This document proposes a system for detecting data leakage when sensitive data is distributed to third-party agents. The system would watermark or embed fake objects in the distributed data to help identify the source if a leak occurs. Specifically, the proposed system would distribute sensitive data from a data distributor to various agents, with the watermarked or fake objects allowing analysis to see if a leak matches an agent's copy if the data is released publicly. The implementation section outlines an approach involving data allocation, creation of fake objects, and analyzing object overlap to identify the likely leaking agent.
