A storage device capable of remotely deleting data and its use method

Abstract

The invention relates to a memory device capable of remotely deleting data and a use method thereof. The memory device is characterized in that the memory device comprises a control unit and an execution unit, wherein the control unit is a preset mobile phone which is communicated with the execution unit; the execution unit receives an instruction sent from the control unit and comprises a double-serial-port single chip microcomputer, a GSM (Global System for Mobile Communications) module, a GPS (Global Positioning System) module, a USB (Universal Serial Bus) reading and writing module, memory equipment, an EEPROM (Electrically Erasable Programmable Read-Only Memory), a lithium battery, a coded lock and a triple gate circuit, wherein the double-serial-port single chip microcomputer serves as a central processing chip to communicate with the GSM module through a first serial port; the double-serial-port single chip microcomputer is connected with the GPS module through a second serial port; the double-serial-port single chip microcomputer is connected with one end of the USB reading and writing module through a parallel port; the other end of the USB reading and writing module is connected with the memory equipment; the double-serial-port single chip microcomputer is connected with the EEPROM through an I2C (Inter-Integrated Circuit) bus; the double-serial-port single chip microcomputer is connected with the lithium battery through A / D conversion; and the lithium battery supplies power to the whole execution unit.

Problems solved by technology

[0002] With the development of science and technology, mobile storage devices, especially USB storage devices, have become the main tool for people to store information because of their small size, large storage capacity, and portability. Every moment there will be problems with storage device loss

[0003] Although there are many methods to ensure the security of storage devices, such as cryptographic technology for software encryption of storage devices; or the use of environmental awareness technology to make storage devices run or destroy in specific environments; Peng Dong et al. Technology Research and Implementation" combines encryption technology and access control technology to prevent the leakage of U disk information, but it cannot retrieve the U disk

This kind of method has certain limitations, if there is encryption, there will be decryption, and the encryption method alone cannot guarantee the security of the storage device; however, the environment awareness technology is limited by the location, and the storage device can only be used in a specific location, making The use of storage devices has significant limitations
