Abstract

The embodiment of the invention provides a data protection method and a data protection device of movable storage equipment and the movable storage equipment. The data protection device comprises a triggering unit, a power supply unit and a processing unit, wherein the triggering unit is used for emitting a power supply request signal and an elimination request signal when the movable storage equipment meets a preset data protection triggering condition; the power supply unit is used for receiving the power supply request signal emitted by the triggering unit and supplying power to the processing unit and a storage unit of the movable storage equipment; and the processing unit is used for receiving the elimination request signal emitted by the triggering unit and eliminating data stored in the storage unit. In the embodiment, a certain triggering condition is preset in the movable storage equipment; if the condition is met, the power is supplied to the movable storage equipment and the data stored in the movable storage equipment are eliminated, therefore, the problem of leaking the data after the movable storage equipment is filched is avoided and the safety of information stored in the movable storage equipment is ensured.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of mobile storage, and in particular, to a data protection method and device for a mobile storage device and a mobile storage device.
