A method for preventing the illegal copying of a copy protected content by a computerized system by installing a driver in the operating system of the computerized system for intercepting any attempt of the I/O routines of the operating system to access the device drivers of the Operating System, producing a CRC codes for data read from devices containing original copies, producing a CRC codes for data to be written to devices, and preventing any attempt to write such data whenever the CRC code produced match a CRC code produced for read data. The protection of content stored on a recordable CD can be achieved by recording on the CD a first sA method for preventing the illegal copying of a copy protected content by a computerized system by installing a driver in the operating system of the computerized system for intercepting any attempt of the I/O routines of the operating system to access the device drivers of the Operating System, producing a CRC codes for data read from devices containing original copies, producing a CRC codes for data to be written to devices, and preventing any attempt to write such data whenever the CRC code produced match a CRC code produced for read data. The protection of content stored on a recordable CD can be achieved by recording on the CD a first session including one or more Tracks, each of which includes unique and/or nonstandard data structures. The protected content is then recorded on the CD in a concealed form together with an authentication module capable of determining the existence or non-existence of the unique and/or nonstandard data structures and capable of accessing the concealed content and reveal its content. Whenever attempting to access the CD, the authentication module is activated, and if the unique and/or nonstandard data structures are found on the CD, the concealed content is revealed and accessed. |
