A Secure and Practical Fingerprinting Protocol for Industry Design Map

Digital fingerprinting is an emerging technology to protect the digital data from illegal redistribution by dishonest customer, where each distributed copy is labeled with unique identification information. Industry design map is one of the most important digital assets for both of the designer and company. However, industry design maps are usually used for unintended purposes by those dishonest customers. Piracy of industry design map becomes increasingly rampant in recent years, since the dishonest customer can easily duplicate, modify and redistribute the received copy. How to effectively protect the costly industry design map from unauthorized using has become increasingly critical, especially considering the ease of manipulating digital industry design map and the open Internet environment. This paper proposed a secure and practical fingerprinting protocol for protecting the copyrighted industry design map. In the proposed scheme, the designer can trace the traitors from a pirated copy by means of the embedded unique fingerprint information, while the customer is immune of being framed due to the asymmetric property.
