Abstract
A system and method for unorchestrated determination of data sequences using “sticky byte” factoring to determine breakpoints in digital sequences such that common sequences can be identified. Sticky byte factoring provides an efficient method of dividing a data set into pieces that generally yields near optimal commonality. This is effectuated by employing a rolling hashsum and, in an exemplary embodiment disclosed herein, a threshold function to deterministically set divisions in a sequence of data. Both the rolling hash and the threshold function are designed to require minimal computation. This low overhead makes it possible to rapidly partition a data sequence for presentation to a factoring engine or other applications that prefer subsequent synchronization across the data set.
