In the past two decades, reversible data hiding (RDH), also referred to as lossless or
invertible data hiding, has gradually become a very active research area in the field of data …

Image forensics is an investigation of digital images to identify manipulations that have been
done on them. Nowadays, due to the availability of different low-cost devices for capturing …

Among various digital image formats used in daily life, the Joint Photographic Experts Group
(JPEG) is the most popular. Therefore, reversible data hiding (RDH) in JPEG images is …

It is of great importance in telemedicine to protect authenticity and integrity of medical
images. They are mainly addressed by two technologies, which are region of interest (ROI) …

The joint photographic experts group (JPEG) is the most popular format of digital image. In
this paper, a novel reversible data hiding scheme based on JPEG image is proposed. In …

This paper proposes two novel self-embedding watermarking schemes based upon a
reference sharing mechanism, in which the watermark to be embedded is a reference …

In this paper, we propose a new high-capacity reversible data hiding method for JPEG-
compressed images. This method is based on modifying the quantization table and …

The authenticity and integrity of medical images in telemedicine has to be protected. Robust
reversible watermarking (RRW) algorithms provide copyright protection and the original …

This paper presents a singular-value-based semi-fragile watermarking scheme for image
content authentication. The proposed scheme generates secure watermark by performing a …

In this paper, we propose a novel fragile watermarking scheme with content restoration
capability. Authentication-bits are produced using the image hashing method with a folding …
