In the last two decades, the science of covertly concealing and communicating data has
acquired tremendous significance due to the technological advancement in communication …

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 …

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

Due to rapid development of Internet and computer technology, image authentication and
restoration are very essential, especially when it is utilized in forensic science, medical …

Due to the significant growth of video data over the Internet, video steganography has
become a popular choice. The effectiveness of any steganographic algorithm depends on …

Self-embedding watermarking can be used for image tampering recovery. In this work, the
authors proposed a new image self-embedding scheme based on optimal iterative block …

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 …

This paper presents a survey of fragile watermarking schemes for image authentication
proposed in the past decade. The limited embedding capacity and extent of tampering are …

In recent years, a large number of deep neural networks (DNN) models have been built and
deployed, which need to be protected against malicious tampering by the adversary. This …

The aim of designing self-embedding fragile watermarking is copy-right protection, tamper
localization and image recovery. This paper proposes a self-embedding fragile …
