Authentication method for mobile terminal and mobile terminal

A mobile terminal, wherein the mobile terminal comprises one or more processors, a memory, multiple application programs, and one or more programs, wherein the one or more programs are stored in the memory and executed by the one or more processors, wherein the one or more programs comprise an instruction, and wherein the instruction is used to perform the following operations:

• running, by a first application, in a first execution environment;
• running, by a second application, in a second execution environment, wherein the second application is associated with the first application;
• running, by a biometric feature management module, in the second execution environment, wherein the biometric feature management module is configured to perform, in the second execution environment, an operation related to biometric feature authentication;
• generating, by the first application, a request message, wherein the request message carries identification information of the second application or the biometric feature management module;
• sending the request message to an interface of the second execution environment by using an interface of the first execution environment;
• and
• if the request message carries the identification information of the second application, sending, by the interface of the second execution environment, the request message to the second application;
• or
• if the request message carries the identification information of the biometric feature management module, sending, by the interface of the second execution environment, the request message to the biometric feature management module.

• receiving, by the second application, the first request message by using interfaces of the first execution environment and the second execution environment;
• and
• if the second application determines that the first request message is a request message related to a biometric feature, sending, by the second application, the first request message to the biometric feature management module.
