ABSTRACT:
A method and system for distributing digital information is disclosed. Preferably, a user acquires a tangible object which contain a code authorizing access to the digital information. The user reads the tangible object through a reader, which sends the code to a server on which the digital information is stored. The server then authorizes access to the digital information to one or more access devices listed in registries belonging to the user. The user may use the digital information on the terms he agrees to, and, while in use by the user, access to the digital information to other users or other playback devices is disabled. Once the user no longer is using the digital information, the access device erases the digital information, and signals the server that the digital information is no longer in use, thereby re-enabling access to the digital information by the other playback devices listed in the registry.
