FYI, and as he's too shy to make the announcement himself, let me tell
you that Andrei Vlad Sambra will be defending his PhD thesis on Tuesday
November 19th 2013, at Telecom SudParis (Évry, France), on the suject of
"Data Ownership and Interoperability for a Decentralized Social Semantic

Let's wish him good luck for the final sprint ;-)

Below's a copy of the announcement (removed the abstract in french).

Best regards

 Ensuring personal data ownership and interoperability for decentralized 
 social Web applications is currently a debated topic, especially when 
 taking into consideration the aspects of privacy and access control. 
 Since the user's data are such an important asset of the current 
 business models for most social Websites, companies have no incentive to 
 share data among each other or to offer users real ownership of their 
 own data in terms of control and transparency of data usage. We have 
 concluded therefore that it is important to improve the social Web in 
 such a way that it allows for viable business models while still being 
 able to provide increased data ownership and data interoperability 
 compared to the current situation.

 To this regard, we have focused our research on three different topics: 
 identity, authentication and access control. First, we tackle the 
 subject of decentralized identity by proposing a new Web standard called 
 "Web Identity and Discovery" (WebID), which offers a simple and 
 universal identification mechanism that is distributed and openly 
 extensible. Next, we move to the topic of authentication where we 
 propose WebID-TLS, a decentralized authentication protocol that enables 
 secure, efficient and user friendly authentication on the Web by 
 allowing people to login using client certificates and without relying 
 on Certification Authorities. We also extend the WebID-TLS protocol, 
 offering delegated authentication and access delegation. Finally we 
 present our last contribution, the Social Access Control Service, which 
 serves to protect the privacy of Linked Data resources generated by 
 users (e.g. profile data, wall posts, conversations, etc.) by applying 
 two social metrics: the "social proximity distance" and "social  contexts".

 Keywords: Web, decentralized identity, decentralized authentication, 
 privacy, access control, WebID, WebID-TLS
