Abstract

Camera images are amenable for manipulations by varied manageability's and manovorabilities for desperate purposes in the crime scenario. The invention of advanced and modern techniques of reproduction such as photocopiers, scanners have led to the prolifera- tion of original images available in original documents in one form or the other and consequently morphed images are entering in to the court rooms as evidences. Such instances are alarmingly increasing as the functionalities of image editing soft-wares allow an amateur to easily manipulate images. In some cases, they may be in the threshold of the requirements of a legal duplicate. In this paper, a case study of unearthing of such an entry of morphed images into court room in an attempt to derail justice is discussed. A technical approach evolved to detect digital alteration using image processing software Adobe Photoshop. The finding reveals that inconsistencies among the original and scanned images and their infringements have caused distortion. Experimental results demonstrate that scanned images are morphed . Keywords- scanner, signature, image analysis, adobe Photoshop.
