Such inputs have sequences of identical bytes in the same order, although bytes in between these sequences may be different in both content and length.<br><br>CTPH was originally based on the work of Dr. Andrew Tridgell and a spam email detector called SpamSum. This method was adapted by Jesse Kornblum and published at the DFRWS conference in 2006 in a paper 'Identifying Almost Identical Files Using Context Triggered Piecewise Hashing'.";
