processed.") print("A notification will be sent to your registered contact.") else: print(f"Transaction of {self.amount} USD processed successfully.") # Simulate a transaction transaction1 = Transaction(10000, "Transfer") transaction1.alert_user()

This simple script checks if a transaction exceeds a predefined threshold and alerts the user about the high-value transaction. By integrating such systems, open banking platforms can add an additional layer of vigilance to prevent unauthorized transfers.

4. Business Solutions to Combat Cyber-crime

From a business perspective, financial institutions should adopt a proactive stance toward cybersecurity. Here are several steps businesses can take:

  • Employee Training: Regularly train employees to recognize potential threats and understand the security procedures for handling sensitive financial data.

  • Collaborate with Law Enforcement: In the event of a physical or online attack, it's essential to collaborate with law enforcement agencies to ensure quick action can be taken to track and apprehend perpetrators.

  • Invest in Cybersecurity Infrastructure: Businesses should invest in robust cybersecurity systems, including firewalls, intrusion detection systems (IDS), and regular security audits.

  • Client Education: Educating clients about safe practices, such as using strong passwords, avoiding suspicious links, and keeping their devices secure, can reduce the likelihood of successful attacks.

5. The Future of Open Banking Security

As the world of open banking evolves, so too will the threats posed by cyber-crimes. Financial institutions and third-party providers must remain vigilant, continually assessing new risks and adapting their security protocols. Innovations such as blockchain, AI-based fraud detection systems, and quantum cryptography are expected to play key roles in securing open banking transactions.

    'Category': ['Transport', 'Shopping', 'Food', 'Travel', 'Groceries']
}
df = pd.DataFrame(data)

# Encoding categorical variables
le = LabelEncoder()
df['Merchant'] = le.fit_transform(df['Merchant'])
df['Category'] = le.fit_transform(df['Category'])

# Splitting data
X = df[['Amount', 'Merchant']]
y = df['Category']
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2,
 random_state=42)

# Training a simple AI model
model = RandomForestClassifier()
model.fit(X_train, y_train)

# Predicting a new transaction category
new_transaction = [[200, le.transform(['Amazon'])[0]]]
predicted_category = model.predict(new_transaction)
print("Predicted Category:", le.inverse_transform(predicted_category))

This script showcases how AI can categorize transactions based on historical data, an essential feature in AI-driven financial management tools.

Conclusion

AI is transforming open banking for SMEs by offering smarter financial management tools, improving lending processes, and reducing risk.
