Abstract:

As mobile devices of Android are becoming very prevalent, more and more personal privacy data is stored in the Android mobile terminal. Due to the openness of Android, lots of malicious programs are attacking the system, which result in problems of privacy data leakage. Private data protection is necessary to be resolved. This paper designs and implement a kind of Android security data storage platform, which used a key protection scheme with the collaboration of Android APP and cloud server. Simultaneously, the technology of key split and multiple-key system is used to ensure the security. The platform can ensure the data security storage based on the above. The Third-party APP can store privacy data securely in the terminal through this platform. Also user can login cloud server to control of all privacy data in Android, which shows a very high security and scalability.

Key words: key protection, Android, cloud server, key split, data storage
