In this paper, an algorithm for multiple watermarking based on discrete wavelet transforms
(DWT), discrete cosine transform (DCT) and singular value decomposition (SVD) has been …

The usage of images in different fields has increased dramatically, especially in medical
image analysis and social media. Many risks can threaten the integrity and confidentiality of …

This paper proposes a fragile and blind dual watermarking method for tamper detection and
self-recovery. This method generates two image digests from the host image, based on the …

With the increasing prevalent of digital devices and their abuse for digital content creation,
forgeries of digital images and video footage are more rampant than ever. Digital forensics is …

Digital image watermarking is the most widely used recognized approach to protect data
against piracy. This paper proposes a new blind color image watermarking based on the …

A new blind color image watermarking based on Walsh Hadamard Transform (WHT) is
proposed in this paper which uses Triangular Vertex Transform (TVT) along with WHT. This …

In this paper, an algorithm for multiple digital watermarking based on discrete wavelet
transform (DWT), discrete cosine transform (DCT), and singular value decomposition (SVD) …

In this paper, an algorithm for digital watermarking based on discrete wavelet transforms
(DWTs) and singular value decomposition (SVD) has been proposed. In the embedding …

Multimedia security is extremely significant concern for the internet technology because of
the ease of the duplication, distribution and manipulation of the multimedia data. The digital …

Due to the unlawful manipulation and image processing attacks, the copyright protection of
digital image is paid more and more attention. This paper proposes a digital image …
