Towards More Secure Cardholder Verification in Payment Systems

This paper introduces a new cardholder verification method using a multi possession-factor authentication with a distance bounding technique. It adds an extra level of security to the verification process and utilizes the idea of distance bounding which prevents many different security attacks. The proposed method gives the user the flexibility to add one or more extra devices and select the appropriate security level. This paper argues that the proposed method mitigates or removes many popular security attacks that are claimed to be effective in current card based payment systems, and it can help to reduce fraud on payment cards. Furthermore, the proposed method provides an alternative verification technique and enables cardholders with special needs to use the payment cards and make the payment system more accessible.
