LNJN National Institute of Criminology and Forensic Science, Ministry of Home Affairs, Gov't of India
Forensically and JPEGMARK, are open-source image analysis tools, which we have used for detecting the cloned regions in a forged image, downloaded from social media site. This tool is also used to extract embedded and hidden strings of data from the image, in the absence of EXIF metadata (stripped-off by the social media site) to indicate software used to process the image, origin of the image etc. It is extremely useful and powerful tool, which can perform multiple tasks at the same time.About Kumarshankar Raychaudhuri
