dHash-based Anti-Counterfeiting Scheme: Against Tag Re-application Attacks on Batik Tulis

Batik Tulis is a cultural heritage that has historical and economic value. Batik Tulis has its own uniqueness, where Batik Tulis is different from each other even though it has the same motif and is made by the same producer, because Batik Tulis is made manually (handmade) using a tool called "canting". This uniqueness makes Batik Tulis has a fairly high economic value. However, this uniqueness is often exploited by irresponsible parties, by counterfeiting Batik Tulis. In order to address this issue, we developed an anti-counterfeiting scheme that focuses on previously developed tag re-application attacks detection. This approach utilizes of NFC tags, public key cryptography and Perceptual Hash Function (PHF), i.e., difference hash (dHash). dHash provides the relationship between the product and the data stored by the NFC tag. The scheme we have developed is proven to be able to detect tag re- application attack scenarios that the previous scheme could not detect.
