Summary:
Whether it's checking stock prices, looking up government information or booking a flight, we're relying more and more on information provided over the Internet from electronic databases. But if hackers break into those databases, they could remove files or plant false information, potentially causing huge financial losses. University of California, Davis, computer scientists are working on the Truthsayer project which lets computers go on providing useful, accurate information, even though they are open to attack by hackers.

Whether it's checking stock prices, looking up government information or booking a flight, we're relying more and more on information provided over the Internet from electronic databases. But if hackers break into those databases, they could remove files or plant false information, potentially causing huge financial losses. University of California, Davis, computer scientists are working on the Truthsayer project which lets computers go on providing useful, accurate information, even though they are open to attack by hackers. In the Truthsayer system, developed by Premkumar Devanbu, Michael Gertz, Charles Martell and Phil Rogaway at UC Davis and independent consultant Stuart Stubblebine, the original database is kept on a "trusted" computer which is not connected to the Internet. Copies of the database are given out to other computers which publish it on the Internet, along with a digital signature from the trusted computer.
