An Improved E-Payment System and Its Extension to a Payment System for Visually Impaired and Blind People with User Anonymity

An Improved E-Payment System and Its Extension to a Payment System for Visually Impaired and... Electronic payment systems have become increasingly popular due to the widespread use of the internet-based shopping and banking. Such systems should at least guarantee users’ anonymity during the transaction, fair exchange of goods and offer dispute resolutions. As many of the electronic payments are nowadays performed on mobile devices, also efficiency with respect to communication and computation costs at the user’s side is another important requirement. In this paper we first show that a previously proposed system does not offer the claimed anonymity and non repudiation features. These issues are based on problems in the underlying authenticated encryption scheme. We propose an alternative system that satisfies all the required security features. In addition, we show how similar techniques can be applied to develop a payment system on a vending machine or in a retail outlet for the user using its smartphone as proxy, allowing besides confidentiality and authentication, also user anonymity throughout the whole process. This payment system is in particular of interest for blind or visually impaired people, who become able to take the whole payment process in own hands, instead of being dependent of the payment device and the possibly untrusted environment. Both payment systems apply the anonymous signcryption scheme ASEC as building block. Wireless Personal Communications Springer Journals
