Embodiment Construction

[0017] An authentication and control method for audio-visual multimedia information developed by the present invention enables an audio-visual program provider to convert an original file of audio-visual multimedia information, that is, an audio-visual file, into an encrypted audio-visual file through an encryption process , and provide it to consumers through the local area network, the Internet or other methods. When the consumer obtains the encrypted audio-visual file and wants to use the computer to enjoy its content (such as: video or song), this method will make the encrypted audio-visual file The computer actively connects to a server set up by the audio-visual program provider through the Internet, activates an authentication mechanism set up on the server, and reads a certificate provided by the consumer using the computer on the server. After the identity information is correct, it will be verified, and after the verification is correct, a decryption key will be sent ...

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. Background technique [0002] By the way, in recent years, with the gradual popularization of the Internet, consumers can obtain all kinds of information online, which has become a trend of information circulation in the future. The Internet circulates everywhere and quickly becomes the most popular commodity online, which also makes the counterfeiting of audio-visual digital products rampant everywhere in the infinite network world. Therefore, how to use audio-visual encryption technology on online audio-visual digital products, Effectively prevent illegal counterfeiting to protect the intellectual property rights of these audio-visual digital products, and further implement the concept of consumer payment, and make the online consumption mechanism more perfect when welcoming the coming multime...
