The past and present of fingerprint recognition technology

Fingerprint recognition technology is now widely used in the security market, and we always think it is the product of high technology. However, any technological invention originates from small things around. Xiao Bian today read about the past and present of fingerprint recognition technology for people who are curious about science and technology.

The earliest history of fingerprint recognition technology dates back to the Qin Dynasty in China. At that time, the "fingerprint" represented fingerprint printing has been widely adopted in civil affairs such as documents and contracts. In the Song Dynasty, "signing and drawing" had become one of the physical evidence of criminal proceedings.

By 1788, European Mayer proposed: "No fingerprints would be exactly the same for two people." In 1889, Henry used a large number of experiments to prove that the skin texture on the fingers is impossible at the patterns, breakpoints and intersections. The same, laid the foundation for modern fingerprinting directly.

Although China has relatively early knowledge of some of the basic science and technology-related knowledge, it is less devoted to higher-level applications than the West. This is reflected in many aspects, in addition to fingerprint technology, as well as the gunpowder compass.

After centuries of manual comparisons, by the middle of the 20th century, Americans had put fingerprint recognition technology on computers and developed the Automatic Fingerprint Identification System (AFIS). Opened a new era of fingerprint technology.

The automatic fingerprint recognition system collects, analyzes, and compares live fingerprints through special photoelectric conversion devices and computer image processing technologies, and can identify individual identities automatically, quickly, and accurately. Because of its low cost and simple operation, it quickly gained popularity in the police and civil markets. In 2012, the global fingerprint authentication market has exceeded the $5 billion mark.

China's fingerprint recognition research began in the 1980s and mastered the core technologies. The development is basically synchronized with foreign countries. In the application of fingerprint biometric technology, attendance systems and equipment are the first to enter the scale of production and sales. Fingerprint attendance system has good cost performance, convenience, and ease of use, which is the main reason for its successful promotion. Although all the way to the impact of other biometrics technology, but fingerprint recognition technology still maintains a great lead, in particular the emergence of fingerprint recognition computer and fingerprint recognition mobile phones, so that fingerprint recognition technology has taken a new level.

Although China started late in the exploration of the application of fingerprint technology in science, we are pleased to see that we have realized the importance of technology applications. Therefore, the future of Chinese science and technology is still promising.

At present, the cost of fingerprint recognition products is declining, and the product form is becoming more and more abundant. At present, the sales volume of fingerprint attendance products in the Chinese market accounted for more than 40% of the total sales of biometric products, ranking first. In consideration of public safety and commercial leakage, more than 80% of the companies in the high-end electronics market have begun mass production of electronic products with additional fingerprint identification systems.

In this way, did you find out that technology is not so profound?
