Analysis of Fingerprint Lock Fingerprint Recognition Technology's Rejection Rate and Anticipation Rate

Since ancient times, people have stressed that "living in peace and well-being" is a good time to live in. Having a comfortable, safe home is the foundation of a happy life. The home is a sheltered harbor. It is a stage that releases nature and a castle that protects the safety of people and property. The lock is the frontier and most solid barrier that separates the happy home from the outside world. It is also the self-world and the external world. The extension of the wilderness. From rope locks, wood locks, to triple reed locks, rotary locks, and mechanical locks, from simple to complex and sturdy evolution, people are increasingly eager for safety and happiness. That said below is the fingerprint lock, its refusal rate and refusal rate.

The Analysis of Fake Rejection Rate and Anticipation Rate of Fingerprint Identification Technology

With the popularity of smart fingerprint locks, we often encounter various problems when purchasing smart fingerprint locks. For example, some professional terms about fingerprint locks cannot be understood, for example, what is the refusal rate of fingerprint lock fingerprint recognition? False rate? In simple terms, the refusal rate of the smart lock fingerprint recognition is the same fingerprint, which is identified by the algorithm as not the same; the Falsehood rate of the smart lock fingerprint recognition is not the same fingerprint, and is recognized by the algorithm as the same.

Fingerprint lock fingerprint recognition refusal rate and Falsehood rate, also known as rejection rate and false positive rate. The refusal rate (FRR) means that the real fingerprint image is regarded as false. The false recognition rate is FAR, which means the fake fingerprint image is considered as true. The fingerprint rejection fingerprint rejection rate and false-finding rate are related to the resolution of the fingerprint acquisition window and the fingerprint identification technology.

The refusal rate and falsification rate of the fingerprint identification of the fingerprint lock is an important index to evaluate the quality of the fingerprint lock fingerprint. The refusal rate and the falsification rate of the fingerprint lock fingerprint identification directly affect the response time and identification of the fingerprint lock. Fingerprint accuracy, thus affecting the user's experience and the security of the fingerprint lock. The resolution of the fingerprint heads on the market is now over 500 DPI, which means there are 500 pixels per inch, that is, there are 500 information points in the fingerprint image per inch.

Prior to the release of the Ministry of Public Security, the standards for refusal rate and falsehood rate were: refusal rate should be less than 3%, and false rate should be less than 0.001%. According to the relevant standards, the security level of smart locks for household entrance doors should be 3, that is, rejection rate is less than 0.1%, and false acceptance rate is less than 0.001%. The fingerprint resolution used by many smart lock brands is also within this range, and specific indicators may be different. However, as long as it is a branded product, the user experience will not be substantially different.

There is a trade-off relationship between “rejection rate and falsehood rate”. At the same level, the refusal rate is high and the falsification rate is low, and vice versa. This is an inverse relationship. However, if the level of technology and technology is improved, both of these indicators can be lowered. In essence, it is still necessary to raise the level of technology.
