Optimistic decompression : ウィキペディア英語版 | 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.〔(【引用サイトリンク】title=Digital media triage with bulk data analysis and bulk extractor )〕 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 carving by attempting to combine different combinations of fragments, looking for a combination that produces neither decompression errors nor visual discontinuities. ==References==
