Digital Certificate Based Security Payment for QR Code Applications

Abstract

A rapidly growing social interaction technology is the use of Quick Response (QR) codes as physical entrances (i.e. the encoded URL address) to Internet resources. However, there exist various kind of security problems, for example, the URL may point to some phishing web sites. A digital certificate based signature and verification QR code is proposed in this paper. The public and private keys are generated by the authentication mechanism, which using the Public Key Infrastructure (PKI) technology. The public key can be published with the designed scanning application (App). An authenticated QR code can be created based on the private key and the merchant information. Clients can authenticate the codes by the public key and scanning App. Test results prove that the security QR code designed by this system, which binds the digital certificate, can be verified by the decoding scanner.
