Embodiment Construction

[0023] The application of the present invention is illustrated by taking an Android smart phone as an example.

[0024] The Android system is divided into four levels: Applications (application layer), Application Frameworks (application framework layer), Libraries and Android Runtime (class library and real-time runtime library layer), Linux Kernel (Linux kernel layer).

[0025] 1. Applications (application layer)

[0026] Android will pre-install a set of core applications, including email client, SMS service, calendar schedule, map service, browser, contacts and other applications. All applications are written in the Java programming language.

[0027] At the application layer, all applications that store information based on files can implement dynamic encryption and decryption protection for files operated by the applications by calling the API provided by the interface module of the present invention.

Abstract

The invention provides an information security protecting system and method of a mobile terminal. The system comprises an interface module, a security policy setting module, a file access controlling module, a file access log recording module and a dynamic encrypting / decrypting module. The interface module provides an API (Application Program Interface) for being called. The security policy setting module can set a corresponding security policy according to a command sent by the interface module. The file access controlling module realizes controlling of access operation to file objects in the mobile terminal. The file access log recording module realizes recording of all operations to files. The dynamic encrypting / decrypting module is located at a kernel layer of a mobile operating system and realizes encrypting / decrypting treatment to the files according to the set security policy. The system and the method provided by the invention can be applied to mobile terminals which take a file as an information storage manner so as to provide encrypted protection; and in addition, the invention has the advantages of comprehensive protection, strong expandability, high security, low occupancy of system resource and good user experience.

Description

technical field [0001] The invention relates to a mobile terminal information security protection system and method. Based on the dynamic encryption and decryption technology at the kernel level of the mobile operating system, various applications of the mobile terminal can be encrypted and protected to avoid leakage of information stored in the mobile terminal. [0002] Abbreviations and explanations: [0003] API: Application Programming Interface [0004] PIN: The full name is Personal Identification Number, which is the personal identification password of the SIM card of the mobile terminal. [0005] SD card: The full name is Secure Digital Memory Card, translated into Chinese as a secure digital card. It is a storage device based on semiconductor flash memory. It is widely used in portable devices, such as mobile phones and digital cameras. Background technique [0006] With the continuous popularization of smart mobile terminals (including smart phones and tablet com...
