The Design Of File Safe For Android Mobile

Android is Google’s mobile operating system, as a strong intelligentterminal system, it is very popular among users. With the rapid development of smartphone, as a very important tool for communication in real life, the function of smartphone is becoming more and more powerful, also there are more and more widelyapplication. Followed by mobile phone security issues are also increasingly prominent.Because of the characters of open source, programmable software framework andnetworked devices, the Android phone is vulnerable to smartphone virus attack, inwhich the property of privacy to steal malicious software was front. And a largeamount of users’ personal privacy information were stored on mobile phone, so theprotection for user privacy information and secret documents is becoming more andmore valued.For the security problems of Android phone users’ personal information andprivacy secret files, this article proposed the design of Android file safe.This paper analyzes the present situation and future development trend ofsmartphone, and hidden danger existing in the Android phone, and analyzes Androidsecurity mechanisms, and Android mobile phone privacy security problem andprotective measures. The design was developed on the development environmentbased on the Android platform, and through the JNI technology to make the Java and Cinteract, to improve the application efficiency. Based on the demand analysis andstructure of the Android file safe, the paper expounded the system’s overall functionstructure and system design. The system design mainly includes the user access control,file backup protection, safe, etc. And according to the function module to do the designin detail and implementation, finally the application was tested through the emulator,realized the function of protection for the users’ personal important information storedon mobile phone and backup, which can effectively protect the cell phone user’spersonal privacy information and important files.
