AN ASSESSMENT OF DIGITAL IMAGE FORGERY DETECTION TECHNIQUES

Dhara Anandparav

With advent of many tools in the digital images, image for gery is the big concern today in Digital Forensics Industry . Digital Image for gery is one of the well-known field in which one can change image in different ways using several powerful editing softwar e's, as a result it become a serious social problem. For this, researchers continuously exploring new approaches to detect image for gery areas and change it to original pixel values if possible. In recent years, the detection of for ged region has become one of the most active research topics in blind image for ensics. Many techniques and algorithms have been proposed to process on post-processed images. This paper surveys these different techniques and its limitations and based on the outcomes it draws the line to exhibit the futur e concern areas in digital image for gery detection.
