Title: WING Special Meeting - Economics of online personal information:  
 From users to markets
Speaker: Vijay Erramilli

Online services are largely fueled by the collection and exploitation of  
personally identifiable information (PII) . Online entities collect PII of  
users in exchange for services and these entities monetize this data  
primarily via advertisements. Information aggregators (; 3rd party  
aggregators like DoubleClick and online applications like Google, Facebook,  
Groupon etc.) have found new ways to collect and exploit this data.  On one  
end, as aggregators move into monetizing more of this PII, they end up  
crossing the `creepiness' line, antagonizing end-users and opening the door  
to a barrage of bad press and potential legislation.  On the other end,  
proposed solutions to preserve privacy have failed to be adopted for a  
variety of reasons, while the situation has worsened on the ground with  
leakage being compounded with linkage. Attempts to provide strong privacy  
guarantees (e.g., differential privacy) undermine the utility of the  
aggregators, enforcing constraints and hence decreasing the chance of  
adoption. It would appear that this tug-of-war between users on one-end and  
aggregators on the other is hard to resolve.

In the first part of the talk, I will describe work done on understanding  
the perceptions of users with regards to their personal information, with  
emphasis on the economic exploitation of their information. Previous work  
in this domain relied on surveys that fail to capture context. I will  
describe a methodology based on experience sampling that captures context  
of users and an auction-based game to get users to valuate their personal  
information in online settings. I will discuss results of a user study  
consisting of 168 users and their implications.

In the second part of the talk, I will describe transactional privacy (TP),  
a mechanism that facilitates information release by users for adequate  
monetary compensation. TP forms the core of personal information markets, a  
system wherein users can opt-in and put up PII of their choice up for sale,  
while aggregators can 'purchase' this PII and exploit it as they see fit. I  
will describe the various components of TP and how such a system can help  
address the tug-of-war between users and aggregators over PII.
