USB flash disk data destruction system, method and device

Abstract

The invention discloses a USB flash disk data destruction system. According to the technical scheme, the USB flash disk data destruction system is characterized by comprising a power supply unit, a disconnection unit, a temperature detection unit and a timing unit; the power supply unit is used for outputting reverse voltage to a USB flash disk, the temperature detection unit is used for monitoring the temperature condition of the USB flash disk in real time and setting a first temperature threshold value, and the timing unit is coupled with the temperature detection unit; the timing unit is used for carrying out timing operation when the temperature of the USB flash disk reaches a first temperature threshold value and is provided with a first time threshold value, and the disconnection unit is coupled with the timing unit and the power supply unit and used for disconnecting the connection state of the power supply unit and the USB flash disk when the time reaches the first time threshold value.The invention aims to provide a USB flash disk data destruction system. The USB flash disk data destruction device can quickly and conveniently perform destruction operation on the USB flashdisk and strictly prevent data from being leaked.

Description

technical field [0001] The invention relates to a destruction system, more specifically, it relates to a U disk data destruction system. Background technique [0002] U disk is the abbreviation of USB (universal serial bus) disk, also known as "U disk" according to the homonym. U disk is a kind of flash memory, so it is sometimes called flash disk. The biggest difference between U disk and hard disk is that it does not need a physical drive, plug and play, and its storage capacity is much larger than that of a floppy disk, which is very easy to carry. When the U disk is discarded, there are the following possibilities: 1. U disk built-in The chip is intact, but the casing is seriously damaged, so throw it away; 2. The built-in chip of the U disk is slightly damaged, and it cannot be connected to the computer normally, so throw it away. [0003] Then when some people get these discarded USB flash drives, after data recovery and certain simple repairs, they can be opened and...

The biggest difference between U disk and hard disk is that it does not need a physical drive, plug and play, and its storage capacity is much larger than that of a floppy disk, which is very easy to carry. When the U disk is discarded, there are the following possibilities: 1. U disk built-in The chip is intact, but the casing is seriously damaged, so throw it away; 2. The built-in chip of the U disk is slightly damaged, and it cannot be connected to the computer normally, so throw it away

[0003] Then when some people get these discarded USB flash drives, after data recovery and certain simple repairs, they can be opened and the information stored in the USB flash drive can be seen. If the stored information includes some personal privacy , once it is restored and made public to the Internet, it will bring distress caused by privacy exposure and some losses caused by data exposure
