Abstract: A computer-implemented method and system to enable out of band tracking for digital distribution are disclosed. The method and system include storing an ancillary data block related to a unit of digital data to be distributed, the ancillary data block being stored separately from the unit of digital data to be distributed, obtaining out of band data associated with the unit of digital data to be distributed, injecting into the out of band data information indicative of the ancillary data block to produce modified out of band data, and delivering the unit of digital data to be distributed with the modified out of band data.

Abstract: Some embodiments of the invention provide an improved spectrometer that measures light emissions and/or reflection from a non-solid material that flows through a system of pipes. This spectrometer is designed to fit into a standard pipe system. The material flows past a distal end of the spectrometer that is inserted in the pipe system. The spectrometer has the ability to project light onto the material and collect a resulting light from the material through the distal end as the material flows past this end.

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.

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.
