Abstract: Modern digital technology and the availability of increasingly powerful image processing tools can easily manipulate the digital images without leaving obvious visual traces of having been tampered, so there is an urgent need to identify the authenticity of images. In the fields such as forensics, medical imaging, e-commerce, and industrial photography, authenticity and integrity of digital images is essential. In this research work, a comprehensive study has been undertaken for accessing and analyzing the threat of Digital Image tampering for security. Various methods and research issues involving the tampering detection and image authentication have been discussed and suitable recommendations for security scenario have been presented.
