Today, biometrics technology has become a new generation of security and verification technology for people. Through the recognition of human physiological or behavioral characteristics, coupled with the help of cloud technology, big data, the Internet of Things, deep learning and other information technologies, biometrics Technology has shown a strong application value and role.
In life, the more familiar recognition technologies include fingerprint recognition and face recognition. They are widely used in mobile phone unlocking, mobile payment, traffic riding, security and access control, etc., and bring a lot of convenience to people. However, due to security issues, the current two are not living well.
Earlier this year, many media revealed that the scissors hand when we took pictures could leak fingerprint information, which led to the violation of personal privacy. At the same time, the outbreak of the APP "Zao" incident and the "first case of face recognition The emergence of "" also exposed the issue of identification security to the public.
The frequent emergence of the above-mentioned information security hazards has given people a new perspective on fingerprint recognition and face recognition, and "convenient and more secure" has gradually become the mainstream evaluation of both. In this context, the dominance of fingerprints and face brushing has been significantly shaken, and some new identification methods have quietly risen.
This includes voiceprint recognition!
So, what is voiceprint recognition?
Can voiceprint recognition replace fingerprints and brush your face and become the new mainstream in the "identification era"?
In fact, voiceprint recognition is a technology that recognizes a speaker by voice. This technology converts human voice signals into electrical signals and then uses a computer to identify them. The principle is that the voiceprint patterns produced by people are different because of different vocal organs such as tongue, throat and nose. With this acoustic feature, the identity of the speaker can be effectively confirmed and verified.
Many people may think that voiceprint recognition is a new thing that has just emerged, but in fact it is already an "old bird" in the field of biometrics. As early as the 1660s, the use of voice as a means of identity verification appeared in the trial of the death of Charles I in the United Kingdom; at the same time, in 1966, US courts also used voiceprints to obtain evidence. . .. . .
Since its development, voiceprint recognition technology has roughly developed in three stages. From the beginning, the same content was artificially compared to the sound image for identity matching. Today, it is blessed by artificial intelligence deep learning, and the computer easily analyzes the voice information to confirm the speaking Human identity and voiceprint recognition have made great strides in technology.
In terms of application, the development of voiceprint recognition is not too much to be desired. Compared with the more familiar speech recognition, the application space of voiceprint recognition is more extensive. If speech recognition focuses on "what is said" and can only be used for information confirmation, then voiceprint recognition focuses on "who is speaking", so there is an additional layer of identity verification.
Among them, the application of voiceprint recognition in the confirmation function can meet many security requirements such as online transactions, payments, and remote identity authentication. Therefore, in recent years, it has gained significant applications in bank transactions, voice-activated locks, and credit card identification. For example, China Construction Bank has used voiceprint recognition as a user identity authentication during network payments. At the same time, WeChat has also launched a login method based on voiceprint dynamic passwords to ensure the security of user accounts. In addition, some social security bureaus have also Use voiceprint recognition as a survival certification to prevent fraudulent and misclaimed social security amounts.
In terms of verification and identification functions, voiceprint identification technology is also often used in areas such as justice, criminal investigation, and national defense to maintain social stability and national security. For example, using voiceprint recognition to track suspects makes the arrest more convenient and efficient. It is reported that Osama bin Laden's arrest was inseparable from the application of voiceprint identification technology in the United States. Another example is the application of voiceprint recognition in criminal investigation. , Can effectively solve cases of intimidation, kidnapping and extortion; and, in military warfare, can also use voiceprint recognition technology to listen to enemy orders, thereby occupying the battlefield initiative.
All in all, based on voiceprint recognition, remoteness, accuracy, and higher security, it has more powerful application value and wider application space than general biometric technology. As the technology continues to mature in the future, voiceprint recognition is expected to land in more scenes, becoming another new identity ID after fingerprints and faces, making the role of sound more and more important in our lives.
However, it is not easy to realize this vision. At this stage, the reason why voiceprint recognition hasn't become mainstream is because the landing in the consumer field is not mature enough. The reason for this phenomenon is that the technology itself is difficult, the industry threshold is high, and the product levels of various manufacturers are uneven. It is also that the relevant standards and specifications are not perfect, the security guarantee of voiceprint recognition and the industry supervision are not mature enough, and the market has been tepid. In view of this, in the future, attention needs to be paid to both technology and regulations.
However, the cost and difficulty of sound collection is far lower than that of human faces and fingerprints, so the application of voiceprint recognition in password verification and identity confirmation is also more suitable and practical. In this context, the days when voiceprint recognition is slowly rising and rivaling fingerprints, faces, etc. may finally come, but the process may be slower, and we should be patient and expect it.
