Data processing method and terminal

Abstract

The embodiment of the invention discloses a data processing method and a terminal. The data processing method and the terminal are used for protecting information and property safety of a user. The data processing method in the embodiment includes the steps that a terminal detects a preset function command in a credible execution environment TEE, wherein the TEE runs on a coprocessor of the terminal; when the preset function command is detected, and a function module corresponding to the function command is controlled to be started; the coprocessor is controlled to process data collected by the function module to complete the corresponding function. In the embodiment, as the TEE runs on the coprocessor, an operation system (OS) runs on a main processor, the TEE running environment and the OS running environment are subjected to hardware insulation, hackers are difficult to make an attack to the TEE and difficult to seek the security vulnerability in the OS, and the information and the property safety of the user are protected.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a data processing method and terminal. Background technique [0002] As the functions of terminals become stronger and richer, more and more fields are used for terminals. For example, the most widely used terminal payment business and the clients of various shopping websites, these applications need to be linked with personal information and credit card information. Binding, therefore, more and more attention has been paid to terminal security issues. At present, security identification such as fingerprint verification is widely used in terminal unlocking, secure payment, private mode, dual system, etc. [0003] At present, the traditional security operations such as fingerprint security payment in the terminal are implemented in the trustzone built into the processor (Advanced RISCMachines, ARM). When the system is running, attacks are launched and security holes a...

[0003] At present, the traditional security operations such as fingerprint security payment in the terminal are implemented in the trustzone built into the processor (Advanced RISCMachines, ARM). When the system is running, it launches an attack and looks for its security holes. Once the fingerprint password and other information are stolen, the user's information and property security will be threatened.
