Security authentication method and terminal

Abstract

The embodiment of the invention discloses a security authentication method and a terminal. The method comprises the steps of determining a security level of terminal authentication according to usage scenario of the terminal, wherein the usage scenario comprises the distance between the terminal and a user or an application type corresponding to the terminal authentication; and starting different security authentication mechanisms according to the security level of the terminal authentication. The terminal comprises a determining unit for determining the security level of the terminal authentication according to the usage scenario of the terminal, wherein the usage scenario comprises the distance between the terminal and the user or the application type corresponding to the terminal authentication; and an authentication unit for starting different security authentication mechanisms according to the security level of the terminal authentication. According to the method and the terminal provided by the embodiment of the invention, the information security of the user can be improved, and the information security demand of the user can be satisfied.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to a security authentication method and a terminal. Background technique [0002] With the popularization of terminal devices such as mobile phones and pads, users can use the terminal for information exchange, online payment, etc., and the terminal has become an important communication tool for today's communication. The information security on the terminal and the information security of the terminal communication are becoming more and more important. [0003] As a method of security authentication, fingerprints are widely used in many scenarios, such as fingerprint recognition to boot, enter specific applications, and make online payments. At present, most fingerprint identification algorithms are matching algorithms based on minutiae features, that is, as long as the fingerprint minutiae features can reach a predetermined matching degree, the verification c...

Problems solved by technology

At present, most fingerprint identification algorithms are matching algorithms based on minutiae features, that is, as long as the fingerprint minutiae features can reach a predetermined matching degree, the verification can be completed. This verification method is safe and efficient enough, but with the rapid development of high technology, Some hackers can easily steal the user's complete fingerprint information, so the traditional fingerprint authentication method will not be able to meet the user's security needs

On the other hand, when performing authentication, an appropriate authentication method is not selected according to different terminal usage scenarios. For example, for some applications with a higher security level, using the same authentication method as an application with a lower security level cannot guarantee information security
