Embodiment Construction

[0034] FIG. 1 shows an embodiment of an information control system employing an information access control method according to the present invention. It shows the structure of an information management system that can prevent illegal copying or leakage of information data recorded in a fixed memory device 10 such as a hard disk device (HDD) within the computer system 1 (ie, protect data on the information system).

[0035] In FIG. 1 , a storage device 2 is connected to a computer system 1 . The storage device 2 is compatible with the physical specification of the portable external recording medium 20 , and controls the recording and reading of data from the external recording medium 20 .

[0036] It should be noted that the storage device 2 may be physically separate from the computer system 1 and be connected thereto as an add-on component via a cable or wireless interface, or installed in the computer system 1 as an embedded component so that both can be controlled without e...

Abstract

An information access control method for limiting access to particular information of an information system side according to authentication of an external recording medium. The information access control method accesses the information data on the information system by using an external recording medium. The external recording medium contains system user information and the information system contains corresponding system user information. When the information system user information is sent to the information system as a request for connection to the external recording medium, the information system compares the system user information sent by the connection request and the system user information registered. If the comparison results in coincidence, the external recording medium is allowed to access the information data on the system within a range specified by the system user information.

Description

technical field [0001] The present invention relates to an information access control method for preventing information on a computer system from being leaked, and more particularly, to an information access control system for controlling access to data on a computer system and preventing any data from being leaked to an external recording medium and programs, as well as related external recording media to be used for this purpose. Background technique [0002] Due to the increased popularity of computers in the workplace in recent years, an increasing amount of information is stored on computers every day. Therefore, leakage or theft of company internal information has become an important problem. [0003] There are also incidents in which internal information of a company is illegally copied by an internal person of a company or a person of an external company using an external recording medium such as an optical disc, or is used improperly. [0004] A typical example of...
