TWeD Talk: HTTPA: HTTP with AccountabilityMarch 31, 2014
There's always something happening on Wednesday evenings in the Tetherless World!

TWeD Talk, Wednesday, April 02, 2014, 7pm ET, Winslow Building on the RPI Campus

Please join as MIT CSAIL Ph.D. student Oshani Seneviratne leads us in a discussion of some of her current work investigating protocols for accountability on the Web!

ABSTRACT: We have developed HTTPA, an architecture for the Web to address complex issues arising from data reuse. These issues include privacy violations and intellectual property rights violations. This talk will present the motivation for HTTPA based on results from a policy awareness study and some initial tools such as the License Usage Validator, and the Semantic Clipboard. These tools are limited to a particular type of content reuse, i.e. image reuse. Therefore, we extended our work to include policy awareness on any resource on the Web using HTTPA. HTTPA is built on open Web standards and uses the 'Provenance Tracking Network' (PTN), an open global trusted network of peer servers that logs resource usage data. Websites that conform to the architecture communicate information about transactions for any sensitive data items with the PTN. These logs can later be queried to check compliance with individual, organizational, state or federal policy and usage restrictions that assert no unauthorized data transfer or usage has taken place. We have evaluated this architecture using an electronic healthcare records application called Transparent Health that gives patients a better sense of how their sensitive data has been used.
