Is the fingerprint lock reliable? What is the principle?

2022/05/23

Whether the fingerprint lock is reliable or not depends on the identification ability of the fingerprint lock, and the identification ability of the fingerprint lock mainly depends on the algorithm accuracy of its built-in identification software, so what is the principle of the fingerprint lock? The principle of fingerprint lock: After the touch screen of the fingerprint lock extracts the visitor's fingerprint, the fingerprint information is fed back to the server side of the fingerprint lock. The server mobilizes various algorithms to analyze the fingerprint, and compares it with the user's fingerprint stored in the system. The comparison results are quantified. If the similarity is higher than a certain value, it will be considered that the two fingerprints are the same, and an instruction to agree to open the door will be returned, otherwise, the door will be refused.​​ Fingerprint locks are smart locks. It is the perfect crystallization of computer information technology, electronic technology, mechanical technology and modern hardware technology. The characteristics of fingerprints have become important evidence for identification, so they are widely used in public security, criminal investigation and judicial fields. It can be said that fingerprint authentication is quite convenient, fast and precise. .
