Presentation outline

● Motivations● Introduction● Features● FOAFRealm● D-FOAF● Final Remarks● Future Works

3

Motivations

• Current solutions offers only a static predefined access control

• Management is often limited to storing login and password

• Existing solutions are usually centralized and not based on open standards

• Users are bored after submitting the same information for so many times during the registration process

4

Introduction

• User profiles management system based on FOAF

5

Introduction

• Policies expressed by social networking– Friendship level between owner and requester, calculated across

social network's digraph

6

Features

• Accessible through SOA interface

– .NET, PHP and J2ME clients exists

• Distributed identity management (D-FOAF) based on hypercube-based network– The HyperCuP protocol

• Support for single registration and Single Sign-on

• Distributed solution based on open standards

7

FOAFRealm Architecture

• RDF storage independent

• Can be adapted to environments other than Jakarta Tomcat

8

D-FOAF

• Distributed FOAFRealm

• Distributed friendship level computation

• Single Sign-on and Single Registration within distributed FOAFRealm servers

9

D-FOAF architecture

• P2P based on the HyperCuP protocol

10

Conclusions

• Providing distributed user profile management system based on open standards will deliver users more control over their profile information

• With access control based on social networks definition it is possible to model fine-grained access control restrictions

11

Future works

• Novel and flexible architecture

• Fancy and user-friendly GUI

• Well documented

• Supports users' roles
