A study on the guarantee of authenticity and permanent preservation of digital image evidence

Abstract

Investigators acquire and analyze various forms of evidence at the scene of the incident and identify the substantive truths associated with the incident. In particular, investigators in charge of primary investigations shoot various digital photographs and videos and analyze them to find clues to investigations.With the advancement of science and technology, digital photographs and moving pictures have been generalized in the event scene recording method through sketching or analog photography, and it is now possible to reproduce the scene using a 3D stereoscopic scanner. Records of investigations by the first investigating agency are sent to the prosecutors along with various evidence. Currently, only a few photographs or images necessary for investigation are recorded in the digital image recordings taken by the investigator, and the management system of the remaining data is insufficient.The rapid development of science and technology, and the fact that decades after its occurrence, are being resolved through scientific investigations, if the video recordings taken by investigators are well managed and preserved, it will be an important key to resolving the unsolved incidents. Through this study, it will be helpful to develop the scientific investigation by suggesting the authenticity guarantee system and the systematic preservation and management plan for the digital image evidence taken by the investigator.
