Read-write management and control system for CD-ROM medium

Abstract

The invention discloses a read-write management and control system for a CD-ROM medium, which is capable of resolving the problem of a traditional file transparent encrypting system that CD-ROM medium read-write operation cannot be managed or controlled and that the use of a special driver device makes the hardware cost high and not convenient to carry. The system comprises an application layer structure and a kernel layer structure. The application layer structure comprises a client terminal and a service terminal, wherein the client terminal comprises an identity verifying module, a monitoring and filtering module and a read-write module. The service terminal comprises a registering module and a tracking / auditing module. The kernel layer structure comprises a filtering driver arranged on the CDROM.sys driver, and the filtering driver performs joint filtering to the upper layer application through the direct use of the commands issued in the form of SCSI and the commands issued by the file system so as to realize the read-write management and control of the disc burned contents.

Description

technical field [0001] The invention relates to the field of information security, in particular to a read-write management and control system for CD-ROM disc media. Background technique [0002] The CD-ROM storage medium is often used to store important electronic documents in confidential departments, libraries, and enterprises. Ensuring the security of electronic information in CD-ROM can effectively prevent the leakage of information privacy. [0003] At this stage, the main method for electronic information encryption and access control of storage media is the file transparent encryption and decryption system. The system usually consists of filter drivers, encryption subsystems, key management, auditing and other modules. The filter driver mainly implements the binding of the CDO of the file system control device and the filtering of the I / O request packet IRP, so as to obtain the IRP signal we need to capture and the content to be encrypted. The encryption subsystem...

AI Technical Summary

Problems solved by technology

But an inconvenient factor is that all the content that needs to be encrypted and written to the disc must be operated with a dedicated optical drive

That is, the user unit has to purchase multiple sets of dedicated optical drives for the use of relevant personnel, which causes an increase in hardware costs and inconvenience in carrying
