现在产品假冒伪劣问题随着科技发展而层出不穷，目前假冒伪劣对象主要针对名贵烟酒、高档服饰、奢侈品以及一些著名品牌的产品等。很多假冒伪劣产品采用原装正品用过的包装盒/瓶进行伪装，混淆消费者的视线，达到以假乱真的目的。同时在现有技术中，智能手机随着科学技术的发展日新月异，在市场上智能手机占有率比重越来越高，逐步取代功能手机；功能上智能手机逐步实现个人计算机具有的功能；智能手机受消费者的追捧，普及率越来越高。Nowadays, with the development of science and technology, the problem of counterfeit and shoddy products is emerging one after another. At present, the targets of counterfeit and shoddy products are mainly targeted at expensive tobacco and alcohol, high-end clothing, luxury goods and some famous brand products. Many counterfeit and shoddy products are disguised with used packaging boxes/bottles of original genuine products to confuse consumers and achieve the purpose of confusing the real ones. At the same time, in the existing technology, with the development of science and technology, smart phones are taking a higher and higher share in the market, gradually replacing feature phones; in terms of functions, smart phones gradually realize the functions that personal computers have; The popularity of consumers is getting higher and higher.
现有的产品防伪查询服务系统有针对产品真假鉴别，如果采用人工对防伪码进行查询，尤其是老年人出错率极高，导致消费者都不愿意进行真伪查询,效率低。The existing product anti-counterfeiting query service system is aimed at identifying the authenticity of the product. If the anti-counterfeiting code is manually checked, especially the elderly, the error rate is extremely high, which makes consumers unwilling to check the authenticity, and the efficiency is low.
现有技术中，防伪查询终端服务器的数据库形成方法落后，使得企业用户的生产效率低下。In the prior art, the database formation method of the anti-counterfeit query terminal server is backward, which makes the production efficiency of enterprise users low.
