? The so-called biometric technology is to use the inherent physiological characteristics of the human body (such as fingerprints, face images, irises, etc.). ) and behavioral characteristics (such as handwriting, voice, gait, etc. ) Identify individuals through the close combination of computers and high-tech means such as optics, acoustics, biosensors and biostatistics. Biometric identification technology mainly refers to a technology of identity authentication through human biometrics. Biometrics are usually measurable or automatically identified and verified, which is hereditary or lifelong. Therefore, biometric identification technology has great advantages over traditional authentication technology.
? Biometric identification system samples biological features, extracts their features and converts them into digital codes, and further composes these codes into feature templates. Because the cost of microprocessor and various electronic components is decreasing and the accuracy is gradually improving, biometric system is gradually applied to commercial authorization control, such as access control, safety certification of enterprise attendance management system and other fields. Biometric features used for biometric identification include hand shape, fingerprint, iris, retina, pulse, auricle, etc. Behavioral characteristics include signature, voice, key strength, etc. Based on these characteristics, people have developed many biometric technologies, such as hand shape recognition, fingerprint recognition, face recognition, voice recognition, iris recognition, signature recognition and so on.
? Our personal biometric information will be collected more or less, such as camera shooting, fingerprint collection and voice recognition? We will inevitably be collected by various forms of information. The most important thing is that the state has introduced relevant normative measures. At the same time, we should also pay attention to our own information, and don't post it on the Internet at will, so that criminals can take advantage of it.
