Food and discussion begins at 12:30 pm. Everyone invited.

Balachander will talk about leakage of Personally Identifiable Information (PII) from Online Social Networks (OSN) and what can be done about it. Aggregators have been tracking user’s Internet movements for a long time and the number of aggregators have shrunk due to economic acquisitions. Aggregators now have the ability to link tracking information with PII on OSNs. Public policy is still being formulated and cooperation from aggregators may be necessary to ensure privacy protection.
