AI Technical Summary

Problems solved by technology

Without the correct protective case, the data cannot be read and the media cannot be used
This device offers minimal protection in the sense that the authentication program can be suppressed on the computer and then there is no longer any protection
Furthermore, protective boxes are typically associated with a separate media type, resulting in cumbersome and complex security management as a new protective box is required for any new media type

Embodiment Construction

[0022] figure 1 A data storage medium 10 is shown. The medium integrates a portable object 20 and data exchange means. The medium 10 includes three main regions. The peripheral area 11 is capable of storing data. The other two areas are the central area. One area is the hole 13 provided in the center of the medium and in which the mechanical pin can slide, so that said area corresponds to the axis of rotation. Another area is an intermediate area 12 disposed between the hole 13 and the peripheral area 11 and does not include data. The portable object 20 is integrated in the central area of ​​the medium as intermediate area 12 . Such as figure 2 As shown, the portable object 20 includes, for example, a memory 22 and a contact block 23 for establishing electrical contact with a terminal. The memory 22 includes a security key K1. The key K1 is preferably individual for each medium, in other words, it is provided without repetition in the medium it refers to or in other m...

Abstract

The invention concerns a protected optical disk for storing data. It also concerns a method for protecting said disk. The invention is characterized in that said disk firstly comprises a portable object comprising a memory including at least one secret key, and secondly data exchange means, said key making it possible to decrypt the data of said disk whilst remaining in said portable object, said exchange means making it possible to exchange said data between said portable object and said disk. The invention can be applied in particular to CD-ROMs.

Description

technical field [0001] The invention relates to an optical disc for storing data and also to a method for protecting said optical disc. [0002] The invention is particularly suitable for application in data processing, games, audio-visual and other fields. Data storage media, especially optical discs, contain data generally used on computers and television monitors such as text, images, sounds, or software applications. Background technique [0003] Using software, a large number of fraudulent copies of the data contained in the media are made accessible to all users. These software applications are capable of duplicating data on the media despite copyrights protecting said data. One known arrangement in the prior art utilizes a protective box to prevent private copying of data contained in a medium. This cartridge, which includes an electronic identification circuit, is connected, for example, to the computer into which the medium is introduced. ...
