METHOD FOR TRANSFER OF ACCESS CRITERIA FOR MULTI-DOMAIN AND TRANS-DOMAIN DISTRIBUTION OF VIDEO AND OTHER MEDIA CONTENT

摘要

A method is presented where criteria for obtaining access to video or other media content are embedded into the content itself before the content is encrypted and sent or retrieved by a user terminal. The user terminals comprise a security module that decrypts the content and retrieves a copy of the embedded access criteria. The access criteria from the content are compared with rights and privilege information contained in the security module. If match is found concluding that access shall be granted, then the content is released for consumption. Several access criteria may be embedded in the content for it to be rendered on a wide variety of user terminals. A further aspect of the method is simplified secure transfer of the content from the security domain of one type of user terminals or - server to another.
