Winston Churchill. The famous V
They estimate that images in which fingers are close to the camera (within about 1-1.5 meters) may contain enough skin surface detail to partially restore papillary lines, Techkult writes. We are primarily talking about high-resolution images, including selfies and burst photography.
Experts note that the development of computer vision methods and AI increases the potential realism of such attacks. In theory, such data could be used to attempt to bypass biometric authentication systems, including devices and payment services.
The discussion of the topic intensified after statements by cyber expert Li Chan, who claimed that modern algorithms are capable of extracting elements of the structure of papillary lines even from ordinary images. The topic spread in Chinese social networks, where the “V” gesture is often used in selfies.
That said, such research is not new. Back in 2013, security researcher Jan Krissler demonstrated the possibility of reproducing fingerprints from photographs. In subsequent years, other experiments have also shown that biometric data can be partially recovered using images and specialized equipment.
Experts emphasize that despite the potential risks, biometric authentication remains widespread due to its ease of use and high speed of access.
