Recently, the fingerprint lock electronic lock market is very popular. Fingerprint lock manufacturing principles how? Today we talk about. Say fingerprints will eventually be traced back to ancient China. According to related statistics, the first fingerprint application of our ancient can be traced back to the Qin Dynasty. To the Tang Dynasty, the fingerprint of the representative of the press refers to as the book according to India in the instruments, contracts and other civil applications widely used. Since the Song dynasty onwards, the fingerprint is used to do criminal proceedings physical evidence. In Europe, in 1788, Meyer (J.Mayer) first proposed that no two people's fingerprints identical; 1889, Henry (ERHenry,) on the basis of summing up the results of previous studies, the proposed fingerprint minutiae recognition theory, laid the foundation of modern fingerprint science. The fingerprint recognition technology from when he was found to be widely used in contracts and other civilian areas. The human fingerprint has a life-long stability and uniqueness, and soon be used in criminal investigations, and the title of "evidence first. The early fingerprint identification methods used artificial than the right, low efficiency, slow, can not meet the needs of modern society. The late 1960s in the United States, it was suggested that fingerprint analysis using computer image processing and pattern recognition methods to replace the artificial comparison, this is the Automated Fingerprint Identification System (AFIS). Costs and the special requirements of the operating environment, when used in the main limited to the criminal investigation is also called the police field. With the computer image processing and pattern recognition theory and LSI technology continues to evolve and mature, the Automated Fingerprint Identification System volume is shrinking, their prices have been reduced, they have been applied to civilian areas. Biometric identification as emerging authentication technologies, has irreplaceable advantages. The potential risks and opportunities from policy-oriented, from the current situation, especially the "9.11", it will be the international community ", the new century, Ten high-tech one of the most promising; for domestic, biometric-based authentication will also be encouraged by the state and development of one of the key technologies. According to the forecast of the International Biometric Authentication Group (IBG): biometric authentication market in 2002 exceeded $ 700 million, which accounted for nearly 50% of fingerprint identification, iris recognition is accounted for 8%. U.S. biometric authentication market in 2005 will reach $ 1.9 billion will account for 40 percent, fingerprint recognition, iris recognition will account for about 10%; U.S. biometric authentication market in the coming years will still maintain its high growth trend, the fingerprint was maintained at 30 %, the iris will remain at around 50%. Market research firm, according to a global authority on this forecast of the China market: China Fingerprint Identification market in 2002 exceeded 1 billion yuan, about 50 percent growth rate in 2005 will exceed 3.5 billion yuan. Iris recognition market revenue is expected to exceed 500 million yuan in 2005, will maintain a growth rate of 80% in the next five years. The country is becoming after the United States, Japan, the most promising developing markets, is expected in the next five years, the biometric authentication market revenue will reach 30 billion yuan.
