Current security systems dealing with sensitive private data do not provide sufficient options to find data leaks. An approach to find the last authorized receiver of a protected copy is proposed in this paper. Existing security concepts are extended by a new security service based on reliable tracking data embedding. Additionally, a new mechanism to protect the new tracking data is shown. Digital watermarking techniques are used to provide tracking abilities for forwarded copies of the protected data. This paper briefly describes approaches to improve security for both the owner of protected data and its recipients.
