  • Method and apparatus to inhibit illicit copying from a record carrier to a computer-readable data storage device
    Patent number: 7065506
    Abstract: A technique to prevent illicit copying of a copy-protected CD-ROM into a computer-readable storage drive is presented. In accordance with the present invention, when an authentic copy-protected CD-ROM is inserted into a CD drive and the content of the copy-protected CD-ROM is installed onto a hard disk drive that is linked to the CD drive, the Central Processor Unit (CPU) executes the installer instructions residing in the CD-ROM to create a license file in the hard disk drive. For security reasons, the content of the CD-ROM (e.g., the executable file of the application) is encrypted. When the content of the CD-ROM is copied into the hard disk drive, it remains encrypted. The license file essentially acts as a timer to monitor a predetermined time interval that has been programmed into the license file.

  • Digital record carrier and method for use of same to inhibit copying using decryption code or key from remote depository
    Publication number: 20050246284
    Abstract: A technique to prevent illicit copying of a copy-protected CD or DVD into a computer-readable storage device such as a hard disk drive. When an authentic copy-protected CD or DVD is inserted into a CD or DVD drive and the content of the copy-protected CD or DVD is installed onto a hard disk drive that is linked to the CD/DVD drive, the central processing unit (CPU) associated with the CE/DVD drive and the hard disk drive executes installer instructions residing on the CD/DVD to create a license file in the hard disk drive. For security reasons, the contents of the CD/DVD (e.g. the executable file of the application program, for instance) is encrypted. When the content of the CD/DVD is copied onto the hard disk drive, it remains encrypted. The license file initially acts as a timer in order to monitor a predetermined time interval whether it has been programmed into the license file.
