Mobile phones have become an integral part of a vast majority of people’s daily lives. It is becoming rare to conduct any form of communication between individuals without a mobile phone. Research continues on the integration of mobile phones and e-commerce solutions. Developed countries already use systems for such commercial transactions however developing countries, for example those in the ...

We present in this paper a method to analyze the security problems which can occur in a NFC mobile phone payment. In the first section, we give a simplified description of the technical realization for this pilot limited to a part of the system. In the second section, we present the security concepts as a major issue in this scenario. Roughly main requirement is to have same level of security a...

Distance-Bounding is used to defeat relay attacks. For wireless payment systems, the payment terminal is not always online. So, the protocol must rely on a public key for the prover (payer). We propose a generic transformation of a (weakly secure) symmetric distance bounding protocol which has no postverification into wide-strong-private and secure public-key distance bounding.

This work presents a prototype implementation of a smartphone as secure eID reader using NFC technology. The presented approach aims to reach a security level close to standalone smart card readers. This security level will be allowed by the means of a trusted execution environment (TEE) which allows strong isolation and separation for critical applications and provides trusted, not interceptab...

Smart cards are being integrated into a diverse range of industries: ranging from banking, telecom, transport, home/office access control to health and E-passport. Traditionally, cardholders are required to carry a smart card for each application. However, recent developments in the Near Field Communication (NFC) have renewed the interest in multiple applications for different services on a sin...

The main objective of this paper is improving the BOAT classification algorithm and applying it in credit card big data analysis. Decision tree algorithm is a data analysis method for the classification which can be used to describe the extract important data class models or predict future data trends. The BOAT algorithm can reduce the data during reading and writing the operations, the improve...

Near-elderly individuals, those 60 to 64 years old, have high health care needs and, if uninsured, often delay costly care until they enroll in Medicare (Card et al. (2008); McWilliams et al. (2009)). The passage of the Affordable Care Act (ACA) in 2014 provided new coverage options to uninsured near-elderly individuals. Although understanding the extent to which the ACA affected the near-elder...

Near field communication has enabled customers to put their credit cards into a smartphone and use the phone for credit card transaction. But EMV contactless payment allows unauthorized readers to access credit cards. Besides, in offline transaction, a merchant's reader cannot verify whether a card has been revoked. Therefore, we propose an EMV-compatible payment protocol to mitigate the transa...
