1. Biometric technology. The so-called biometric technology is to closely combine computers with high-tech means such as optics, acoustics, biosensors, and biostatistics principles to use the inherent physiological characteristics of the human body (such as fingerprints, facial images, iris, etc.) and behavioral characteristics (such as handwriting) , voice, gait, etc.) to conduct personal identification.

According to the 2009 statistical results of IBG (International Biometric Group, International Biometric Group), there are many applications for different physiological and behavioral characteristics in the market. Among them, the one with the highest share is fingerprint recognition.

2. Biomedical Engineering (BME) is a combination of physics, chemistry, mathematics, computer and engineering principles, engaged in research on biology, medicine, behavior or health; it proposes basic concepts , generate knowledge from the molecular level to the organ level, and develop innovative biological products, materials, processing methods, implants, devices and informatics methods for disease prevention, diagnosis and treatment, patient rehabilitation, improvement of health conditions, etc. . Extended information

Biometric technology mainly refers to a technology for identity authentication through human biological characteristics. Human biological characteristics usually have the characteristics of being measurable or automatically identifiable and verifiable, heritable or unchanged throughout life. , so biometric authentication technology has greater advantages than traditional authentication technology.

The biometric system samples biological characteristics, extracts their features and converts them into digital codes, and further combines these codes into feature templates. As the cost of microprocessors and various electronic components continues to decrease and their accuracy gradually improves, biometric identification systems are gradually used in commercial authorization control such as access control, enterprise attendance management system security authentication and other fields.

Biological characteristics used for biometric identification include hand shape, fingerprint, face shape, iris, retina, pulse, auricle, etc. Behavioral characteristics include signature, voice, button strength, etc. Based on these characteristics, people have developed various biometric technologies such as hand shape recognition, fingerprint recognition, facial recognition, pronunciation recognition, iris recognition, and signature recognition.
