Techniques for controlling the use of data stored on a media or integrated circuit sample are provided. A sample identifier is created at the point of sample use. The type of sample could range from storage media, such as a Digital Video Disc, or DVD, on which, for example, data representing a motion picture is recorded, to an integrated circuit in which computer code is stored. The sample identifier is stored at a location that is different from where the data is to be employed, and compared with other sample identifiers. The use of the data is controlled based on the results of the comparison. |
