【摘要】：在數(shù)字電影領(lǐng)域,數(shù)字水印是嵌入到影片載體中的可鑒別性標(biāo)記信號(hào),其中包含著作權(quán)人身份、節(jié)目特征、設(shè)備屬性等特定信息。通過隱藏在影片載體中的水印標(biāo)記信息可以實(shí)施版權(quán)識(shí)別、盜版追蹤,也可以判斷載體是否被篡改。水印信息具有防探知、防篡改特質(zhì),其使用不影響影片載體的應(yīng)用價(jià)值。本文對(duì)數(shù)字水印的原理、標(biāo)準(zhǔn)依據(jù)及其在電影版權(quán)保護(hù)領(lǐng)域的應(yīng)用進(jìn)行了研究,對(duì)法證標(biāo)記的嵌入、處理和檢出實(shí)際應(yīng)用進(jìn)行了分析和說明,探討了制約水印檢出能力的因素,提出了優(yōu)化數(shù)字水印檢測流程、提升水印檢出效率的技術(shù)解決方案。同時(shí),本文對(duì)近年來影片盜版追蹤的總體情況進(jìn)行了匯總分析,提出了技術(shù)改進(jìn)方向和實(shí)施建議。
[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.
