Abstract: A two-stage, very fast symbol string matching mechanism measures the similarity of content between data sources, allowing for efficient detection and evaluation of exact as well as inexact matches. The disclosed approach pairs complementary encoding technique comprising a first fast lookup that identifies regions of possible similarity, and a second, more computationally intensive analysis that evaluates metrics of similarity and delimits copy boundaries. The original content remains private (encrypted) during processing.
