Digital videos are now low-cost, easy to capture and easy to share on social media due to
the common feature of video recording in smart phones and digital devices. However, with …

Online digital content service becomes more and more easily, however, free consumption
and excessive spreading without rights protection will hurt the content providers' benefits …

In this paper, we propose a new fragile watermarking scheme with high-quality recovery
capability based on overlapping embedding strategy. The block-wise mechanism for …

In the current times the level of video forgery has increased on the internet with the increase
in the role of malware that has made it possible for any user to upload, download and share …

In teleradiology, image contents may be altered due to noisy communication channels and
hacker manipulation. Medical image data is very sensitive and can not tolerate any illegal …

Recently, due to the increase in popularity of the Internet, the problem of digital data security
over the Internet is increasing at a phenomenal rate. Watermarking is used for various …

In this paper, we present a passive approach for effective detection and localization of
region-level forgery from video sequences possibly with camera motion. As most digital …

In this paper, we propose a novel self-embedding fragile image watermarking scheme for
tampering recovery based on reference-data interleaving mechanism and adaptive …

Self-embedding fragile watermarking algorithms can perform detection of the manipulated
areas as well as recovery of these detected areas. Most of the self-embedding fragile …

In this paper, a new chaos based watermarking scheme for effective tamper detection in
images is proposed. The proposed scheme is able to detect any possible forgery and spot …
