摘要

The growth of digital media has enabled the development of multimedia manipulation systems. With the accessibility of editing tools, the swift exchange of images online has led to increased image manipulation. This situation underscores the importance of protecting content authenticity and maintaining image integrity through tamper detection systems. Among the various techniques developed to safeguard multimedia data, digital watermarking has garnered attention for its role in content authentication, tamper detection, localization, and recovery. Advancements in photographic technology, including the camera capabilities of Android and iPhone devices, have also made capturing dynamic, highly textured images much easier. As a result, this review article discusses the limitations of different watermarking systems in detail, along with an analysis and comparison of various tampering schemes. We begin by presenting a commonly used dataset, followed by descriptions of various image-processing attacks and explicit performance evaluation metrics. Furthermore, we compare the experimental results of a state-of-the-art system, highlighting the effectiveness of both conventional and advanced watermarking techniques in terms of tamper localization and self-recovery. This review article provides a comprehensive study of existing systems in the fields of tamper detection, localization, and self-recovery. Additionally, it discusses recent developments in watermarking techniques, as well as the challenges and issues that need to be addressed in this area.
