Do you know the pros and cons of biometrics?

The advantages of biometric technology
1. Improve social efficiency

Biometric recognition technology can accurately identify individuals by relying on the differences in physiological characteristics, saving people the time and energy of designing and recording traditional passwords. At the same time, fingerprint recognition, voice recognition, etc. facilitate people's lives.

2. Enhance insurance and reliability
Traditional passwords have risks of loss, theft, and deciphering, and the uniqueness and exclusivity of biometric identification make it impossible for illegal users to steal and crack the identification password, escorting personal information and property insurance. For example, the fingerprint path of the human body is unique, and the particularity of the pupil and iris shape will not be modified and copied, and the reliability of insurance and protection is high.
3. Avoid contact
Face Recognition, fingerprint recognition, voice recognition and other methods avoid traditional contact verification, which helps to protect public and personal hygiene and reduce the risk of disease transmission.
4. Combating illegal and criminal activities
Through the collection of biological information and the establishment of a database, the public security department can accurately identify the most troublesome according to the remaining biological information, which has brought great help to the detection of theft, rape, murder and other cases.
The disadvantages of biometric technology
1. Defects in biometric algorithms lead to high misrecognition rate
Considering the differences in the actual physiological state of individuals, various biometric information identification methods have problems of collection and identification in practice. For example, some people's fingerprints are damaged, and it is difficult to perform fingerprint recognition; factors such as face cosmetic surgery, damage, and poor adaptability to the environment lead to the failure of Face Recognition Attendance; it is difficult for cataract patients to perform iris recognition. In addition, deep fake biometric information is difficult to determine and trace, such as AI face-changing technology.
2. It is difficult to popularize technology
Traditional biometric technology relies on electronic information technology, big data computing, cloud storage and other technologies as support, and operates through the cooperation of multiple sets of software and hardware systems. Among them, the purchase, operation and maintenance costs of equipment are relatively high, which has brought certain obstacles to the popularization of biometric technology. Technologies such as iris recognition and vein recognition require a lot of computation, and the device recognition time is long and power consumption is high.
3. Insurance issues of biological information
Traditional account passwords, verification codes, etc. can be modified or retrieved, while fingerprints, facial features, iris, DNA and other information are subject to uniqueness and immutability. Once leaked, criminals may forge fake identity information, threatening To people's data, property insurance. Secondly, some biological information is easily obtained illegally from other channels and used by others, such as using sensor data without permission protection or using other forms of presentation attacks. Different devices have different levels of response to complex and changeable attacks. For example, in face recognition attendance, criminals use 2D rendering attacks and 3D rendering attacks to unlock applications. Different AI devices have huge differences in algorithm capabilities due to differences in algorithm capabilities. Insurance hazard.
In addition, the misuse of biometrics could affect National Information Insurance. With the advent of the era of big data, the government and other public service agencies have become important strategic resources for public information collection, calculation, analysis, storage, and management, and database insurance is also an important national insurance. Therefore, it is an important prerequisite and foundation for the large-scale application of biometric technology to do a good job in the protection of digital information systems and eliminate hidden dangers of information insurance such as data leakage.
