Abstract

The invention is applied to the technical field of information security, and provides a watermark generation method, a client side and a server. The method includes the steps of sending logging information to the server so as to enable the server to verify the identity of a user on the client side according to the logging information, generating unique identification data corresponding to the user on the client side, and sending the unique identification data corresponding to the user on the client side to the client side when verification of the identity of the user on the client side passes; receiving the unique identification data sent by the server; generating watermarks according to the unique identification data and superimposing the watermarks to multimedia data to be played. The identity of a publisher of the multimedia data can be verified through the watermarks in the multimedia data, the situation that the multimedia data are obtained to carry out infringement through recording or shooing and other non-contact modes is achieved, and a spreading source can be effectively tracked.

Description

technical field [0001] The invention belongs to the field of multimedia technology, and in particular relates to a watermark generation method, a client and a server. Background technique [0002] With the rapid development of computer network technology and multimedia technology, people obtain various multimedia data through the network, such as video data. While these data bring convenience to people's life, the security protection of various multimedia data has become increasingly prominent , pirates can spread unauthorized multimedia data at low cost, so the protection of multimedia data has become very urgent. At present, the protection method of multimedia data mainly uses watermark technology, for example, video watermark, watermark is loaded in multimedia data Digital watermarking on the Internet, which uses the redundant data and randomness that are common in multimedia data to embed information representing copyright into the original multimedia data, thereby prote...
