Time based incremental backup scheme for mobile cloud computing

Abstract

A time-based data secure backup mechanism for moving the cloud was presented.Time was considered as a parameter into the data encryption for the important information in mobile device and backups the users' data ac-cording to the time period.It had not only solved the issue of the latest timely backup sensitive data,but also solved the entire ciphertext leak caused by missing the backup key.
