This paper presents an optimized watermarking scheme based on the discrete wavelet
transform (DWT) and singular value decomposition (SVD). The singular values of a binary …

The drawbacks of SVD-based image watermarking are false positive, robust and
transparency. The former can be overcome by embedding the principal components of the …

In this paper we aim to present a survey of different techniques on digital image
watermarking. Digital watermarking technique is becoming more important in this …

Speaker identification is a widely used technique in several security systems. In remote
access systems, speaker utterances are recoded and communicated through a …

In this paper, a new SVD-based digital watermarking scheme for ownership protection is
proposed. The proposed algorithm solves the problem of false-positive detection. In …

Digital watermarking is an application associated with copyright protection. Any digital object
can be used as a carrier to carry information. If the information is related to object then it is …

To compromise between imperceptibility and robustness property of robust image
watermarking technique, a RDWT-DCT based blind image watermarking scheme using …

Issues such as content identification, document and image security, audience measurement,
ownership and copyright among others can be settled by the use of digital watermarking …

Digital watermarking techniques have been developed to protect the copyright of digital
media. This paper aims to provide a detailed review and background about the …

In this paper, a new homomorphic image watermarking method implementing the Singular
Value Decomposition (SVD) algorithm is presented. The idea of the proposed method is …
