Problems solved by technology

Although the dynamic link library is not easy to be deciphered by malicious programs, since the JNI interface in the Android code cannot be confused, the malicious program can still obtain the JNI interface and directly call the dynamic link library. Sensitive data, still low security
[0004] Chinese patent application CN201510259122.7 discloses a security enhancement method for Android smart TV sensitive data, which encrypts the virtual file system by using a key system related to hardware unique information, and strictly binds the decryption key to the device , to prevent attackers from transplanting sensitive data storage files or APK files to other devices for execution, thereby enhancing the security of sensitive data on Android smart TVs. However, this method has high requirements on the hardware conditions of the terminal and cannot be widely used. use

Abstract

Embodiments of the invention provide an application program data protection method and device. The method comprises the steps: receiving a request command aiming at data of an application program; by aiming at the request command, invoking a JAVA local interface; acquiring dynamic signature value of the application program by utilizing the JAVA local interface; judging whether the request command is a trustable command according to the dynamic signature value. Therefore, according to the application program data protection method and device, addition of asymmetric encryption mechanism based on a unique signature of the application program is implemented, and the security of the data of the application program is ensured.

Description

technical field [0001] The present application relates to the technical field of information security, in particular to an application data protection method and an application data protection device. Background technique [0002] With the development of technology, smart terminals such as smartphones and smart TVs have increasingly become an indispensable part of people's lives. Various applications on smart terminals present a rich and colorful world to people. Through applications, people can easily realize activities such as obtaining information, watching entertainment programs, purchasing commodities, and completing payment. Just because the functions of the application programs are becoming more and more powerful, people pay more and more attention to the data security of the application programs. [0003] Take the Android Android class application program as an example. Due to the open source nature of Android, the code of Android applications is extremely easy to ...
