A New Approach for Data Protection in Case of the Physical Device Being Stolen-Using Hybrid Storage
Flash memory, favored by its high speed, low power dissipation and excellent kinetic shock resistance, is a type of memory widely used in USB mass storage devices. Compared with the data stored in Hard Disk Drive (HDD), which can be easily recovered, data stored in Flash memory is hard to be recovered once erased, and this feature is more beneficial to data security. Under such circumstances, it might be a solution to mix Flash with HDD. Taking into consideration the characteristic that data stored in Flash memory is hard to be recovered once erased, this paper designs a system mixing Flash memory with HDD. It avoids the cracker get the whole plaintext by storing key data, which can be erased when necessary, in Flash.
