SQAMPS: Secure Quorum Architecture for Mobile Presence Services with End-to-End Encryption

The use of social networking applications has been multiplied hugely in the last decade. Social networking applications build upon the mobile presence services to enable human communications over a distance in real or non-real time. Presence enabled applications enable to publish and retrieve the context information such as online/offline standing, GPS location and updates created by buddies enlisted in a buddy list. If such presence enabled updates occur o updates occur, this would result in a measurability downside for the backend servers. This paper addresses measurability issue, proposes a novel architecture for mobile presence services (SQAMPS) that is security enabled (i.e., end-user security, server authentication and media file security) and allows for decreasing the search latency and price. SQAMPS implements a hybrid end-to-end cryptography scheme, a distributed trust system and distribution access rights to the media file area unit.
