ABSTRACT
The contents of the digital images can be easily manipulated with image editing software like Adobe Photoshop, Pixelmator, Inkscape, Fireworks, etc. In real life applications, it is indispensable to check the authenticity of the digital images because forged images could deliver misleading information and messages to our community. Different tools have been developed to detect the forged images. In literature, there is no study which presents an insight into image forensic tools and their evaluation on the basis of different criteria. Therefore, to address this issue, we present an insight into digital image forensic tools; and evaluate it on the basis of 15 different parameters like “error level analysis”, “metadata analysis”, “JPEG luminance and chrominance data”, etc. For our experimental work, we choose “FotoForensics” tool to show the forged region in digital images; and JPEGsnoop tool has been used to extract the metadata of the images.
