Abstract: Computer forensic is a branch of science that does analysis of events happened in digital environment. Every change is traceable in digital form just like physical & chemical form of a material. Now technologies are rapidly growing to make convenient for everybody life. As we know science develops killing materials for us. This only provides some means like data processing, data storing, querying etc to solve our daily hard problems. Once events happened in digital environment will leave the trace or not? If answer is no then what we are developing really become a killing materials nothing more than that. But it is not always true. Every change leaves a trace. These trace should be measured to identify and quantification of changes in digital environment. Today text, image, audio, video and animation various type of data are becoming common to share in digital communication. We all are very use to share our own pictures, videos online with our friends. But if something were changed by any person intentionally or unintentionally then it creates problems for us. In this paper we will discuss important digital documents that can be forged, available forging methods, tracing forgery in digital documents [8], [10], impacts on overall evidences and justice. Our main objective to discus some points in this paper that can be treated as milestones to seize & restore evidences to provide secondary opinion for honorable judiciary.
