Research And Implementation Of Sensitive Data Protection System Based On Android

With the popularity of intelligent mobile terminals based on Android platform,the ability to make sensitive information security has been much criticized.The open source of Android platform and third-party application have make Android mobile intelligent terminal with a problem of personal privacy information leakage,and the issue of security has been questioned.The Android is based on Linux and sandbox mechanism and privilege mechanism on the basis of the existing Linux security mechanism are formed.However,the lack of open source and security mechanism has become the source of privacy information leakage.Research on Android system security has always been a hot topic for Android developers.Based on the above reasons,this paper analyzes and implements the sensitive information protection system based on the Android system from the rights management,privacy space,anti-reverse analysis.The following are the main job:This paper proposes a privilege management mechanism based on Android 6.0 or above.The software can only be installed when the user accepts all permissions requested in Coarse-grained permissions management mechanism.This paper puts forward a new scheme of privilege management based on the new features of Android 6.0 or above.According to different circumstances,the dynamic permission management pop-ups system Dialog prompt box and accepts the user's choice when the software is running.The APP runs with the user's wishes.According to the mainstream protection function of security software.A wide field sensitive information protection scheme is designed and implemented based on Android.The scheme mainly provides the encrypted storage of sensitive data,including contacts,videos,files and pictures,as well as application page locks and program locks.The scheme mainly lies in the protection of sensitive information,through the encryption and decryption of sensitive information.Through the program,the user can protect the sensitive information according to their wishes.Design and implementation of an anti-reverse scheme based on Android platform.The program is mainly from the application level to enhance the protection of the application,through the code obfuscation,anti-reverse analysis to enhance the application's ability to reverse.This paper is about design and implementation of a wide range,multi-level sensitive information protection system based on Android platform.In the core layer,the right and private space based on Android6.0 and above protect the data.The protection of the system is increased through the page lock,the program lock and the anti-reverse analysis.It is protecting private contacts,videos and pictures and other sensitive information according to our wishes that enhances the system's ability to protect specific data and prevent the disclosure of private data.The test shows that the sensitive information protection system proposed in this paper can realize the related functions and improve the security of Android system.
