Artificial intelligence (AI) is increasingly seen as an ally of cybersecurity for its optimizations and improvements thanks to self-learning, prediction and analysis of patterns and behaviors.
With these abilities, it increases accuracy and response against different scenarios. But it also has a flip side: it allows cybercriminals to carry out more sophisticated attacks that are more difficult to detect. Let’s analyze, for example, the case of AI and biometric data.
We call biometrics the use of unique biological characteristics (the iris of the eye, fingerprints, our face) for digital authentication. Until now, this technology served as a secure validation to protect the most personal and sensitive information. But… How long will it remain an effective mechanism?

Non-legal uses of AI with biometric data
The use of AI in aspects involving biometric and audiovisual data has developed a lot in recent times. This tool allows the use of deep learning systems, which helps to develop, for example, a near-perfect imitation of a person’s voice.
This could be used to enter an online meeting to which one is not authorized. Also, to fool a recognition system. At this point, it is possible to cite numerous podcast talks, chatbots, virtual presenters and innovations that have imitated the human voice through generative AI.
This is just one example. Fingerprints, facial and iris recognition are other aspects that risk being hacked. This, of course, if they are not used with the necessary responsibility. To sum up, AI could be used to analyze, process and use biometric data for an unlawful purpose.
With fingerprints, it will be possible to create forgeries or circumvent management system controls. With facial recognition, it will be possible to create techniques to generate false images or steal images or patterns from the system that hosts them in order to deceive authentication systems.
Iris recognition continues to be one of the most secure biometric methods and one of the most widely used in airports and banks. Its benefits: its low false positive rate and its effectiveness, as it has more unique patterns that differentiate it from other recognition methods.
AI and biometric data: Countermeasures for greater security
Of course, it is also possible to apply control and countermeasure to these potential vulnerabilities with solutions that incorporate AI engines.
It is essential to consider the interfaces that our systems will support (in this case, voice). In this way, the necessary controls are incorporated to validate the authenticity of the input or minimize the risks associated with the probability that it may occur.
In any case, it is important to note that, although generative AI can produce data that to the human eye appear truthful, there are techniques that validate that an image or content has not been generated by an AI model.
Preventing is important
Keeping up to date with new control technologies is essential. The same goes for the ability to be one step ahead in identifying how to mitigate these threats that may affect our information.
It is true that there are no infallible mechanisms or tools. But complementing current technologies with the incorporation and knowledge of how AI engines work will be of great help in their prevention.
On the other hand, it is also key to update policies and procedures. This is what allows us to keep our documentation up to date when defining the scope of our assets and their controls.
Conclusions
It is crucial to strengthen solution development processes, integrating cybersecurity from early stages.
Organizations have to be aware and constantly updated to cope with changes, which are occurring at great speed. And while each AI engine or platform has its own security guidelines, close attention must be paid to how sensitive information is manipulated.
At Nubiral we have an area specialized in cybersecurity that can help you with all these challenges.
The key lies in maintaining a balance, where protection technologies advance at the same pace as emerging threats. Only in this way, and through a comprehensive approach, can AI be secured as an ally in the protection of our most valuable data.
