The invention relates to the multimedia data communication technology field and provides a multimedia data safety monitoring device, a receiving terminal, a multimedia data authentication method and a system thereof. The authentication system comprises: a multimedia data safety monitoring device and a multimedia data receiving terminal, wherein the multimedia data safety monitoring device is used to acquire multimedia data, carry out safety authentication to the multimedia data and stores authentication result information in a safety checking code database; the multimedia data receiving terminal is used to receive the multimedia data, using a same method which the multimedia data safety monitoring device used to carry out the safety authentication to the multimedia data and feed back the safety authentication result information to the multimedia data safety monitoring device. The multimedia data safety monitoring device carries out comparison authentication to the received safety authentication result information and the corresponding safety authentication result information stored in the safety checking code database. If the two are matched, the authentication is passed and the multimedia data receiving terminal decodes and plays. A technical scheme is easy to be realized. Contents are safe and a definition is simple and strictness. Security is high. Implementation and management costs are low.
Description
technical field [0001] The invention relates to the technical field of multimedia data communication, in particular to a multimedia data security monitoring device, a receiving terminal, and a multimedia data authentication method and system. Background technique [0002] With the development of network technology, there are more and more multimedia data content services, and different operators provide users with a variety of multimedia data content through various means. Taking digital TV as an example, operators can transmit massive multimedia data content to digital TV users through broadband IP network or HFC cable network, so that TV users can watch various news, information and entertainment services. However, with the continuous increase of operators and the multimedia data content they can provide, it is urgent to provide a mechanism to ensure the legality of multimedia content, so as to ensure that operators can provide safe content services for end users, and elim...
