在当前的多媒体消息(彩信)运营模式下,存在对内容提供商的版权权益保护不够和对内容缺乏监控的双重问题。在提出的解决方案中,移动网络运营商在彩信的内容或冗余格式中嵌入隐蔽的防伪水印或认证码标记,通过在彩信的下发和转发中识别并统计这些标记实现对版权和内容的监管。分析和实验表明,该方案具有对现有设施改造较小、效率高和识别准确的优点。
In the current operation of multimedia messaging service, there exist the twin problems of limited copyrights protection for content providers and lack of content monitoring. In the solution proposed by this paper, an operator of mobile network is required to embed the hidden label, including the fabrication-proof watermarks or authentication codes, into the multimedia messages or their redundant formats. And by recognizing the labels in the delivery and forwarding of the messages, the operator is able to manage the copyrights and monitor the content. The analysis and experiments show that the scheme has the advantages of less modification of the existing equipment, high efficiency, and good recognition accuracy.
