Preventing Counterfeit Products using Cryptography, QR Code and Webservice

Counterfeit production is a threat for every genuine business causing damage to their brand image and stealing revenues. The aim of this paper topresenta novel method prevent counterfeit products using cryptography, QR code webservice. requires that original product manufacturer obtain cryptographic key pair, securely store private publish public on website as code. needs print unique item packs provide inside the pack encoding ciphertext generated by encrypting with key. For verification buyers, manufacture required scanning app download website, Google Play Store or iPhone App Store. should have additional functionality decrypt encoded in also launch simple webservice his hosting server accept requests from mobile verify buyer’s name its database. Technicalimplementation process are described detail through figures flowchart. can be implemented even small manufacturers nominal cost obtaining pair creating webservices. We tested an actual software written operations Java cryptography Extension Zxing libraries.
