What is the refusal rate and falsification rate of smart lock fingerprinting?

With the popularity of smart locks, we often encounter various problems in the purchase of smart locks, like some professional terms on fingerprint lock we can not understand, such as what is the refusal rate and falsification rate of smart lock fingerprint recognition. ? What follows is a description of what is the refusal rate and falsification rate of fingerprint locks.

In simple terms, the refusal rate of the smart lock fingerprint recognition is the same fingerprint, which is recognized by the algorithm as not the same; the Falsehood Ratio of the smart lock fingerprint recognition is not the same fingerprint and is identified by the algorithm as the same.

The refusal rate and falsification rate of smart lock fingerprint recognition can also be called rejection rate and false recognition 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 smart lock fingerprint recognition is an important index to evaluate the merits of the fingerprint lock fingerprint. The refusal rate and falsification rate of smart lock fingerprint recognition directly affect the response time of the fingerprint lock, and identify fingerprints. The 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 households entering households should be 3, that is, the rejection rate is less than 0.1%, and the false acceptance rate is less than 0.001%. The fingerprint resolution used by many smart lock brands is also within this range, and the specific indicators may differ, but as long as it is a brand manufacturer's products, 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. However, in order to speed up certification, some manufacturers use the method of lowering the security level to sacrifice the safety at the expense of creating illusions of high speed and high recognition ability. This situation occurs in some model locks or demo locks. We don't want to buy and use for some model locks.

The refusal rate and falsification rate for what is a smart lock are shared here today, hoping to help everyone.

I. Characteristics of polyurethane adhesive

Strong bonding force: It has excellent bonding performance to various materials, including metals, plastics, rubbers, woods, etc.

Good flexibility of polyurethane adhesive: After curing, it has certain flexibility and can adapt to the deformation and vibration of materials.

Good water resistance: It can maintain good bonding performance in a humid environment.

Chemical resistance: It has a certain resistance to chemical substances such as acids, alkalis, and salts.

Adjustability: Different performance requirements can be met by adjusting the formula and curing conditions.

II. Uses of polyurethane adhesive

Wood processing: Used for splicing and gluing of wood, which can improve the strength and stability of wood products.

Automobile manufacturing: Used for bonding of automobile interior parts and sealing of car body structures.

For construction field by polyurethane adhesive: Used for bonding of insulation materials and construction of waterproof materials.

Footwear manufacturing: Used for bonding the sole and upper of shoes and has good durability.

Packaging industry: Used for sealing and pasting of cartons and paper boxes and can bear a certain weight and pressure.
