We are currently on a verge of a revolution in digital photography. Developments in
computational imaging and adoption of artificial intelligence have spawned new editing …

In this paper, a fragile watermarking scheme for color-image authentication and self-
recovery is proposed. Original image is divided into non-overlapping blocks, and for each i …

This paper presents a Discrete Cosine Transformation (DCT) based effective self-
recoverable fragile watermarking scheme. For each 2× 2 non-overlapping block, two …

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

In this paper, we propose a new self-embedding watermarking scheme with hierarchical
recovery capability. The binary bits in the adopted MSB layers are scrambled and …

Photographs play a very crucial role in our lives, be it in the field of forensic investigation,
military intelligence, scientific research, and publications. Nowadays, most of these …

Abstract Social Internet of Things (SIoT) is one of the emerging research areas which
integrates the Internet of Things (IoT) with social networking concepts. It envisages better …

In this paper, we propose a self-embedding fragile watermarking scheme using vector
quantization (VQ) and index sharing. First, the principle contents of original image are …

This work presents a secure and robust color image watermarking for copyright protection
applications, that is based on exploiting the multi-spectral properties of the primary color …

Authentication and tampering detection of the digital signals is one of the main applications
of the digital watermarking. Recently, watermarking algorithms for digital images are …
