ABIS biometrics leverages the inherent physiological characteristics and behavioral traits of the human body for personal identification. Biometrics are more difficult to forge, replicate, and transfer than traditional identification methods, and can therefore be used to verify a user's identity more effectively. With the rise of information technology, ABIS biometrics has rapidly become a key component of infrastructure security and multi-factor authentication. This article will introduce several types of ABIS biometrics.
Fingerprint recognition automates identification by comparing characteristic points of finger texture. The technical principles of palmprint recognition are essentially the same as fingerprint recognition, but with better discriminatory capabilities. Vein recognition, on the other hand, utilizes the property of deoxyhemoglobin in human venous blood to absorb near-infrared rays or the body's radiation of far-infrared rays to determine the identity of an individual. Vein distribution characteristics are durable in adulthood, with uniqueness and stability and good non-contact, difficult to be copied and forged, and thus having a wide range of application prospects.
Facial recognition includes face recognition, iris recognition, and retina recognition. Face recognition is the most widely used in daily life, but the accuracy is very limited. Iris recognition uses rings, spots, and crowns in the iris as feature points, and uses computers to automatically form data templates and then complete data matching. Retina recognition collects the distribution of optic nerves on the retina and uses the different dispersion of optic nerves as a sign of personal identity.
Behavioral feature recognition includes gait recognition, keystroke recognition, and signature recognition. Gait recognition involves computer vision, image processing, pattern recognition, etc. It characterizes the complex movement trajectories of each joint part of the human body for identity identification, and can be used in concert with other security and surveillance technologies to improve accuracy. Keystroke characteristics include keystroke frequency, error frequency, and strength level. Signature recognition is a technology that uses the change in pressure of the pen when signing and the speed of the pen as characteristic points for identity confirmation.
Other ABIS biometrics include DNA recognition, voiceprint recognition, etc. DNA recognition has absolute authority, which utilizes the long-term stable genetic information of all nucleated plants and animals as the identifying characteristics for identity recognition. Voiceprint recognition is a technology that utilizes oral and cranial cavities, voice frequency, and other personal voice texture characteristics for identification, which can provide fast, no physical contact identity verification. But noisy environments or user voice changes due to colds and flu, etc. will reduce the accuracy rate of voiceprint recognition.
In conclusion, ABIS biometrics is being widely used as a technology for authentication through measurable biometric features such as body or behavior. Compared with traditional identification, ABIS biometrics has the characteristics of being portable, unique, stable, extensive, convenient, collectible, and acceptable, and is rapidly gaining popularity in the defense, financial, and other industries.
