Saturday, July 10, 2004: 11:00 am (Area "B"): This will be a talk on how databases can do useful work and serve society without storing any personal information. For the past several years, Peter Wayner has been exploring how banks, stores, and businesses everywhere can offer their customers personalized service without keeping personal data about them where it can be abused by nefarious insiders or malicious outsiders. Building these systems requires more of a change in attitude than a change in technology because all of the solutions use standard encryption tools as a foundation. Topics will include how to build these systems and when they can help make the world a safer, saner place.
