A mobile payment evaluation based on a digital identity representation

In today´s interconnected world, the mobile phone, especially the smartphone, takes a central place. Recently, the NFC technology has been embedded in smartphones to enable new usages such as mobile proximity payment. Meanwhile, growing concerns have raised regarding the privacy issues of those technologies. In this paper, we propose a new way to analyze the privacy issues of NFC payment. The payment is modelized as a digital identity of the customer and the payment process is viewed as a identity management solution (IMS). A specific framework designed to analyze privacy and security in IMS is then applied to make the analysis.
