An e-payment architecture ensuring a high level of privacy protection

Abstract

Online shopping is becoming more and more interesting for clients because of the ease of use and the large choice of products. As a consequence, 2.3 billion online clients have been identified in 2011. This rapid increase was accompagnied by various frauds, including stolen smart cards or fraudulent repudiation. Several e-payment systems have been proposed to reduce these security threats and the 3D-Secure protocol is becoming a standard for the payment on the Internet. Nevertheless, this protocol has not been studied in-depth, particularly in terms of privacy. This paper proposes a detailed description and an analysis of the 3D-Secure protocol, through a new privacy-orienting model for e-payment architectures. Some improvements of 3D-Secure protocol, concerning the protection of banking information, are also presented. Then, this article presents and analyses a new online payment architecture centered on the privacy of individuals.
