【摘要】：在数字电影领域,数字水印是嵌入到影片载体中的可鉴别性标记信号,其中包含著作权人身份、节目特征、设备属性等特定信息。通过隐藏在影片载体中的水印标记信息可以实施版权识别、盗版追踪,也可以判断载体是否被篡改。水印信息具有防探知、防篡改特质,其使用不影响影片载体的应用价值。本文对数字水印的原理、标准依据及其在电影版权保护领域的应用进行了研究,对法证标记的嵌入、处理和检出实际应用进行了分析和说明,探讨了制约水印检出能力的因素,提出了优化数字水印检测流程、提升水印检出效率的技术解决方案。同时,本文对近年来影片盗版追踪的总体情况进行了汇总分析,提出了技术改进方向和实施建议。
[Abstract]:In the field of digital film, digital watermarking is an identifiable signal embedded in the film carrier, which contains specific information such as the identity of the copyright owner, program features, device attributes, and so on. The watermark information hidden in the film carrier can be used to identify copyright, track piracy and determine whether the carrier has been tampered with. Watermark information has the characteristics of anti-detection and anti-tampering, and its use does not affect the application value of film carrier. In this paper, the principle of digital watermarking, the standard basis and its application in the field of film copyright protection are studied, the embedding, processing and detecting of forensic mark are analyzed and explained, and the factors that restrict the ability of watermark detection are discussed. A technical solution to optimize the flow of digital watermark detection and improve the efficiency of watermark detection is proposed. At the same time, this paper makes a summary and analysis of the overall situation of piracy tracking in recent years, and puts forward the technical improvement direction and implementation suggestions.
