Data protection technology based on operation redirection has not been implemented in Android operating system.To achieve the goal of operation redirection, the research of Android storage subsystem needs to be done.By modifying the block device driver and rebuilding the kernel, all block device I/O requests are monitored and redirected.The experiment results demonstrate that the redirection-based storage protection is feasible in Android system.The potential improvement is discussed at the end of the paper.
