Photo time, don't hold 2 inches. 🚨
Anyone who likes to take pictures and pretend to "Chu 2 inches" or Peace Sign may need to be more careful, because cybersecurity experts now warn that today's AI and high-resolution smartphone cameras can take ordinary photos to "fetch fingerprints" and may be used to forge identities in the future.
.
This trend began to be talked about heavily in China after Li Chang, a financial security expert, demonstrated through a television program that by taking a selfie with his fingertips clear enough, AI could enhance the contrast of fingerprints, even if the original image was blurred.
.
According to the report, if the image is taken at a distance of about 1.5 meters and the fingertips are facing the camera, there is a high chance that the system can extract fingerprint details, and images taken at a distance of 1.5 to 3 meters may also see some fingerprint information.
.
Although many parties consider it not an easy threat to the average user, experts agree that the AI technology of image adaptation is developing very quickly, reducing the cost and difficulty of extracting biomimetric data from photos.
.
A concern is that "fingerprints" are an irreplaceable biomimetic data, unlike a replaceable password. If the data is leaked, it may be used to unlock some kind of device, smartlock, or authentication system.
.
However, security researchers indicate that this attack also relies on high-quality images, clear angles, appropriate lighting, and may require multiple illustrations, so it is often a targeted attack rather than random hacking of ordinary users.
.
This is not the first time this has been warned, because back in 2017, Japanese researchers revealed that fingerprints could be read from photos taken about nine feet away.
.
Initially, experts suggest that if you have to post images to social media, you should avoid images that see fingertips too clearly, especially high-resolution images, or blur your fingerprints before posting to reduce the risk of biomimetric misuse.
