Original status of smartphone video by analyzing the data volume according to the recording time

Abstract

Many people use cell phones to record videos because they are equipped with cameras and their performance is improving. Therefore, many imaging media are generated through smartphones in line with technological advances [1]. Most people at the scene of an incident use smartphones to photograph and record the situation. These videos are used as legal evidence and provide important clues to the case. However, the debate over whether this collected evidence is completely reliable is growing with the development of editing technology. With editing technology and the commercialization of user-friendly interfaces, anyone can falsify or edit videos.
