Realization of Anti-counterfeiting and Traceability of Ceramics Based on Computer Vision and Blockchain Technology-Taking Jingdezhen Ceramics as an Example

Jingdezhen ceramics have a long history and are world-famous, and thus often become the object of imitation. Aiming at the current ceramic anti-counterfeiting traceability technology is not precise enough, a new treatment program is proposed. Firstly, professional equipment is used to collect the ceramic micropores, due to the randomness and uniqueness of the arrangement of micropores in the ceramic microstructure. afterwards, these micro-holes are processed by Canny edge detection method and then combined with high-precision SIFT method of computer vision for feature extraction. In the next part, this paper introduces the Interplanetary File System (IPFS) combined with decentralized and difficult to tamper with blockchain technology to write a smart contract for traceability. Finally, In the identification process, the picture to be compared with the picture stored on IPFS is compared using knnmatch, and if it meets the principle of 3 times the standard deviation, it is authentic, and vice versa, it is a fake. The experimental results show that the results can be used as a powerful basis for ceramic anti-counterfeiting traceability.
