Is fingerprint lock safe?
Fingerprint lock can be understood as a mechanical lock with fingerprint unlocking function, rather than a fingerprint lock with a spare mechanical lock. Whether fingerprint or password technology is blown to the skies, as long as the back door is leaky, its security performance is not much different from that of ordinary mechanical locks.
If fingerprint anti-theft locks can only rely on fingerprints, then security is really great. Fingerprint recognition has developed to be a living fingerprint. It is impossible to imitate a fingerprint without intentionally copying it.
The fingerprint film that can open the fingerprint lock needs to press the finger on the mold for at least 3 minutes to reproduce, and it is impossible to take the fingerprint from the wine cup and reproduce it in the film. Don't look at the bridge in the movie and think it's easy to open the door by stealing fingerprints.
Fingerprint recognition algorithm is a comprehensive model which combines the algorithms of each link in a process framework. Generally speaking, it can be divided into three parts: image enhancement, geometric registration and scoring decision. The solution of fingerprint door lock sticking film is aimed at the loopholes in the judgment link.
"If we retrieve the results, there may be several situations, such as the use of image algorithms, or the low level of traditional fingerprint feature point algorithms," the experts said. "Fingerprint feature extraction is not good, for example, there are many false details. When we finally decide whether to unlock, we may only recognize them."
Because most intelligent locks still have mechanical locks, the only compulsory implementation standard of intelligent locks is "GA/T 73-2015", which clearly points out that China's mechanical locks are divided into three ABC levels. The difference between the levels is the length of opening time.
