This paper presents a context-aware and decentralized identity platform, which in turn can be used to create social networks or collaboration platforms. Its originality lies in providing an increased privacy and control over a user's online identity, user group management, resource ownership and content sharing. This paper addresses the shortcomings of current identity and resource management systems, especially the lack of context in which data sharing takes place on the Internet. Moreover, it discusses the advantages for users to have a decentralized resource management system, while at the same time remaining in control of the data they share, as well as the device on which it is stored.
