With the development of artificial intelligence technology, various biometric technologies are slowly showing up in our lives. From mobile phone unlocking, online payment to online banking fingerprint recognition or swiping face login. What are the main biometric technologies? What are the characteristics?
When you go to the bank for business, in the final confirmation link, the teller will ask you to sign on the tablet for confirmation. Signature recognition is based on the signature font for identity authentication, which is a traditional verification method, which was not a biometric technology at the time.
Signature recognition
Everyone has their own unique writing specifications, so signature recognition can be used as a kind of biometric identification and belongs to behavior measurement. Digital signature is a process of measuring the image itself and the entire signature action, including the speed, sequence and pressure of each letter and letter.
Signature recognition includes offline signature recognition and online signature recognition. Online recognition is to collect the author's signature sample through WordPad. Some systems can also collect data such as pressure and pen holding angle. However, since the dynamic setting of human writing is not fixed and has a certain range of changes, it may not be possible to distinguish real signatures from forged signatures only from glyphs.
Voiceprint recognition
Voice recognition is also a behavior recognition technology, but sometimes voice recognition is not as safe as signature recognition. Voice recognition is based on the exact match between the voice collected on site and the registered voice template. It relies on voiceprint recognition equipment to continuously measure and record the waveform and changes of the voice to confirm the identity of the other party.
The advantage of voiceprint recognition is that voice recognition is a non-contact recognition technology that users can actively accept. But there are also many shortcomings, for example, the range of sound changes is too large to match accurately. For example, when the user catches a cold and the vocal cord is damaged, it is difficult for the identification system to identify the user.
Iris recognition
We often see the protagonists in some technology movies use iris recognition to verify their identity. Iris recognition technology is a recognition technology based on biometrics. It scans through the iris of a person's eye through infrared scanning, and extracts features for sample comparison to confirm the identity of the other party.
Before iris recognition, it needs to locate parameter features. These features and unique shapes are used to image, separate and lift the iris. High precision and no physical contact are its advantages. This is why banks and other financial institutions use iris recognition to verify user ID.
As one of the mainstream biometric methods, the biggest advantage of face recognition is that there is almost no emphasis on hardware, and even a few hundred yuan mobile phone camera can be satisfied, and the rest is only a software problem. When you check out, take a look at the face-swiping device and the payment is complete. This authentication method has high convenience in the future mobile payment era, and has very low hardware requirements.
Fingerprint recognition is currently the most widely used biometric technology and has a solid market foundation. Fingerprint recognition technology can effectively confirm a fingerprint by analyzing the global and local characteristics of fingerprints, such as ridges, valleys, end points, and bifurcation points. Human identity. The feature value extracted from the fingerprint can be very detailed.
In the future, biometric technology will become a major development trend in the artificial intelligence industry. Many people worry that biometrics is not safe enough. After all, we need to use biometric technology to protect personal privacy and property security. What are the main applications of biometric technology? What are the advantages of biometric technology?
What is biometric technology?
The so-called biometric technology is to use the inherent physiological characteristics of the human body (such as human face, iris, veins, etc.) and behavior characteristics (such as handwriting, voice, gait, etc.) through computers and high-tech means such as optics, acoustics, biosensors and biometrics. The principles are closely integrated to carry out personal identification.
In which areas is biometric technology applied?
Mobile payment market
Taking mobile devices such as mobile phones as the representative, in recent years, most of the new mobile phones released by mobile phone companies have launched products and applications with biometric identification functions. The mobile payment market is a market where biometric technology is widely used. It is a well-known biometric application market. At present, many online consumers open fingerprint payment methods to quickly complete the payment process, and some people will not be difficult to complete the payment process because they forget their passwords. Paid. The rapid popularity of smart phones has greatly promoted the outbreak of the biometrics industry.
Attendance market
The traditional attendance market is basically occupied by fingerprint recognition technology. However, with the development of other biometric technologies, face recognition and vein recognition have gradually integrated into the attendance market due to their non-contact and long-distance advantages.
Smart door lock
Door locks are one of the consumer markets with huge potential for biometric technology. Especially in recent years, smart door locks using biometric technology have begun to slowly replace traditional locks. According to statistics, more than 80% of urban users in my country need to install smart door locks, and the market size of smart door locks exceeds 300 billion yuan. Smart door lock products are mainly based on technologies such as fingerprint recognition and face recognition. The popularization of iris smart locks in the future will bring convenience to users with high security needs.
During the epidemic, some high-traffic places such as train station entrances and exits, communities, schools, etc. are equipped with biometrics and infrared thermal imaging human body temperature measurement systems, which can detect the body temperature information of people entering and leaving, and identify the identity information of the other party.
As the country's requirements for real-name systems become higher and higher, biometric technology that "can quickly verify one's identity" will surely win the favor of relevant government departments. In fact, with the development of biometric technology, the application of biometric technology will no longer be limited to the above-mentioned fields. Any place that requires identity authentication and identification will be included in the biometric technology market. Like: residential communities, financial industry, education industry, social security and other fields have very broad application space, so the future biometric technology market will not be underestimated.
