A Secured Approach for Watermark Embedding using Key based Gödelization Technique under Spatial and Frequency Domains

The huge availability of multimedia data on the internet makes the creation, modification and distribution of the multimedia content easy and affordable. This improvement in the digital techniques has led a path to unauthorized access, copying and distribution of multimedia data, which throws a serious challenge in the field of copyright protection. This paper focuses on providing security and authentication through a method termed Godelization for the purpose of encryption and Location Decision Embedding Technique(LDET) for multimedia data embedding.

Librarians and copyright

AbstractThe contribution presents a collection of basic information from the field of copyrights, which Slovene librarians should be familiar with since their everyday work with materials and contacts with users increasingly touches upon issues of the protection of author’s interests and the public rights of access to information. The paper gives a short historical survey of the development of copyrights abroad and particularly in Slovenia, an overview of acts adopted in Slovenia and international contracts from the field of copyright protection. Special attention is paid to the current articles of the Slovene Copyright Act, particularly those affecting the activities of public libraries.

A novel signature based on the combination of global and local signatures for image copy detection

ABSTRACTTo prevent digital image from unauthorized use, image copy detection is an important technique in the field of copyright protection. The conventional methods of image copy detection concentrate on extracting global or local signatures to resist various kinds of copy attacks. However, the global signatures are sensitive to some geometric transformations, such as rotation and cropping, while the local signatures are not discriminative enough to identify copies from similar images. Considering both the robustness and discriminability, a novel image signature based on the combination of global and local signatures is proposed for image copy detection. Firstly, the interest points are detected from a given image by using the Hessian–Affine detector. Secondly, the image is divided into some circle tracks, and thus the interest points are distributed into these tracks. Finally, to combine the advantages of the circle‐track‐based global signature and the interest points, the global distribution characteristics of interest points based on circle tracks are used to generate our image signature. Experimental results demonstrate the effectiveness of our proposed method in the aspects of both robustness and discriminability. Copyright © 2013 John Wiley & Sons, Ltd.

A Novel Technique for Copyright Protection of Images Using Hybrid Encryption Model

In this paper, we present a robust and novel strategic invisible watermarking scheme which can be used in the field of copyright protection. The novelty of our algorithm lies in the creation of a compound watermark image using the target image and the key image, where both of them are self encrypted. The self encryption concept adds an extra level of data security along with the security supported by the watermarking technique. Again, our method results a single invisible watermarked image which will be sent to the recipient and from that image, both the key and the target image can be extracted with no distortion using only the proposed extraction algorithm. Results of exhaustive experimentation using standard input color images demonstrate the robustness and efficiency of our approach.

A wavelet-based watermarking algorithm for ownership verification of digital images

Access to multimedia data has become much easier due to the rapid growth of the Internet. While this is usually considered an improvement of everyday life, it also makes unauthorized copying and distributing of multimedia data much easier, therefore presenting a challenge in the field of copyright protection. Digital watermarking, which is inserting copyright information into the data, has been proposed to solve the problem. In this paper, we first discuss the features that a practical digital watermarking system for ownership verification requires. Besides perceptual invisibility and robustness, we claim that the private control of the watermark is also very important. Second, we present a novel wavelet-based watermarking algorithm. Experimental results and analysis are then given to demonstrate that the proposed algorithm is effective and can be used in a practical system.

Digital rights management, copyright, and Napster

Digital Rights Management technologies in the field of copyright protection should meet four objectives: • give consumers new freedom to enjoy music and other forms of content; • give copyright owners and other value chain participants the means to manage and protect their rights in published works; • implement elements of law, such as copyright exceptions, that ensure that rights are managed in accordance with the public interest; • provide users with the means to manage their legitimate personal rights and interests.We sketch how these goals can be achieved with current technology for peer-to-peer Digital Rights Management (DRM). This technology can ensure the neutrality, security, commercial reliability, and trusted interoperability of applications and services used to protect and manage rights in all forms of information, including creative works protected by copyright. The rapidly evolving area of digital commerce in information requires a framework of commercial trust comparable in scope, and at least as reliable, as the systems of trust that underpin commerce in the physical world.
