Philip Ingram MBE puts the integration of biometrics and artificial intelligence under the lens.

In today’s rapidly evolving digital landscape, the need for robust security measures has become paramount. Traditional security methods are no longer sufficient to protect sensitive information and assets. This has led to the emergence of innovative technologies such as biometrics and artificial intelligence (AI) to enhance security systems. Biometrics refers to the measurement and analysis of unique physical or behavioural characteristics, while AI involves the development of intelligent machines capable of mimicking human cognitive functions. When combined, biometrics and AI can revolutionise the way we approach security.

Biometrics plays a crucial role in enhancing security by providing a reliable and accurate way to identify individuals. Unlike traditional security measures such as passwords or ID cards, biometric features are unique to each individual and cannot be easily replicated or stolen. This makes it significantly more difficult for unauthorised individuals to gain access to secure areas or sensitive information. Biometric technologies can include fingerprint scanning, facial recognition, iris scans, voice recognition, and even DNA analysis.

These technologies have the potential to create a robust security framework that is both convenient and highly secure. Biometric technologies are also flexible and can be integrated into various security systems. For example, fingerprint scanners can be used to control access to physical locations, facial recognition can be utilised for identity verification in airports or banks, and voice recognition can be implemented for secure telephone banking. The versatility of biometrics makes it a powerful tool in enhancing security across different industries and sectors.

Biometrics and AI in application

The applications of biometrics and AI in security are vast and diverse. In the banking sector, biometric authentication methods such as fingerprint or facial recognition are being used to secure online banking transactions, making it virtually impossible for hackers to gain unauthorised access to customer accounts. In airports, facial recognition technology is being employed to streamline the boarding process and enhance border control. Law enforcement agencies are using biometrics to identify criminals and suspects, helping to solve crimes more efficiently. These real-world applications demonstrate the effectiveness and potential of biometrics and AI in enhancing security across various industries.

While biometrics and AI offer numerous benefits in enhancing security, there are also challenges and concerns that need to be addressed. Privacy is one of the primary concerns when it comes to biometrics, as the collection and storage of individuals’ personal data raise ethical questions. There is a need for clear regulations and guidelines to ensure the responsible use of biometric data and protect individuals’ privacy rights.

Another challenge is the potential for biometric data to be compromised. As with any technology, there is always a risk of hacking or data breaches. It is crucial for organisations to implement robust security measures to safeguard biometric data and ensure its integrity. Additionally, biases and inaccuracies in AI algorithms can pose challenges, especially in facial recognition technology. These concerns need to be addressed to ensure that the benefits of biometrics and AI in security are maximised while minimising the risks.

However, with the advent of generative AI, a subset of artificial intelligence (AI), it presents significant challenges to the field of biometrics and security. One of the main concerns with generative AI is its ability to generate realistic synthetic images and videos that can easily trick biometric systems. By leveraging deep learning algorithms, generative AI can create highly convincing facial images or even entire personas that do not exist. This poses a serious risk to biometric systems that rely on facial recognition or other physical attributes for authentication.

The World Economic Forum describes generative AI as “a category of artificial intelligence algorithms that generate new outputs based on the data they have been trained on. Unlike traditional AI systems that are designed to recognise patterns and make predictions, generative AI creates new content in the form of images, text, audio, and more.”

The threat from generative AI lies in its potential to undermine the reliability and accuracy of biometric systems. If an attacker can generate synthetic images or videos that closely resemble the biometric data of an authorised individual, they can potentially bypass security measures and gain unauthorised access. This could have serious implications in various industries, including finance, healthcare, and national security. To mitigate the threat from generative AI to biometrics, researchers and industry experts are developing robust countermeasures.

Heather Federman, the Vice President of Privacy & Policy at BigID in her account of a recent Instagram hack, highlights the potential dangers posed by generative AI. “Hackers can use this technology to create synthetic identities that closely resemble real individuals, making it easier for them to bypass biometric security measures. This raises serious privacy and security concerns, as sensitive personal information can be easily exploited.”

One approach is to enhance biometric systems by incorporating additional layers of security, such as multi-factor authentication. By combining biometric data with other authentication factors, such as passwords or tokens, the risk posed by generative AI can be significantly reduced. Another approach is to develop advanced algorithms that can detect and differentiate between real and synthetic biometric data. By analysing patterns and anomalies in the data, these algorithms can effectively identify fraudulent attempts to deceive the system. Ongoing research in this area is crucial to stay ahead of emerging threats and ensure the continued security of biometric systems.

Other ways of mitigating the generative AI threat include the integration of multiple biometric features. For instance, a system can combine fingerprint and facial recognition to create a multi-factor authentication process, further enhancing security. These advancements in biometric technologies are continually pushing the boundaries of what is possible in terms of security, paving the way for a future where biometrics will be the norm.

The future of security lies in the seamless integration of biometrics and artificial intelligence with measures to ensure the threats from generative AI and whatever comes next are properly mitigated. As technology continues to advance, we can expect more sophisticated and accurate biometric identification methods. Contactless biometrics will become more prevalent, offering enhanced convenience and hygiene.
