We present a method by which to determine a synchronzation point within a DEFLATEcompressed bit stream (as used in Zip and gzip archives) for which the beginning is unknown or damaged. Decompressing from the synchronization point forward yields a mixed stream of literal bytes and co-indexed unknown bytes. Language modeling in the form of byte trigrams and word unigrams is then applied to the re...
