Abstract

The technological advancements in Internet speeds, increased computing power and smart phones have pushed the rise of new digital methods supporting mobile person-to-person (P2P) payments. Despite the growing interest in these new methods, we be-lieve that, to fully enable this increasing rise of digital wallets, there is the need for tools helping a person in judging the risk of a money transfer. For this purpose, this paper aims at exploiting social net-work connections. This is achieved by making pay-ers/payees able to state their trust preferences with respect to the potential payees/payers. Trust pref-erence evaluation requires to find social connections between a payer and a payee across, possible, differ-ent social network realms. We therefore propose a light cryptography protocol, specifically targeted to mobile P2P payments, that besides providing good performance, ensures user information privacy.
