Abstract—Image forgery detection and its accuracy are addressed in the proposed work. The image authentication process aims
at finding the originality of an image. Due to the advent of many image editing software image tampering has become common.
The Enhanced hashing approach is suggested for image authentication. The concept of Hashing has been used for searching
images from large databases. It can also be applied to image authentication as it produces different results with respect to the
change in image. But the hashing methods used for similarity searches cannot be used for image authentication since they are no
sensitive for small changes. Moreover, we need a system that detects only perceptual changes. A new hashing method, namely,
enhanced robust hashing is proposed for image authentication, which uses global and local properties of an image. This method is
developed for detecting image forgery, including removal, insertion, and replacement of objects, and abnormal color
modification, and for locating the forged area. The local models include position and texture information of object regions in the image. The hash mechanism uses secret keys for encryption and decryption. IP tracing is done to track the suspicious nodes.
