Abstract:
1. A method comprising: associating, by a registry server, for each of a plurality of instances of content, a unique identifier of a given instance of content, an ownership identification for said given instance of content, and an instance of ownership of said given instance of content, in a registry; receiving, by a registry server, a request to access a particular instance of content, wherein said request includes a unique identifier of said particular instance of content and an ownership identification of a user; authenticating, by a registry server, said user in response to receiving said request to access said particular instance of content; determining, by said registry server, an instance of ownership of said particular instance of content from said registry according to said unique identifier of said particular instance of content and said ownership identification of said user, if said user is authenticated; providing, by said registry server, a content key to an access device of said user, wherein said content key includes said unique identifier of said particular instance of content, said ownership identification of said user and an instance of ownership of said particular instance of content, wherein said instance of content and said content key is stored in a location that is local to or remote from said user and wherein said instance of content and said content key is accessible to said user on demand; accessing, by said access device of said user, a decryption key for decrypting said particular instance of content according to said instance of ownership of said particular instance of content if said content key verifies that said user is permitted to access said particular instance of content; and upon ascertaining that said instance of ownership corresponds with full ownership of said instance of content, allowing said user to access said particular instance of content using said decryption key without restriction, wherein said full ownership is transferable to another user with a transfer of said association thereto in said registry.
