A Review on Digital Watermarking-Based Image Forensic Technique

Abstract

Due to the advancement of the internet and image correcting software, the problem of integrity and authenticity of the image has become crucial. Forensics of digital image plays a crucial part in verifying the integrity and authenticity of computerized images. Digital watermarking is one of the computationally efficient techniques to verify the digital image’s integrity and authenticity. In this work, an overview of various image forensic techniques is briefly discussed, and an overview of digital watermarking techniques is presented as well. Further, various issues and challenges of digital watermarking and image forensics techniques based on the digital signature are also discussed. The overall aim of this work is to provide researchers with a comprehensive view of different aspects of image forensics based on digital watermarking. This survey will enable researchers to apply efficacious watermarking techniques to verify the authenticity and integrity of digital images.
