Disclosed is a system and methods for secure distribution of digital content (see the figure). The content is digitized and encrypted forming a secure content container (250). The decryption key (710) and means to authorize the presentation or playing of the material are provided to form a secure player system (750). The content will be limited by a series of negotiated restraints including number of presentations, time of presentation and geographic and/or type of audience limitations. A specific player or projector (600) is physically enabled by the secure player system and ensures that the limitations are met. The system sends a message to the provider upon unauthorized access to the content. The system may deactivate and/or destroy a local copy of the material upon misuse. |
