On September 16, Pei Zhiyong, a network security expert and director of Chianxin Industrial Security Research Center, wrote in Weibo that it is not technically difficult to copy fingerprints through photos, but it will not substantially expand security risks.
Fingerprints are everywhere where people touch them. If someone is targeted by thieves or people around him, his fingerprints are easy to get. To prevent the risk of fingerprint leakage, it is mainly to prevent thieves from entering the house or people around them from waiting for opportunities to steal. "Fingerprints are easy to leak, and shooting scissors does not substantially increase the risk of fingerprint leakage."
Not only fingerprints, but also biometric information such as faces and pupillary membranes can be easily copied or imitated. Therefore, in practice, the vast majority of security workers will only regard biometric technology as reading a series of passwords that are convenient to remember, rather than as a security verification technology. For complex systems with high security requirements, it is necessary to use dynamic encryption verification technology under zero trust mechanism.
"If the disclosure of fingerprints by scissorhands is discussed as a security issue, then it is best to tell everyone: don't take photos, or just take photos that don't show your face." At present, people can still use technologies such as paying by brushing their faces and brushing their faces. Responsible companies will not use biometrics as the only means of verification, but supplemented by artificial supervision, big data risk control, equipment locking and other auxiliary verification functions, thus providing users with a convenient and safe experience.
