Face recognition technology is the most widely used the most convenient to use
The research of face recognition system began in the 1960s and 1980s and the development of computer technology and optical imaging technology was improved and the real stage of application was in the late 90s and in the United States Germany and Japan. Technology to achieve the main. Today the application of face recognition technology has not only limited to business places it has a variety of intelligent home in the form of gradually penetrate into the ordinary people home. However the face recognition system information storage is still the computer can identify the language that is digital or specific code security will be discounted. Perhaps many female friends on the face recognition function miserable change a hairstyle draw a makeup it can not be identified.
Fingerprint recognition technology is mature but not applicable to everyone
Each fingerprint has several unique measurable feature points each feature point has about seven characteristics people's ten fingers produce at least 4900 independent measurable features. Fingerprint recognition technology by analyzing the fingerprint can measure the feature points from which eigenvalues and then certification. At present China's second generation ID card will achieve a fingerprint collection and the major smart phones have to achieve the fingerprint unlock function. Compared with other biometric technologies fingerprint recognition has long been widely used in consumer electronics security and other industries through the time and practice of testing technology is also constantly innovate. Although each person's fingerprint recognition is unique but does not apply to every industry everyone. For example people who have long-term manual hands will be troubled by fingerprint identification their fingers if the slightest damage or dry and wet environment stained with foreign body fingerprint function to be invalid.
Iris recognition of biological certification technology "darling" safety in the first place
Compared with other biometrics iris recognition and error rate have reached the recognition level of zero probability and iris recognition is non-contact recognition convenient and efficient identification. Iris is unique to each person with the uniqueness of reproduction the security level is currently the highest. But the iris recognition of the application price is also proportional to its technical difficulty compared to other identification technology slightly expensive.
Voiceprint to identify low cost easy access strict application requirements
The so-called voiceprint is the use of electro-acoustic instruments to display the voice of the acoustic spectrum. It is very suitable for remote identification only need a microphone or phone mobile phone can be through the network (communication network or Internet) to achieve remote login. However the shortcomings of voiceprint recognition is also very obvious the requirements of the environment is very high in a noisy environment mixed voice under the voice is not easy to obtain; human voice will be with age physical condition age mood and other effects Change; different microphones and channels have an impact on recognition performance.
Vein recognition speed the product is difficult to miniaturization makes the market use low
Recently the media reported Shennongjia scenic spot refers to the intravenous ticket machine the ticket only 3 seconds effectively alleviate the peak area of the peak area of the phenomenon of congestion. Vein recognition is through the finger vein identification device to obtain personal finger vein distribution map the eigenvalues stored. Comparison real-time to take a vein map extract the eigenvalues to match so the identity of the individual identification. Today's vein recognition has four major characteristics: a high degree of security easy to use fast identification and highly accurate. The most important point is that the characteristics of finger vein recognition have been internationally recognized as unique and comparable to the retina in the case of their rejection rate (the same structure and the algorithm is identified as different) less than one ten thousand Its knowledge rate (different structure and the algorithm is identified as the same) can be less than one hundred thousandth. However the current use of vein recognition in the market is not high and it also has a difficult to avoid the shortcomings. For example the dorsal vein may still change with age and physiological changes the permanent has not yet been confirmed; there is still the possibility of successful registration; due to the collection by their own characteristics of the restrictions the product is difficult to miniaturization; collection equipment has special requirements The design is relatively complex high manufacturing costs.
In general with the development of the times the continuous progress of technology biometric technology will usher in new changes and needs biometric technology and the Internet the intersection of things will become the focus of the industry. The current single biometric technology has its own advantages and disadvantages in the application will inevitably have a problem. Perhaps the future of biometric technology will be developed to diversify learn from each other and biometric technology market prospects is still worthy of attention.
