Embodiment Construction

[0041] The technical solutions of the present invention will be further described in detail below through specific embodiments.

[0042] Embodiments of the present invention provide a method for preventing leakage of application data, such as figure 1 As shown, the method includes the following steps:

[0043] In step 100, a host program is installed on an intelligent terminal, the intelligent terminal has a security module embedded or externally inserted, and the identification code of the host program and the identification code of the security module are bound.

[0044] Preferably, the host program is an application management system implemented in the form of software, which is used to intercept and proxy system services on the intelligent terminal, install, call, monitor and manage target applications, and perform security checks on security The module function is called.

[0045] The security module is used for key generation, encryption and decryption, and identity ve...

Abstract

The invention discloses an application data leakage preventing method and apparatus. A host program and a use security module are installed in an intelligent terminal; system services are interceptedand agented through the host program; installation, calling, monitoring and management of a target application are realized; hardware encryption is realized through a security module; different keys are allocated for data files of the target application, and encryption and decryption of the keys are finished; and transparent encryption and decryption of data are realized by using particular keys for the data files needed to be encrypted. The target application accesses the data files only through the host program bound with the security module, so that the target application is enabled to runin a tight secret running space, and the data of the target application only can be used in the secret running space. According to the technical scheme, application data leakage is prevented more effectively, so that the application data has higher security.

Description

technical field [0001] The present invention relates to the technical field of application programs, in particular to a method and device for preventing leakage of application program data. Background technique [0002] The leakage of user data is an important aspect of information security. When users use smart terminals, applications and Trojan viruses may leak user data, causing privacy leakage and property losses to users. For state organs, enterprises and institutions, in order to protect the security of business data and confidential information, the data leakage prevention measures of smart terminals need to prevent information leakage caused by system loopholes and external attacks on the one hand, and prevent employees from improperly on the other hand. The leakage caused by the operation puts forward higher requirements for the intelligent terminal data leakage protection system. [0003] Using the sandbox technology, on the basis of the local operating system, t...
