CONTROLLING DISTRIBUTION OF DIGITAL CONTENT

摘要

A method of controlling distribution of digital content (116) is presented. A version (106) of a program (100) is needed to use the content. A plurality of versions of the program (100) is generated, each version being unique with respect to incorporated code fragments and/or associated locations thereof. The plurality of respective code fragments (118) each cause a processor to perform a respective test regarding a data characteristic on content to be processed by the program for restricting the processing of content for which the permission has not been granted. The respective code fragments (118) are incorporated at respective locations in the program (100) to obtain the version (106) of the program (100).
