Paying with a selfie: A hybrid micro-payment framework based on visual cryptography

Abstract

In developing countries, the mobile revolution is happening in these days, and technology is now improving life conditions and providing new opportunities for the developing of the economies. In this paper, we provide a micropayment framework that can be used to conclude everyday financial transactions. The novelty of the approach relies on the usage of techniques of easy understanding and application, even for uncultured people. The security of the system is also ensured by exploiting visual cryptography schemes, whose reconstruction phase requires no particular technical skills and relies only on human activities. The description of usage scenarios and the prototypal architecture of the framework are provided together with the initial plan for the experimental deployment.
