Abstract Digital images are easy to manipulate and edit due to availability of powerful image processing and editing software like picasa, Photoshop. Nowadays, it is possible to add or remove important part from an image without leaving any obvious traces of tampering. Verifying digital images and validating their contents, and identifying forgeries is one of the critical challenges for governmental and nongovernmental organizations and departments. The image integrity verification as well as identifying the areas of tampering on images without need of any expert support or manual process or prior knowledge of original image contents is now days becoming the challenging research problem. The method as in [16] deals with authenticity of images and is based on concept of using illumination color estimation. Recently a new method is also reported for efficient forgery detection particularly for faces in images , that estimates illuminant color using the physics based method as well as statistical edge method which make the use of inverse intensity-chromaticity color space. The estimate of illuminant color is extracted independently from the different mini regions. The method employs SVM for classification. The technique is capable of handling images containing two or more people and needs no expert interaction for detection of tampering. Keywords: Digital Image, Image modification/Forgery, Color constancy, Forgery detection, Illuminant color, skin detection
