The digital age has unlocked remarkable opportunities but also exposed us to critical challenges, with identity fraud standing as one of the gravest threats. As cybercrime grows more sophisticated, the need for advanced identity verification has become more urgent than ever. In 2024, identity fraud reached unprecedented levels, with 5.7 million fraud reports in the U.S., of which 1.4 million involved identity theft, according to the Federal Trade Commission. Artificial intelligence (AI) is reshaping this landscape—introducing new risks and innovative solutions to protect identities and combat fraud.

The Core of Identity Verification: Knowledge, Possession, and Inherence
To establish and verify identity, organizations rely on three fundamental factors:
- Knowledge – Information only the user knows, such as passwords or PINs.
- Possession – Objects or devices the user has, like a smartphone or security token.
- Inherence – Unique biological traits, including biometrics like facial recognition, fingerprints, and voice patterns.
A comprehensive identity verification system integrates all three elements to create a robust defense. None can be sacrificed, as each adds a critical layer of security. Biometrics, based on inherence, are emerging as the cornerstone of modern identity protection.
The Dual Impact of AI on Identity: Risks and Solutions
AI has made it significantly easier for fraudsters to fabricate convincing fake identities. Using basic public data—like names, photos, or videos—cybercriminals can create deepfakes, realistic AI-generated imitations of real people. This accessibility has led to a staggering surge in fraud attempts, with a 2137% increase in deepfake fraud attempts between 2021 and 2023, making scams faster, cheaper, and more widespread.
The Opportunity: AI-powered Biometrics as a Defense
While AI poses new challenges, it also offers tools to counter these threats. AI-powered biometrics deliver secure, privacy-first authentication systems, offering several key benefits:
- Built-in Security: Biometrics rely on unique physical traits, making them highly resistant to manipulation or forgery.
- Privacy by Design: Properly implemented biometric systems eliminate the need for storing sensitive personal information.
- Low Theft Risk: Unlike passwords or tokens, biometrics cannot be stolen and reused. To date, there have been no significant breaches of biometric data, underscoring its reliability.
These innovations transform biometrics into a formidable shield against identity fraud.
Privacy and Security: A Harmonized Solution
Biometric technology has often faced skepticism due to concerns about privacy breaches. However, with advancements such as Renewable Biometric References (RBRs), it is now possible to achieve both robust security and data privacy simultaneously. Here’s how:
RBRs protect users by ensuring biometric data cannot be reverse-engineered or misused to create synthetic identities. Traditional biometric systems often store raw biometric data, which, if stolen, can be exploited for malicious purposes. RBRs, however, use encrypted, non-reversible representations of biometric data, ensuring that even if hackers access this data, it cannot be reconstructed into usable forms.
RBRs pose no inherent risk if compromised, as they are non-permanent, non-interoperable, and revocable. Unlike passwords or tokens, which are static and transferable, RBRs are designed to expire or be invalidated after a certain period or under specific circumstances. They cannot be used across systems (non-interoperable) and can be revoked, allowing users to reset their biometric credentials without long-term consequences if a breach occurs.
Modern systems strike a balance by granting users control over their biometric data and utilizing technologies like RBRs. They ensure both privacy and security are preserved without compromising functionality or user trust.

The Need for Regulation: Balancing Innovation and Risk
As the use of biometrics continues to expand, thoughtful regulation becomes increasingly important to protect users and maintain trust. However, directly regulating the technology itself—such as imposing rigid restrictions on biometric systems—could inadvertently stifle innovation and limit its potential.
A more balanced approach is the adoption of frameworks like the Artificial Intelligence Act, which emphasizes a risk-based approach. Instead of broadly restricting the technology, this method evaluates the specific context and application of biometrics. By tailoring regulations to the risk levels posed by different use cases, such frameworks ensure both safety and fairness while encouraging technological advancement.
For example, high-risk applications like law enforcement biometrics may require stricter oversight, whereas everyday consumer authentication systems could benefit from lighter regulation that prioritizes user transparency and data protection. This nuanced approach enables organizations to innovate responsibly while mitigating risks.
Looking Forward: AI’s Role in Identity Protection
The emergence of AI has ushered in a new era of both challenges and opportunities in the realm of identity. As deepfakes, synthetic identities, and injection attacks grow more sophisticated, organizations must adopt comprehensive, multi-layered approaches to security. By leveraging AI-based biometrics and adhering to thoughtful regulatory frameworks, it is possible to create systems that are not only secure but also private and user-centric.
The balance between security and privacy is no longer a compromise. With AI and biometrics working in tandem, organizations can provide seamless user experiences while maintaining robust defenses against fraud. The future of identity verification lies in innovation, collaboration, and a commitment to protecting individuals in an increasingly digital world.
