Biometric security, worry, physical password or security key

Biometric identification refers to the technology of personal identification using the inherent physiological characteristics of the human body through computer and optical, acoustic, biosensor and biostatistical principles, mainly fingerprint recognition, speech recognition, face recognition. , iris recognition and other technologies. Today, with the development of intelligence, biometrics are becoming more and more popular, but at the same time, security issues have also raised concerns.

From voiceprints, fingerprints, faces, irises to veins, biometrics has opened up a rapid development model as application scenarios become more abundant. According to industry insiders, the biometrics market is expected to maintain rapid growth in the next few years. It is estimated that by 2020, the global biometrics market will exceed 25 billion US dollars, and the domestic market will exceed 30 billion yuan.

Development of various types of biometrics

With the rapid spread of smartphones, the biometrics industry is experiencing an explosive growth period. Since the Apple 5S uses fingerprint recognition, fingerprint recognition has now become the standard configuration for many domestic low-end mobile phones. Data show that in 2015, the penetration rate of fingerprint recognition reached 25%. It is estimated that by 2016, the fingerprint recognition penetration rate will reach 50%, and it is expected to exceed 70% in 2020.

Following the application of fingerprint recognition technology, iris recognition is expected to become an important configuration for smartphones. According to industry insiders, the texture information of the iris is much higher than the information of the fingerprint, and the theoretical accuracy is higher. The fingerprint recognition error rate is one in 100,000, and the iris recognition error rate can reach one ten-thousandth of a million; and the interference factor is less and the security is higher. At present, iris recognition technology has also been applied in the fields of finance, medical care, security, security and so on.

In the huge consumer market, face recognition technology is also brewing changes. According to data released by market research firm AcuityMarketintellience, the global biometrics market reached $7.339 billion in 2013. Among them, fingerprint recognition technology has the widest range of applications, with a market share of approximately 58%; followed by face recognition products, accounting for approximately 18%.

According to industry insiders, with the rapid advancement of fingerprint, face and iris recognition applications, other types of biometric applications such as voiceprints and veins will follow. However, different biometric technologies have their own advantages and disadvantages. For example, face recognition technology has a lower threshold, and fingerprints are unique and lifelong. Therefore, the combination of multiple biometric methods will be the future development direction of smart security technology.

Biometric technology security concerns

With the development of high technology, biometrics technology has been widely used as a new biometric authentication method, and gradually began to replace digital passwords. But is biometrics for safety really safe?

In this regard, experts frankly said, "Compared to existing methods such as digital passwords, biometrics have the advantages of good anti-counterfeiting performance, strong privacy, and 'carrying with you'. It is definitely a safer technology." However, existing Biometrics are not fully mature. At the physical level, it may be maliciously “copied” because of personal data abuse; technically, existing technologies require more security verification.

Nick Stephens from the University of California, Santa Barbara also said that including iris recognition, face recognition, fingerprint recognition, the biometric technology's security performance is almost the same, as long as the system has loopholes, can be broken. Stephens's statement is not sensational. On the "GeekPwn" geek carnival, he performed a "magic" to crack fingerprint recognition.

But at the same time, experts also said that they don't have to worry too much about the security vulnerabilities of biometrics, because the system vulnerabilities that these geeks break through will be submitted to hardware or software vendors to optimize existing systems and provide further development and security for biometrics. Support, and all users need to do is consciously protect their "body password."
