Data exchange method for mobile storage medium and device thereof

Abstract

The invention provides a data exchange method for a mobile storage medium and a device thereof. The method comprises the following steps of: storing registration information of registered mobile storage devices; checking whether the mobile storage devices accessing the data exchange device is registered or not according to the registration information, and if so, acquiring security level information of the mobile storage devices from the registration information, otherwise, judging the security levels of the mobile storage devices according to a preset rule; receiving an instruction for data exchange between the two mobile storage equipment, comparing the security levels of the two mobile storage devices, and judging whether the instruction for the data exchange is legal or not according to a comparison result; if so, executing the data exchange, otherwise, refusing to execute the data exchange. By the data exchange method for the mobile storage medium, the confidential data of intranets can be subjected to security protection, the safety of the data exchange of the intranets and extranets can be improved, and the opportunity of spreading virus and Trojan horse to intranet computers can be reduced.

Description

technical field [0001] The present invention relates to the technical field of data exchange of mobile storage media, in particular to a data exchange method for mobile storage media and a data exchange device for mobile storage media. Background technique [0002] With the development of information technology, information security protection has become more and more important. Generally, companies that are strict with information confidentiality clearly distinguish between internal networks and external networks to protect confidential information transmitted in internal networks. Generally, the internal network and the external network do not allow direct access, therefore, the data exchange method between the internal network and the external network is particularly important. [0003] At present, the information exchange methods between the internal network and the external network mainly include: [0004] 1. Burn the data to be exchanged into a CD, and then directly c...

Problems solved by technology

The third method realizes the data exchange of inside and outside network more safely than the second method, yet, because described exchange point computer can't distinguish internal network U disk and external network U disk, therefore may pass through described exchange point computer Only the confidential data exchanged between computers on the internal network is allowed to be copied to the USB flash drive on the external network, resulting in data leakage on the internal network
