Challenges and Considerations in Implementing AI

The integration of AI in the finance and banking sector presents several challenges and considerations that must be addressed to ensure responsible and ethical implementation. These include data security concerns, regulatory compliance, and mitigating potential biases and discrimination.

Data Security

The use of AI technologies in finance creates new opportunities for threat actors to exploit sensitive data. The data used to train AI and machine learning (ML) models is often highly sensitive and distributed across various systems, including third-party data stores. If hackers gain access to this data, they could impersonate customers in identity fraud attempts or launch sophisticated data poisoning attacks.

Data poisoning occurs when threat actors delete or manipulate specific data points in the training data to sabotage AI/ML models, introduce vulnerabilities, or achieve predetermined aims. This could result in disruptions to critical systems like fraud detection, customer authentication, or process automation. Threat actors may employ data poisoning to hold organizations for ransom, bypass security checks like Know Your Customer (KYC) authentication, or cause financial and reputational damage by sabotaging key business processes.

To mitigate these risks, a data-centric security approach is crucial. This involves automatically discovering, classifying, and protecting data across the enterprise, regardless of its location. Technologies like tokenization enable organizations to continue using data for AI model training while maintaining security. However, data-centric security alone is not sufficient; it must be combined with strict access controls, asset management, continuous monitoring, supply chain risk management, and staff training.

Regulatory Compliance

As AI adoption in finance continues to grow, regulatory bodies are actively developing frameworks to govern its use. While existing regulations provide some guidance, the landscape is rapidly evolving, requiring financial institutions to remain vigilant.

In October 2023, the U.S. President issued an Executive Order on AI, establishing new standards for safety and security, including safety testing, authentication standards for AI-generated content, and cybersecurity programs to address software vulnerabilities.  Additionally, proposed legislation like the Algorithmic Accountability Act of 2023 aims to protect consumers from potential harm caused by AI systems used in decision-making processes related to housing, credit, and education.

Privacy and data protection laws, such as the Gramm-Leach-Bliley Act (GLBA), the California Consumer Privacy Act (CCPA)/California Privacy Rights Act (CPRA), and the General Data Protection Regulation (GDPR), must also be considered, as AI usage often involves processing personal information. Financial institutions, with access to vast amounts of personally identifiable information, must ensure compliance with these regulations.

Another critical area is mitigating discrimination and bias in AI systems. Since AI models can learn and replicate biases present in their training data, leading to discriminatory outcomes, financial institutions must implement measures to avoid a “bias in – bias out” situation. This can be achieved, in part, by implementing robust compliance solutions.

As the regulatory landscape continues to evolve, financial services firms must prioritize data quality and security, thoroughly audit AI model outputs, and document processes for auditing purposes. Firms must also develop comprehensive AI risk, legal, and compliance frameworks that address global, federal, state, and industry-specific regulations, as a complex patchwork of laws and regulations is likely to emerge.
