PhD project Sociddea

Sociddea is a WebID identity provider and management system. With Sociddea, users can automatically create new WebIDs, underlying WebID profiles and associated client certificates. The system allows users for hosting their WebID profiles in the ecosystem provided by Sociddea. Yet, there is no need to do this, i.e., users can also create new client certificates for profiles hosted somewhere else. Sociddea users benefit from hosting their identity data on the system in that they are assisted in carrying out various tasks related to their WebID-based identity. Users can also easily connect to each other via drag and drop of WebIDs. A graphical editor eases adding and modifying profile information. Sociddea supports profile owners in protecting their identity data from unwanted retrieval, malicious manipulation and improper use. The system is built using Microsoft's ASP.NET MVC5 framework.
