Fingerprints are also common things in people's lives. In ancient times, people signed and printed a fingerprint, which represented a personal confirmation, such as painting. In modern times, fingerprint attendance machine, sign-in machine, fingerprint access control, fingerprint lock, mobile phone fingerprint unlock, fingerprint secret-free payment, or case detection are becoming more and more important in the field of biometrics.

Fingerprint identification is a unique and non-repetitive sign of a person. It can be used to judge the authenticity of a person's identity. Everyone's fingerprints are unique. And they are complex enough to provide sufficient features for identification. Fingerprint is not only unique, but also hereditary and invariant. It has not been found that different people have the same fingerprints, so each person's fingerprint is unique. As fingerprints are unique to everyone, in recent hundreds of years, fingerprints left by criminals at the crime scene have become an important clue for the police to track down suspects. Nowadays, fingerprint identification methods have been computerized, making the identification procedure faster and more accurate. It began thousands of years ago on earth.

According to the records, the ancients solved the case with the help of fingerprints during the warring States period more than 2500 years ago. although there was no high-tech fingerprint identification at that time, people realized the uniqueness of fingerprints in the pre-Qin period. as long as the naked eye can complete the effective identification of different fingerprints.

Especially when the fingerprint identification reached a very mature stage in the Song Dynasty, the dual nature and convenience of fingerprints, for the practical management of the common people, the Song Dynasty began to collect people's fingerprints on a large scale to set up an identification database. Just like today's second-generation ID card needs to record fingerprints before it can be activated. The recent discovery of "Yangshao fingerprint" has advanced the history of our country's cognition and application of fingerprints to the period of Yangshao culture more than 5000 years ago, which means that fingerprint identification has been popular for more than 5, 000 years.

However, although fingerprint recognition has a long history, mature technology, low cost, easy to use and many other advantages, but in today's biometric market, fingerprint recognition is no longer the "exclusive favorite". Because of the rise of artificial intelligence and the rapid growth of demand in finance, security, criminal investigation and other fields:

1: a single identification can not meet the requirements of market development.

2: fingerprint evidence is not as reliable as people have always thought, and the hypothesis that "everyone's fingerprints are unique" cannot be verified by scientific means.

3: fingerprint recognition has also exposed more and more defects and deficiencies in the long-term application, such as fingerprint may be worn and shallower, fingerprint is easy to be stolen and imitated and so on.

4: there will be very similar fingerprints in a family, and the shape of fingerprints is not immutable. People's age and changes in skin conditions will also affect the shape of fingerprints.

5: in addition, there are many external factors that affect people's judgment. As the fingerprints found by the police at the crime scene are often dirty or incomplete, people will inevitably make mistakes in identifying fingerprints. therefore, there are defects in the way of using fingerprints to identify criminals, which is easy to cause injustice.

Because, on the one hand, with the continuous promotion of artificial intelligence and the rapid growth of demand in finance, security, criminal investigation and other fields, a single identification method has been unable to meet the requirements of market development; on the other hand, fingerprint identification has also exposed more and more defects and deficiencies in long-term application, such as fingerprint may wear shallow, fingerprint is easy to be stolen and imitated and so on.

Based on this, in recent years, new recognition methods such as face recognition and iris recognition began to rise rapidly, especially the development momentum of face recognition technology is the most fierce, which has a strong trend to replace fingerprint recognition.

With the advent of 5G, and then to the future popularity, face recognition only takes a few seconds to scan, eliminating the link of contact with the device, so it is more convenient to apply and has a higher degree of practical universality. So fingerprint recognition can still survive? Will it be replaced?

Generally speaking, it is unrealistic to be completely replaced, because each has its own long time, just like pressing the handprint can not press the face, of course, it is convenient to press the fingerprint. Fingerprints can be used in relatively small spaces.

There are also more than 500 companies looking for fingerprint locks, such as Fuzhou Rihong fingerprint Lock Co., Ltd., registered capital: 1 million RMB, establishment date: July 07, 2010, there are 4 companies looking for face recognition.
