This invention presents a digital licensing scheme that separates the license from the digital file containing the copyrightable material. The files can be downloaded from any server and transferred from user to user, even after the file has been licensed. The invention utilizes producer software running on a vendor's computer, server software from the license provider, and player software on the user's computer. Digitally encrypted communication streams ensure confidentiality between these components. The software checks that the appropriate product license has been purchased by comparing product IDs and user IDs, as well as verifying the operating system ID.
Another notable patent is the "Licensed digital material distribution system and method." This system distributes licenses for copyrighted material separately from the material itself. A producer registers the material with a License Provider, who returns an encryption code for the producer to attach to the digital materials. The vendor then distributes the material to users who purchase a license, which includes an encryption key to decrypt the file. This system incorporates security measures to prevent unlicensed use and distribution.
