ABSTRACT:
The problem to be solved is that once copyright claimed AV data is passed to application software, the application software can freely process the AV data for recording, etc., defeating the purpose of copyright protection. The invention provides a computer which comprises a system section12and an application software section13, and which takes in copyright claimed, encrypted data via a digital interface1for processing therein, wherein the system section12judges that the application software section13is legitimate application software for the protection of copyright, and if the application software is a legitimate one, the system section12passes a key for the encrypted data to the application software section13.
