With the rapid development of Android systems and the growing of Android market, Android system has become a focus of the developers and users, but at the same time, the problem of data security along with the Android system such as malware, privacy leaks are also prominent. In this paper, we research the dm-crypt disk encryption technology, the mobile phone source code and the Android file system and propose a high efficiency encryption scheme of dual data partition for Android devices. We separate a part of storage space as the encrypted datapartition from the original datapartition and apply the dm-crypt disk encryption technology so that the encrypted datapartition is automatically mounted when Android system starts. In the encrypted datapartition, users can store their privacy data, and the data are stored encrypted datapartition of the cell phone after real-time encryption, so the scheme implement the storage protection and improve the security of the data storage of the Android system.
