In recent years, the accuracy of microprocessors and various electronic components has been improved year by year. Biometric technology has been gradually applied to the field of smart home, which has brought convenience to people's life. At the same time, it has been widely used because of its good security

before starting, I will briefly popularize the science. Biometric technology is a technology that uses the inherent physiological characteristics of the human body (such as fingerprint, face, iris, etc.) and behavioral characteristics (such as handwriting, sound, gait, etc.) to identify individuals through the close combination of computers and high-tech means such as optics, acoustics, biosensors and biostatistics

human biometrics usually have the characteristics of uniqueness, measurable or automatic identification and verification, heredity or lifelong stability. In recent years, due to the continuous decline in the cost of microprocessors and various electronic components, and the improvement of accuracy year by year, biometric technology has gradually been applied to the field of smart home, which has brought convenience to people's lives. At the same time, it is also widely used because of its good security. What are the main biometric technologies applied to the smart home industry

first, fingerprint recognition

fingerprint refers to the uneven lines on the front skin of the end of human fingers. The lines are regularly arranged to form different patterns. Fingerprint has almost become a synonym for biometric recognition because of its lifelong invariance, uniqueness and convenience

fingerprint recognition technology is the most mature and low-cost biometric recognition technology at present. It is widely used in the field of smart home, and its most typical application is smart lock

second, voice recognition

voice recognition is a technology that recognizes by analyzing the physical characteristics of users' voices. At present, the largest application in the field of smart home is smart speakers

however, due to low recognition accuracy and false wake-up, it is not convenient to use at present, mainly because of the great variability of the sensor and human voice. At present, a lot of research work is still in progress. Xiaobian believes that voice recognition technology will make greater progress in the future

III. face recognition

face recognition is also called face recognition, face recognition, etc. face recognition uses a camera as a recognition information acquisition device to obtain the face image of the recognition object in a non-contact way. The computer system completes the recognition process after obtaining the image and comparing it with the database image

the application of face recognition in smart home is mainly intelligent security system. The face recognition system compares, analyzes, identifies and confirms with the face information data stored in the background after capturing the face image through the camera recognition device. When a stranger enters the security field and is captured by the camera, the system will notify the owner and make a video recording

the above three biometric technologies are currently widely used in the field of smart home. Through the application of the above technologies, it is greatly convenient for special people to use smart home (such as the elderly, children, etc.), and expands the scope of application of smart home. I believe that with the development of related technology, the smart home will become more and more smart in the future
