|1. (WO2017015956) NATURAL JEWEL AUTHENTICITY IDENTIFICATION METHOD AND SYSTEM BASED ON MICROSCOPIC THREE-DIMENSIONAL IMAGING TECHNIQUE|
|Title:||NATURAL JEWEL AUTHENTICITY IDENTIFICATION METHOD AND SYSTEM BASED ON MICROSCOPIC THREE-DIMENSIONAL IMAGING TECHNIQUE|
A natural jewel authenticity identification method and system based on a microscopic three-dimensional imaging technique. The method comprises: a shipper scans the whole appearance of each jewel by means of three-dimensional microscopic scanning and completely records appearance characteristics of the jewel; a three-dimensional imaging technique is used to generate a three-dimensional entity image of the jewel; a digest algorithm is used to compress three-dimensional entity image information about the jewel into a unique digest code, wherein the three-dimensional entity image and the digest code are published as publishable archive information about the jewel; if a receiver is a dealer, the same method is adopted to generate a digest code of a natural jewel to be identified, and the digest code is compared with the published digest code; and if the receiver is an individual buyer, after the natural jewel is received, the actual object is amplified and compared with the published three-dimensional entity image, and if the comparison is successful, the natural jewel to be identified is authentic.
