A encryption U disk system with journal and audits

Abstract

This invention relates to a code U disc system with log check in computer information safety field, which comprises the following parts: user layer and drive layer set in host end; memory, safety control module and USB interface control module, wherein, the user layer is to provide interacting interface user operation to monitor user operation to generate log information and files read data and drive layer for interacting; one u disc for data coding and check.

Description

technical field [0001] The invention belongs to the field of computer information security, and in particular relates to the design of an encrypted U disk system capable of ensuring the safety of important data stored on the U disk and performing real-time and accurate log records on data operations performed by users. Background technique [0002] With the development of computer technology, computer storage media has gradually replaced paper as the main way of information storage. Paperless office has gradually become the main working method of the government, enterprises and military. However, in the current construction of various network systems, we often only care about the security of data transmitted on the network and the security of identity during access, while ignoring the security of information storage, especially the security of mobile storage media. This has become a new and urgent problem in the field of information security. [0003] The research on the s...

Problems solved by technology

[0005] Through the analysis of the new security requirements, the existing solutions cannot solve the problem of U disk usage auditing well, that is, it is impossible to know what operations the user has performed on the disk, and who has operated the U disk

Also because only using a password lock, the confidentiality of data is difficult to be reliably guaranteed
