An Analysis on Image Forgery Detection Techniques.

In the recent trends and technology we found that the digital image plays an important role. The digital images are widely used in various fields. The validation is now becomes a challenging task because of advancement in the tools and technology. The various tools are used to modify the digital image to create fake digital images. The several research has been carried out in the field of image forgery detection. In this paper attempted to review the existing technique to identify the forgery in an image. Accordingly related papers are reviewed and analyzed. The active and passive are the two approaches in the image forgery detection technique. The digital signature and digital watermarking are the two methods in active approach, and in passive approach various techniques are there such as copy-move, splicing, resampling etc., In this paper we describe the comparative analysis of different types of image forgery detection technique along with future work to be carried out.
