Electronic lock manufacturers tell you the common sense of smart fingerprint locks

Fingerprint lock experts teach you some useful tips about fingerprint locks. What is fingerprint? Human skin is composed of three parts: dermis, epidermis and subcutaneous tissue. The lines on the palms of our hands and the inner surfaces of our fingers, feet, and toes will form a variety of patterns. The pattern of a human finger is a fingerprint. Due to genetic characteristics, although fingerprints are different for each person, they are different. So these fingerprints are unique. Fingerprint lock is a new type of lock. It is a lock with human fingerprint as the identification carrier. It is the perfect crystallization of fingerprint identification technology, electronic technology, mechanical technology and modern hardware technology. Generally speaking, locks that can be opened with fingerprints, passwords, various function cards, and spare mechanical keys can all be called fingerprint locks. What is biometric fingerprint identification technology? It adopts real living fingerprint identification technology, which can identify skin dermal fingerprints, and can identify the subtle temperature and humidity of the skin, ensuring that it is an advanced technology that can only be identified by a living body, and avoiding copying fingerprints to confuse and pass the security Sexual technical issues. According to the uniqueness and stability characteristics of biological fingerprints, we can save the biological fingerprints of the biological fingerprints in advance. By comparing his (her) biological fingerprints with the pre-saved biological fingerprints, we can accurately verify his real identity. What is an automatic fingerprint identification system? The automatic fingerprint identification system collects, analyzes and compares living fingerprints through special photoelectric conversion equipment and computer image processing technology, which can automatically, quickly and accurately identify personal identity. Generally, it can be divided into two parts: 'offline part' and 'online part'. The offline part includes the main steps of collecting fingerprints with a fingerprint collector, extracting minutiae points, and saving minutiae points in a database to form a fingerprint template library. The online part includes collecting fingerprints with a fingerprint collector, extracting minutiae points, and then matching these minutiae points with the template minutia points stored in the database, and judging whether the input minutiae points and the template minutiae points are from the same fingerprint. After adopting advanced photoelectric identification methods to collect a biological fingerprint information, it can be turned into a code that can be compared with the password that has been processed by the computer. These codes are encrypted, and then identified and judged by unique related algorithms. Some of the algorithms use all patterns of a biological fingerprint, and some of them are special details of biological fingerprints.
