| Summary: | The usage of digital video is rapidly increasing recently. The analog CCTV systems are replaced by digital systems. Moreover, digital cameras and smartphones are increasingly popular and becoming affordable. The criminals use these digital devices; particularly smartphones to record crimes such as child pornography and other violent activities. Many at times, these videos are altered or deleted by the criminals in order to avoid persecution by the law enforcement. In digital forensic, carvings of deleted, damaged video files have an important role in searching for evidence. Therefore, many existing tools and techniques such as Scalpel’s, PhotoRec, Bi-Fragment Gap Carving (BGC), Smart Carving and Frame Based Carving attempt to carve the videos files, but some of the carved videos files are usually corrupted or damaged and not playable. However, there is still room for improvement in repair corrupted MP4 videos to make it playable. In this research, MP4-Karver tool is proposed to carve and repair the corrupted MP4 videos. MP4-Karver is developed by using visual studio platform in C# programming language. The proposed MP4-Karver tool focuses on carving, repair corrupted MP4 videos and getting a higher successful rate of playable MP4 video file format. The experimental result shows that the proposed MP4-Karver tool increases the restoration carving and repairing of MP4 corrupted videos with average of 97% improvement as compared to PhotoRec and Scalpel. The MP4-Karver tool is a good alternative for MP4 videos restoration and repairing damaged videos as compared to other tools and techniques. |
