Caveon already has branched out a bit, forming a joint venture called Kryterion with Dutch educational testing company Cito and Toronto-based human resources recruitment company Drake International. Kryterion (www.kryteriononline.com) allows people to take tests securely via the Internet from any location. "After five or six questions, we know if it's a valid test," Foster said.

As for Caveon, Foster expects the company in five years to have hundreds of employees and revenues approaching $100 million. He expects it to serve international markets "where the problems are no less than what we have in the U.S."

"We've just scratched the surface of our own technologies to fight cheating. These things we've come up with are somewhat crude compared to what we'll have in five years," Foster said.

"Anytime you're in an industry where nothing has been done for a hundred years, there's so much that can be done — with the Internet, with technology, with analyses. The world just opens up, and that's what's waiting for Caveon."
