Using the Same PayWord Chains Associated with a Single Account from Multiple Mobile Devices

Abstract EN

Customer awareness and interest in mobile payments are increasing.

However, security and privacy risks remain major barriers to their adoption, with customers worrying about their personal data being hacked or intercepted.

In this paper, we present the design of a secure scheme for mobile payments that can guarantee mutual nonrepudiation between the customer, merchant, and banker.

A customer can use the proposed scheme to make a payment with the same PayWord chains of a single account from multiple devices.
