Verification method based on storage medium private space of USB flash memory disc

Abstract

This invention discloses a kind of verification method of the USB flash disk memory medium private space. It has the module that can use the common USB flash disk memory medium private space to verify. The control chip of USB flash disk receives the read / write instruction from verification module, judges whether to execute the read / write operation to the private space. If yes, it executes the read / write operation to the private space; if not, it executes the read / write operation to the normal space. So it can utilize the USB flash disk private space that cannot be seen, be deleted or be copied to store various verification information. And the USB flash disk normal space can store general data. It can realize security, convenient encryption and verification mechanism.

Description

technical field [0001] The invention relates to a verification method based on a USB flash disk, in particular to a verification method based on a private space of a USB flash disk storage medium, and belongs to the field of computer security. Background technique [0002] Existing computers generally do not have encryption devices. In today's society, the privacy of personal computers is getting more and more attention, with special emphasis on the security of business secrets and personal data. The existing computer encryption function is generally realized by software, but the possibility of software being cracked is increasing, and the information on the computer is also becoming more and more insecure. At present, there are methods of using hardware encryption on the market, mainly using Smart Card, fingerprint identification, hardware dongle, but these methods have the following disadvantages: [0003] 1. Lack of universality and narrow coverage, for example, many co...

AI Technical Summary

Problems solved by technology

[0003] 1. Lack of universality and narrow coverage, for example, many computers do not support Smart Card;

[0004] 2. The mechanism and circuit are complicated, resulting in high cost;

[0005] 3. This kind of encryption hardware has a single function, and there is not much advantage for users

[0006] At present, there are also products encrypted by Universal Serial Bus (USB) flash disk, but the encrypted information is placed in the ordinary space, and ordinary users can view, copy and delete, and the security of the encryption is not well guaranteed.
