What Are Biometric Devices?

The so-called biometric technology is the close combination of high-tech means such as optics, acoustics, biosensors, and biostatistics through computers, using the inherent physiological characteristics of the human body (such as fingerprints, face images, iris, etc.) and behavior characteristics (such as handwriting , Voice, gait, etc.) for personal identification.

Biometrics

So-called

The so-called biometric technology is to use a computer to communicate with

Traditional identification methods include identification items (such as keys, certificates, ATM cards, etc.) and

Biometric technology mainly refers to human biometrics.

Because human characteristics have the irreproducible uniqueness inherent in the human body, this creature

Many biometric technologies have appeared today, such as fingerprint recognition, palm geometry recognition, iris recognition, retinal recognition, face recognition, signature recognition, voice recognition, etc., but some of them are still in the experimental stage with high technical content. We believe that with the rapid progress of science and technology, more and more biometric technologies will be applied to real life.

Biometric technology can be widely used in government, military, banks, social welfare, e-commerce, security defense. For example, a depositor walks into a bank and makes a withdrawal without a bank card or a password. When he withdraws money at a cash machine, a camera scans the user's eyes and then quickly and accurately Has completed user identification and completed the business. And the sales department is using the "iris recognition system" in modern biometric technology. After the September 11 incident in the United States, anti-terrorist activities have become the consensus of all governments, and it is very important to strengthen the security of the airport.

Biometric Visa Application

Biometric technology mainly refers to a technology for identity authentication through human biometrics. The biometrics here usually have unique (different from others), can be measured or can be automatically identified and verified, heritable or unchanged for life. , Including fingerprint recognition, vein recognition, iris recognition, retinal recognition, facial recognition, DNA recognition, etc. Among them, fingerprint recognition, vein recognition, iris recognition, and facial recognition are widely used in the security field. According to the latest news, in order to meet the needs of the development of the situation, China will introduce biometric technology in time to introduce biometric visas. The application of biotechnology in the field of visas not only improves the quality and level of visa issuance, but also improves the anti-counterfeiting performance of visas. Relevant industry insiders said that while ensuring the security of the country and citizens, it is necessary to do a good job in protecting the entry and exit of normal personnel. Technical changes in visa carriers and identifiable information are imperative.
Biometric visa is a new trend in the development of visa technology in the world. Especially after the September 11th incident, countries such as the United States, Britain, and France began to issue biometric visas to foreign citizens while issuing electronic passports with biometric information for their citizens. This technology is being accepted by more and more people. The so-called biometric visa refers to the introduction of biometric technology into the visa field. It uses biometric features such as facial features and fingerprints to be safe and confidential. It collects and stores biometric information and data during the process of issuing visas or entering and exiting border inspections. Yes, it is more accurate and faster to identify the immigration personnel. At present, relevant supporting regulations have been discussed and formulated, and related technical and R & D work has begun preparations. China's biometric visa is worth looking forward to. ^[6]

Biometrics punch-in application

"Punch" application is the use of biometric iris recognition technology. According to statistics, this technology has been applied in many fields such as mine safety production, prison inmate management, bank vault access control and other fields. As long as the eyes are pointed at the screen, the machine writes down the iris feature password and completes the registration process. After the recognition process, the person with eyes can remove the glasses. Just aim at the screen for a while, less than one. In seconds, the machine has completed the comparison and identification, and the identity information and "check-in" time are immediately displayed on the screen.
This iris recognition technology has now been applied in the fields of Chinese coal miner attendance, prison inmate management, bank vault access, border security clearance, military security system, and candidate identification verification. The iris recognition products independently developed by the Chinese Academy of Sciences have been registered and used by nearly one million users in more than 20 provinces and cities, and billions of iris comparisons are completed every day, accounting for 70% of the domestic iris recognition market.
From short-distance recognition to long-distance recognition, from the recognition of stationary people to the recognition of moving people, and then to the recognition of a large number of people, the development of iris recognition has clearly mapped the roadmap of scientific research. Imagine the ubiquitous life of biometrics in the future: the key is no longer necessary, as long as you give a look, the door of the house can be opened for you; you can withdraw money at the bank without having to bring a card, swipe your face, or worry about account theft; When a stranger comes, the video surveillance will immediately sound an alarm; online shopping, just look at the camera, you can realize the payment and flow of funds; log in social networks, you can instantly find all the photos of the network of friends on the same face; Based on the results of face analysis, the owner of the supermarket can count the number and age distribution of customers that day, and use it to analyze sales. Advertisers can also provide more targeted advertisements accordingly. People who want to carry out criminal activities such as theft also If you weigh it well, there is no possibility of forgery, and there are ubiquitous cameras that can quickly "spoof out" bad elements. ^[7]
