With the development of modern social economy and technology, the field of people's activities is expanding. Identity recognition technology is becoming more and more important in today's social life and economic activities, and fingerprint recognition has attracted people's attention because of its advantages of "security, ease of use and low price".

Fingerprint identification technology is internationally recognized as the most widely used, cheapest and most easy-to-use biometric authentication technology. Compared with other identity authentication technologies, automatic fingerprint identification has many unique information security advantages, which are embodied in the following aspects:

1. Everyone's fingerprint is quite fixed and will not change with the growth of people's age or the change of physical health, but people's voice and face may change greatly.

2. Fingerprint samples are easy to obtain, easy to develop identification system and strong practicability. At present, there is a standard fingerprint sample database, which facilitates the software development of the identification system; In addition, the hardware part of the fingerprint sampling function in the identification system is also easy to implement.

3. A person's ten finger fingerprints are different, which can easily use multiple fingerprints to form multiple passwords and improve the security of the system.

4. The template used in fingerprint identification is not the original fingerprint, but the key features extracted from the fingerprint. In this way, the system not only has a small storage capacity of the template library, but also protects the user's personal privacy.

5. After extracting the key features of the input fingerprint, it can greatly reduce the burden of network transmission, facilitate remote confirmation and support the network function of the computer.

We are also exposed to many fingerprint products in our life: fingerprint lock, fingerprint safe, fingerprint keyboard and fingerprint mouse. Fingerprint channel identification system...... it is conceivable that the application of fingerprint technology products improves the security and confidentiality efficiency required for work and life, adapts to the fast-paced lifestyle in the 21st century, and makes life simpler, more fashionable and easier! At the same time, it is more in line with the truth that science and technology is the first productive force. Today, the application of fingerprint technology will become a new growth point of China's economy, and its economic and social benefits will be immeasurable.
