Error detection of data leakage in a data processing system

Abstract:

A system for detecting data leakage is disclosed. The system intercepts web traffic data, de-duplicates the web traffic data, and extracts data elements from the web traffic data. The system further groups the data elements into multiple clusters based on data types associated with the data elements. The system then identifies data elements in a cluster that were previously sent to a user and identifies allowed data elements from an allow table that are supposed to be sent to the user. The system determines whether there is a data leakage by determining whether the identified data elements in the cluster comprises at least one data element that is not in the identified allowed data elements in the allow table.
