[PDF][PDF] Feature based image authentication using symmetric surround saliency mapping in image forensics

C Nandini - International Journal of Computer Applications, 2014 - Citeseer
For an efficient image security, image hashing is one of the solutions for image
authentication. A robust image hashing mechanism must be robust to image processing
operations as well as geometric distortions. A better hashing technique must ensure an
efficient detection of image forgery like insertion, deletion, replacement of objects, malicious
color tampering, and for locating the exact forged areas. This paper describes a novel image
hash function, which is generated by using both global and local features of an image. The …
