Secure Data Storage and Exchange with a Private Wallet

Abstract

Sharing private data between various users is a daily scene. The owner has both rights at the same time, the right of a self-determined and the right of a policed usage of his private data by foreign holders. We develop an approach that allows an owner to store and share his private data and gain full control about the usage of his private data. Therefore, we develop and implement a flexible system that uses a peer-to-peer architecture and modern encryption standards to realize data privacy. We call this system private wallet. © Springer International Publishing Switzerland 2015.
