Customized Views on Profiles in WebID-Based Distributed Social Networks

Abstract

WebID as an extensible and distributed identification approach enables users to globally authenticate themselves, connect to each other and manage their identity data at a self-defined place. Identity data stored in WebID profile documents can be protected from unauthorized access using appropriate access control methods. While existing methods are primarily about securing resources, they lack providing adequate mechanisms for controlling access to specific data within profiles. This paper presents our approach to create customized views on profiles in WebID-based distributed social networks. We introduce finegrained personalized filters based on SPARQL templates and demonstrate their integration into an existing identity management platform.

Towards a Context-Aware WebID Certificate Creation Taking Individual Conditions and Trust Needs into Account

“…Users should therefore host their WebID profiles only on servers they either own or trust, and protect it from unauthorized access. As a consequence, it seems logical to run an own server hosting the WebID profile or, at least, use a hosted WebID identity provider and management platform, like proposed in [26]. This would compensate the private key secrecy drawback, which does not exist when using the client-side or the hybrid generation mode because the private key is kept safe from unwanted disclosure.…”

“…As a WebID identity provider integrating the CaWICC approach, we use Sociddea [26]. With Sociddea, a user can automatically create a new WebID, a WebID profile, and a WebID certificate.…”

“…While FOAF is an ontology for personal data, also other vocabularies -that can be expressed via RDF -are allowed. A semantic description like this facilitates a controlled exploitation of profile data in order to optimize customer services or create an improved user experience, e.g., through applying customizations specific to the authenticated user [26].…”

“…However, these tools are primarily intended for technically experienced computer users that are familiar with using command line interfaces. In order to address a larger group of users, there are also specialized Web applications available, like proposed in [26]. They can automatically generate all necessary WebID artifacts, including WebID certificates, based on a user's form inputs on a Web page.…”

Collaborative adaptive case management with linked data

“…They contain an identity owner's personal data described in a machine-readable way using Linked Data. With WebID, users are enabled to globally authenticate themselves, connect to each other, manage their profile data at a self-defined place and specify customized views [10]. In order to accommodate the data for a) within a WebID profile we introduce the following vocabulary: The RDF property vsrcm:experiencedIn connects a foaf:Person with a URI which represents this person's experience in something.…”
