Security chip, authentication method based on biological features and intelligent terminal

Abstract

The invention provides a security chip which comprises a storage unit, a relation establishing unit and a judging unit. The storage unit is used for storing biological feature information of an operator with operation authority, the relation establishing unit is used for establishing the corresponding relation between the biological feature information and the operation authority of the operator, and the judging unit is used for judging whether the biological feature information for requesting for the operation authority corresponds to the operation authority or not. The security chip independently stores and verifies the corresponding relation between the biological feature information and the operation authority, an intelligent terminal process does not store the biological feature information, and the probability that the biological feature information is stolen by lawbreakers is greatly reduced; the security chip can independently carry out the authentication service of the biological features collected subsequently, the intelligent terminal process does not need to participate, the probability that an authentication system is damaged by malicious software, wooden horses and viruses is greatly reduced, and information security is greatly improved. The invention further provides an authentication method based on the biological features and an intelligent terminal capable of achieving authentication based on the biological features.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a security chip, an authentication method based on biometric features and an intelligent terminal. Background technique [0002] With the development of science and technology, the penetration rate of electronic equipment is getting higher and higher, and smart terminal equipment has become an indispensable part of our daily work and life. Mobile smart terminals, vehicle-mounted smart terminals, smart TVs, smart wearable devices, etc. bring great convenience to our work and life, and greatly improve our work and living standards. [0003] However, as smart terminal devices are more and more deeply integrated into our work and life, from simple entertainment to complex information processing, from initial bank account information viewing to remote payment involving high confidentiality and high security, mobile Payment, whether the information security of smart termi...

Problems solved by technology

Although this method improves the security of mobile payment, in the process of payment execution, the transmission, storage and authentication of fingerprints are all carried out in an ordinary software and hardware environment, which may be attacked by malicious software, Trojan horses and viruses. The possibility of fingerprint information may also be stolen by criminals, there is still a greater risk
