Abstract

Embodiments of the invention provide a method and a system of tracing a source of leaked information owned by an organization after the information has been leaked on an external network. An identity-relationship database is built, wherein the identity-relationship database contains information linking, either directly or indirectly, an employee of the organization to one or more network identities, and to network identities of others with whom the employee communicates. The leaked information on a site on the external network is located, and a network identity of the poster of the leaked information on the external network is determined. It is determined whether one or more links in the identity-relationship database connect the network identity of the poster of the leaked information to the employee. If the one or more links connect the network identity of the poster of the leaked information to the employee, the employee is identified as a possible source of the leaked information.
