The use of Watermarks in the Protection of Digital
نویسندگان
چکیده
The watermarking of digital images, audio, video and multimedia products in general has been proposed for resolving copyright ownership and verifying originality of content. This paper studies the contribution of watermarking for developing protection schemes. A general watermarking framework (GWF) is studied and the fundamental demands are listed. The watermarking algorithms, namely watermark generation, embedding and detection, are analyzed and necessary conditions for a reliable and eecient protection are stated. Although the GWF satisses the majority of requirements for copyright protection and content veriication, there are unsolved problems inside a pure watermarking framework. Particular solutions, based on product registration and related network services, are suggested to overcome such problems.

متن کاملThe Impact of Digital Government on Whistleblowing and Whistle-blower Protection: Explanatory Study
This paper focuses on the contribution of digital government (DGOV) to Whistleblowing (WB). While considerable efforts have been devoted to DGOV and WB separately, research work at the intersection of these two domains is very scarce; hence and a systematic DGOV for WB (DGOV4WB) research framework has yet to emerge. This paper aims to identify the potential issues in whistleblowing and explore ...
متن کاملA Review of Digital Watermarking
This paper reviews a number of aspects of Digital Watermarking. Watermarking can be applied to many digital documents to protect against copyright infringements, including image, text and video formats. Image watermarking is commonly applied in the spatial and transform domains to achieve robust protection. Watermarking also has a role in legal aspects where the method can be used in a court of...
