The Application Of Anti-counterfeiting Technology Based On Hash Encryption Algorithms For Two-dimensional Code Products

With the development of electronic commerce,the shopping mode is having a fundamental change and the online volume of business is increasing progressively.But because E-commerce network platform do not manage strictly on resource and merchant and the opening cost is very low,also there is no direct contact between the client and the merchant,these factors have provided a vast,convenient space for the merchant and individuals that sell counterfeit and shoddy products.Anti-fake,as a way to redeem cooperation reputation and protect consumer rights and interests,has become one of the focus issues of enterprises and the whole country.A great number of labor power and material resources have been spent on cracking down counterfeit and shoddy products.The traditional anti-fake is mainly limited to physical anti-fake.But with the development of printing technology,counterfeiting label is not a difficult problems any more.As for consumers,they do not have enough professional knowledge to identify true and fake labels.Therefore,even enterprises have made great efforts to strengthen anti-counterfeiting power,there are still many fakes.How to truly achieve anti-counterfeiting is a main issue that many enterprises and researches focus on.Through meticulous study,it was found the reason that traditional anti-fake can not put an end to fakes is that it does not have a loop-locked certification system.That is,the anti-fake label does not have a feedback process since it is sent out,so this is a loophole that can be used by counterfeiters.With the rapid development of communication technology and popularization of smart phones,two-dimension Code is widely Applied on market.Because two-dimension Code has the characteristics of high-density coding,high fault-tolerant ability,high coding reliability,low cost,easy to be made and easy to be recognized by cellphone,it has a good and natural anti-fake ability.This article will make use of the features of two-dimension Code and combine Hash encryption algorithm to design relative anti-fake system.This system will generate a unique Code and electronic identity card of commodity for every product.After users buying this product,they can feed back the product Code to the system only by simple scanning,and the system will judge if this Code is right and the scanning times and time through decryption technology,so as to feed back the identification information of product.This system has achieved features of uniqueness,impossible to be modelled on,impossible to copy,preventing fake identification and low cost of product anti-counterfeit label,and has truly achieved the effect of anti-fake.Through investigation and survey on market,it also achieved anti-fleeing goods on the basis of anti-fake and has maintained the benefits of enterprises and dealers.
