Undeletion is a feature for restoring computer files which have been removed from a file system by file deletion. Deleted data can be recovered on many file systems, but not all file systems provide an undeletion feature. Recovering data without an undeletion facility is usually called data recovery, rather than undeletion. Although undeletion can help prevent users from accidentally losing data, it can also pose a computer security risk, since users may not be aware that deleted files remain accessible.

File carving

All filesystems contain some metadata that describes the actual file system. At a minimum, this includes the hierarchy of folders and files, with names for each. The filesystem will also record the physical locations on the storage device where each file is stored. As explained below, a file might be scattered in fragments at different physical addresses. File carving is the process of trying to recover files without this metadata. This is done by analyzing the raw data and identifying what it is. This can be done in different ways, but the simplest is to look for the signature or "magic n ...

Optimistic decompression

Optimistic decompression is a digital forensics technique in which each byte of an input buffer is examined for the possibility of compressed data. If data is found that might be compressed, a decompression algorithm is invoked to perform a trial decompression. If the decompressor does not produce an error, the decompressed data is processed. The decompressor is thus called optimistically ---that is, with the hope that it might be successful. Optimistic decompression is used as a tool to validate JPEGs that are produced by file carving. The approach can also be used for fragment reassembly ...
