New Industry Focus: Biometrics
With the continuous improvement of biometrics, biometrics has gradually become known and understood by everyone. At present, biometrics is widely used for fingerprint, face and voice recognition. Now gradually in information security, personal consumer market, finance and other fields have been applied. Data show that in 2014 the scale of biometric breakthrough in billions of dollars mark, the biometric market in 2015 rose to 13 billion US dollars, is expected by 2020 the global biometric market will exceed 25 billion US dollars. The fingerprint identification market will have a market size of 13 billion U.S. dollars, speech recognition will be 5.6 billion U.S. dollars, face recognition will be 2.4 billion U.S. dollars, iris recognition will have 1.6 billion U.S. dollars, and other creatures will be 2.4 billion U.S. dollars.
Face recognition technology: the most widely used, the most convenient to use.
Face recognition system began in the 1960s. Today, the application of face recognition technology has not only limited to business establishments, it has been a variety of smart home gradually penetrate into the form of ordinary people home. However, face recognition system information storage is still based on computer-readable language, that is, numbers or specific code, security will be discounted. For example, women change hair, draw a makeup, face recognition can not be identified.
Fingerprint recognition technology: mature, but not for everyone.
Fingerprint recognition technology by analyzing the fingerprint measurable feature points, eigenvalues ​​extracted from, and then certified. Each fingerprint has several unique measurable feature points, each feature point has about seven features, people's ten fingers produce a minimum of 4900 independent measurable features. At present, China's second generation ID card will achieve the fingerprint collection, and all major smart phones have implemented the fingerprint unlock function. Compared with other biometric technology, fingerprint identification has been widely used in the fields of consumer electronics, security and other industries. Through the test of time and practice, the technical aspects are constantly being innovated. Although each person's fingerprint identification is unique, but not for every industry, everyone. For example, people whose hands are long-term hand-worked may have to worry about fingerprinting. Fingerprints may fail if their fingers are damaged or exposed to a wet or dry environment.
Voice recognition technology: low cost, fast access, applicable strict requirements.
Voiceprint is the acoustical spectrum of speech information displayed by electroacoustic instruments. It is ideally suited for remote identity verification and requires just one microphone or phone for remote login via the Internet (via a communications network or the Internet). However, the shortcomings of voiceprint identification is also very obvious, very demanding on the environment, in a noisy environment, mixed voice is not easy to obtain voice; people's voice will be with age, physical condition, age, emotions, etc. Changes; different microphones and channels have an impact on the recognition performance and so on.
Fingerprint recognition, face recognition, voice recognition, each have their own advantages and disadvantages of the application will inevitably be a problem, but as the market continues to expand, the technology continues to mature, I believe that biometrics will be the Internet, the Internet of Things intersection, as the Industry new focus.
