Digital watermarking plays vital role to preserve content of digital color image authentication.
This paper proposed semi-fragile watermarking technique using feature extraction. The …

This study has suggested a semi fragile watermarking technique for proving the authenticity
of image. The suggested technique is also used for detecting any tampering may be done …

This paper presents a novel content-based image authentication framework which embeds
the semi-fragile image features into the host image based on wavelet transform. In particular …

An image watermarking is the process of authenticating a digital image by embedding a
watermark into it and protecting the image from copyright violation. This paper proposes a …

The rapid global development of E-commerce in terms of digitalization and distribution of
digital contents in the form of image, audio, video, increases the possibility of unrestricted …

Digital watermarking is a process of embedding watermark signal with its host image to
prove its authenticity. In this paper, Embedding and extraction process are applied on the …

In this paper, we propose a block SVD-based fragile watermarking technique for image
authentication. Using this technique, we can detect any modification made to the image and …

Many digital-image watermarking schemes have been proposed over the last decade, but
most of them have focused on robust, fragile or semi-fragile watermarking. This paper …
