High-capacity data storage device and data destruction method thereof

Abstract

The invention discloses a high-capacity data storage device and a data destruction method thereof. The high-capacity data storage device comprises an interface module, a volatile storage module, a nonvolatile storage module, a trigger module, a processor and a power module; data transmitted by the interface module is mainly stored by the nonvolatile storage module, and the rest data is stored by the volatile storage module; by receiving the trigger signal sent by the trigger module, the processor controls the built-in power supply module to interrupt power supply to the volatile storage module, so that even if the data in the nonvolatile storage medium is maliciously recovered, the data loss is difficult to crack, and the problems of safety and capacity limitation can be well solved.

Description

technical field [0001] The invention relates to the field of data storage security, in particular to a large-capacity data storage device and a data destruction method thereof. Background technique [0002] In a society with rapid information development, data storage devices such as U disks and mobile hard disks have been born. These data storage devices can be connected to external devices such as computers and tablets through specific interfaces, and users can download important data from external devices to data storage devices. For storage, backup or transfer, but the data in these data storage devices is easy to be stolen and copied by others, thus causing losses to users. [0003] The traditional way to prevent data from being stolen in the data storage device is to read the data in the data storage device through specific resource manager software, but this method needs to match specific software on the computer side, so it is not suitable for ordinary users. At pre...

[0003] The traditional way to prevent data from being stolen in the data storage device is to read the data in the data storage device through specific resource manager software, but this method needs to match specific software on the computer side, so it is not suitable for ordinary users

At present, the commonly used method is to destroy the data after use. Most users manually format the large-capacity data storage device and destroy the data in it. However, if the operation is improper during the destruction process, it will If the data is not completely formatted, there is a risk of a third party stealing and maliciously cracking it, resulting in unnecessary losses
