Abstract

The invention discloses a data separate storage and reduction key disk. The key disk comprises a USB control chip, a separation and reduction processing chip and a flash memory chip. The USB control chip receives and analyzes commands and data transmitted by a drive program through a USB port. The flash memory chip receives commands and data sent by the separation and reduction processing chip and stores the data. The separation and reduction processing chip is connected with the USB control chip and the flash memory chip and separates and reduces the data. An electronic document is separated step by step through the chips in the key disk, two data strings are generated finally, the two data strings are stored separately, a user can prevent the electronic document from being divulged just by ensuring the security of any data string, and therefore an effective document divulging prevention means is provided. The means has higher protection intensity than an existing security and secrecy system and is suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a key disk for separate storage and restoration of electronic documents. Background technique [0002] The security protection of electronic documents is one of the core issues of information security. There are a series of software and hardware systems and methods for its security management, but the technical means used mainly include the following methods. [0003] (1) Access control based on identity authentication. Typically, the server centralized storage method is adopted. After the client has the server to authenticate the user identity, the client is granted corresponding permissions, such as reading, writing, copying, and deleting. [0004] ⑵Encrypted storage method. Files are encrypted and stored in storage media such as hard disks, mobile hard disks, and U disks. The security of files is determined by the security of keys and the strength of encryption algorith...
