PEEP- Privacy Enforcement in Email Project.

Breaching information privacy is a critical problem where legal remedies intervene only after the fact rather than prevent it. This paper presents an organizational privacy compliance engine that monitors outgoing emails to detect breaches of a privacy policy in an organization. The PEEP system employs email content analysis techniques to extract information and their ownership. Access to the extracted information is verified by privacy rules assisted by an ontology-based model to represent information disclosure privileges. This paper addresses the issues of, first, the information extraction techniques from email, and second, the implementation of an ontology-based model of multilevel disclosure privileges to represent privacy rules. We experiment with the PEEP system on real life emails in an academic environment to detect breaches of privacy in emails. Our results report an F-score of 71.7% of privacy violations detection.
