- Artificial intelligence has the capability to extract fingerprints from high-resolution photographs of individuals posing with the V-sign, particularly showing the lower part of their fingers.
- This method relies heavily on the common selfie taking distances, typically between 1.5 and 2 meters, which provide ample quality for AI to reconstruct hand ridges.
- For fingerprint extraction to work, the hand must be oriented towards the camera with the lower part visible; otherwise, insufficient information is present.
- At specific distances like less than 1.5 meters, detail recovery is high, while between 1.5 and 3 meters the system obtains half the necessary information, and above three meters reliability declines.
- The process, which can yield fingerprints from two fingers if the image resolution is adequate, may compromise biometric security when combined with advanced editing tools and AI.
- The success of this biometric theft depends also on an attacker having access to the device intended for the unauthorized authentication, highlighting the dual vulnerabilities of proximity and device access.
