Authenmtication and control method for video-audio multimedium information

Abstract

The present invention is an authentication and control method for audio-visual multimedia information, which is applied between a server of an audio-visual program provider and at least one computer. Provide at least one encrypted audio-visual file of audio-visual multimedia information and supply it to consumers through the network. The consumer first activates an authentication mechanism set up on the server; and then transmits the identity information entered by the consumer to the server Authentication; if the identity information is correct, the server will return a decryption key to the computer; the computer will use the decryption key to decrypt the encrypted audio-visual files so that they can be restored to unencrypted audio-visual files for Consumers appreciate; the present invention not only enables the supply of audio-visual programs to accurately control the use of multimedia information through the control and management of the decryption key, but also enables online consumers to use the decryption key differently each time The audio-visual files can be enjoyed on any computer, so that the audio-visual multimedia information has excellent portability.

Description

technical field [0001] The invention relates to computer network encryption technology, in particular to an authentication and control method for audio-visual multimedia information.
