DATA LOSS PREVENTION SYSTEM

摘要

A system that detects the possible transmission of information of interest. The system receives a document being transmitted and generates a set of trigrams for the text of the document. The set of trigrams for the document is then compared to sets of trigrams for documents of interest. If the number of matching trigrams between the text of the received document and one of the documents of interest is above a certain threshold value, a possible match is found and indicated by the system.
