Review Analysis of Image Forgery Detection Technique for Digital Images

Navneet Kaur, Navdeep Kanwal


Abstract--Digital visual media have turned into the principle data bearers in the computerized time. Recently the quality of advanced visual data has been questioned because of straightforwardness in duplicating both its source and content. Digital image forensics is a shiny new research field which goes for approving the genuineness of pictures by recouping data about their history. Two fundamental issues tended to are: the recognizable proof of the imaging gadget that caught the image, and the detection of hints of forgeries. In the fields for example crime scene investigation, medical imaging, e-commerce and mechanical image validness and integrity of advanced pictures are the key. Further image forgery can be active or passive. In active approach the digital image requires some kind of pre-processing such as watermark or signatures generated at the time of creating the image. Passive approach includes the concept of copy move forgery, image splicing and retouching which is a great challenge in image processing techniques.


Keywords--Digital image tempering, copy move forgery, image splicing, DCT, SIFT.
