Plain Text Zero Knowledge Watermarking Detection Based on Asymmetric Encryption
نویسندگان
چکیده
Digital watermarking technology plays an important role in the areas of copyright protection and identity tracing for owners of digital mediums. At present, the security of the watermarking scheme is facing a great threat. However, the existing Zero knowledge-based watermark detection scheme (ZKWD) are still facing some challenging problems, such as ambiguity attacks. In this paper, a public ZKWD protocol is proposed for plain text, and the homomorphic property of asymmetric encryption algorithm in the multiplication operation is used to prevent the owner from cheating by ambiguity attacks. Compared with existing methods, the security of our proposed ZKWD scheme is improved by using the improved feature extraction algorithm.

Proposing an effective approach for Network security and multimedia documents classically using encryption and watermarking
Local binary pattern (LBP) operators, which measure the local contrast within a pixel's neighborhood, successfully applied to texture analysis, visual inspection, and image retrieval. In this paper, we recommend a semi blind and informed watermarking approach. The watermark has been built from the original image using Weber Law. The approach aims is to present a high robustness and imperceptibi...
متن کاملMultimedia asymmetric watermarking and encryption
An asymmetric watermarking algorithm is presented, involving a private key for embedding and a public key for detection, joint with a suitable encryption scheme, thus achieving a double security level for digital data protection. A commutative scheme is designed based on linear algebra and on a secret random permutation, allowing both to cipher watermarked data and to mark encrypted data withou...
متن کاملA joint asymmetric watermarking and image encryption scheme
Here we introduce a novel watermarking paradigm designed to be both asymmetric, i.e., involving a private key for embedding and a public key for detection, and commutative with a suitable encryption scheme, allowing both to cipher watermarked data and to mark encrypted data without interphering with the detection process. In order to demonstrate the effectiveness of the above principles, we pre...

This paper addresses the problems and threats associated with verification of integrity, proof of authenticity, tamper detection, and copyright protection for digital-text content. Such issues were largely addressed in the literature for images, audio, and video, with only a few papers addressing the challenge of sensitive plain-text media under known constraints. Specifically, with text as the...
