The document discusses key opportunities and challenges for the next generation internet (NGI) around identity, anonymity, and trust. It identifies two priorities: enabling identity to guarantee who or what someone claims to be, and enabling anonymity to guarantee only minimum information is revealed. Solutions around data and identity management are discussed, along with technologies driving the NGI like pervasive connectivity, the web as an applications platform, and cloud computing. The NGI is seen as co-evolving with society in areas like social networks, requiring the new discipline of web science.

4. The Internet is Great but … Not all things are right, the future is not guaranteed What needs fixing? What needs doing? What needs leaving alone? Next-generation Internet

5. Identity, Anonymity and Trust

6. Internet is a social system The NGI consists of people, not machines People are the nodes and active agents. Web2.0  every consumer is a producer. If we can’t safeguard the identity of users, the whole thing falls apart. Dig Econ principle: Participation is proportional to trust. Economy:money::Internet:identity_token

7. Two Priorities Enabling Identity Guarantee that you are who or what you claim to be. Enabling Anonymity Guarantee that no more than the minimum info required is revealed. Trust is the measure of both What am I prepared to reveal to this resource? What I need to reveal to this resource?

8. Solutions No intervention, Free market BUT: Lose the integration possibilities, i.e. no NGI Do we allow the majors (inc. government) to take over? Data and Identity Management The BBC solution The distributed solution

10. Headlines Pervasive connectivity Not just higher bandwidth to the few, but some bandwidth to the many Web as an applications infrastructure Cloud Computing Resource Oriented Architectures Data liberated from application silos Linked data Obama announcement Co-evolution with society Web 2.0 is about people Web Science

11. Pervasive Connectivity Two distinct effects: Greater bandwidth – affords new capability Greater connectivity – more people more often The increasing participation in the digital world is the single most powerful new effect in distributed systems Our students don’t remember life without the Web / without Google – what will the next generation bring ?

12. Web - an applications infrastructure Shift away from desktop applications installed locally by user or system administrator Shift toward browser-based apps which don’t make your disk dirty, and apps on mobile devices Perpetual beta web sites are agile Ease of use and ease of development The SOA versus ROA debate – the Web is simply the most scalable most usable distributed system ever Access cloud resources Beware that cloud is not a silver bullet, we are in an evolving ecosystem

13. Data liberated from application silos Linked Data guidelines make data more reusable – a Web of Data, not just a Web of documents Data providers are beginning to publish in Semantic Web format (RDF) See linked data cloud picture (next slide) e.g. Obama’s use of Semantic Web

15. Co-evolution with society Don’t just think technology drivers, infrastructure or service provision The Web (infrastructure, content and applications) is an evolving organism and it is co-evolving with society that uses it Compare with Web 2.0 – not a new architecture but a set of observations on how the Web is actually used Need to look at micro and macro effects e.g. Social network analysis and theories This is the new discipline of Web Science
