Anti-interference encrypted fan-circular coding and decoding method for commodity outer package

The invention provides an anti-interference encrypted fan-shaped circular coding and decoding method for an outer package of a commodity, and relates to a circulation commodity anti-counterfeiting tracing technology. According to the method, the commodity information is encrypted, and then the fan-shaped circular graph is generated and sprayed on the commodity, so that the information label on the circulating commodity has the characteristics of uniqueness, anti-interference performance, traceability and the like. According to the invention, the traceability and anti-interference performance of commodity circulation can be improved. 本发明提供了一种用于商品外包装的抗干扰加密扇圆形编解码方法，涉及流通商品防伪追溯技术。该方法将商品信息先进行加密，之后生成扇圆形图喷绘在商品上，使得流通商品上的信息标注具有唯一性、抗干扰性、可追溯性等特点。使用本发明可以提高商品流通的可追溯性和抗干扰性。
