Document Tracking - On the Way to a New Security Service
Rainer Schick, Christoph Ruland · 2011
This paper proposes a new security service that provides reliable technologies for traitor tracing. As current systems do not provide sufficient options to find out who distributed a document in an unauthorized way, an approach for solving this security gap is proposed. Existing security concepts will be extended by a new service based on reliable tracking data embedding. Additionally, a new method to hide the structure of data is introduced. Summarized, the proposed scheme enhances security against attacks from authorized personnel who have got into legal possession of confidential information.
