Problems solved by technology

[0004] The fingerprint data entered by the mobile terminal is usually stored locally on the mobile terminal. If criminals steal the mobile terminal, they can use program cracking and physical attacks to steal the user's fingerprint data locally from the mobile terminal for decryption, payment, etc. operation, leading to the leakage of user information, and even property loss, with low security

Abstract

An embodiment of the present invention provides a mobile terminal. The mobile terminal is configured with a processor and a secure chip. The processor is provided with a virtual secure kernel and a virtual non-secure kernel; a secure domain is run in the secure kernel, a non-secure domain is run in the non-secure kernel, and the secure domain is accessed to the secure chip; and a first fingerprint template fragment is stored in the secure domain, a second fingerprint template fragment is stored in the secure chip, and the first fingerprint template segment and the second fingerprint template segment belong to the same fingerprint template data. According to the mobile terminal disclosed by the embodiment of the present invention, the deep security architecture of the non-secure domain, the secure domain, and the secure chip is constructed in the mobile terminal, if the hacker wants to crack the mobile terminal and obtains the fingerprint template data, the secure domain and the secure chip need to be cracked at the same time, and the security level of the secure chip can reach the EAL5+ security level, so that the program crack and physical attacks can be effectively resisted; and the self-destruction mechanism can be configured, so that the crack behavior by the hacker can be effectively prevented.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a mobile terminal. Background technique [0002] With the development of mobile communication technology, mobile terminals such as mobile phones are becoming more and more popular, which brings great convenience to people's life, study and work. [0003] Because fingerprint data can play a convenient protection function, eliminating the trouble of manually entering passwords, many mobile terminals enter the user's fingerprint data, and directly perform decryption, payment and other operations after verifying the fingerprint data. [0004] The fingerprint data entered by the mobile terminal is usually stored locally on the mobile terminal. If criminals steal the mobile terminal, they can use program cracking and physical attacks to steal the user's fingerprint data locally from the mobile terminal for decryption, payment, etc. Operation, leading to leakage of user i...
