Example Embodiment

[0025] Inspired by the current application of data ferry to physical gatekeepers for data exchange, the present invention combines data ferry with TNC and identity authentication to provide solutions to the hidden security hazards brought by mobile storage devices.

[0026] The internal framework of the mobile storage device used in the method of the present invention is as figure 1 As shown, the smart card chip, data exchange area and private area are built in the mobile storage device after the smart card technology transformation. The data exchange area is used as the transition area between the external environment and the private area. All access operations to the private area will be blocked. The area is used to store encrypted confidential files and other data information, and the unique identification file of the mobile storage device is stored in this private area. The data exchange area communicates with the USB interface through a dedicated channel. The dedicated chann...

Abstract

This invention discloses a mobile storage device, a data safety transmission method and system. The device is internally equipped with an intelligent card chip, a data exchange area and a privacy area after the intelligent card technology change, wherein the data exchange area, the privacy area and a memory in an internal network host terminal are combined with matched software and hardware to realize the pure data safety transmission without protocol, based on which, the user authorization method is added, such that each data transmission operation in accordance with the user thought is realized, thereby effectively preventing the attacks of virus and Trojan. This invention guarantees the credibility of the user identity and the mutual credibility between the internal network host terminal and a mobile storage device via fingerprint authorization and bidirection authorization, realizing that the secret document only can be accessed in the safe environment via the authorized user. Finally, the mutual operation between the mobile storage device and the internal network terminal is recorded in a visit diary via an audit database and a fingerprint database of an authorization server, thereby realizing the traceability of the identity of the mobile storage device holder.

Description

technical field [0001] The invention belongs to the field of information security, and in particular relates to a mobile storage device, a method and a system for securely transmitting confidential information by using data ferries, and the invention ensures the security and confidentiality of information transmission between storage devices. technical background [0002] In recent years, with the acceleration of my country's informatization construction, "e-government" came into being and developed at an unprecedented speed. E-government is reflected in all aspects of social life: industrial and commercial registration declaration, online tax declaration, online customs declaration, fund project declaration and so on. E-government is closely related to the interests of the country and individuals. In the construction of my country's e-government system, the external network is connected to the general public, the internal network is connected to the desktop office system of...
