Forensic Reconstruction of Fragmented Variable Bitrate MP3 files
File carving is a technique used to recover data from a digital device without the help of file system metadata. The current file carvers use techniques such as using a list of header and footer values and key word searching to retrieve the information specific to a file type. These techniques tend …
