Minnetonka-based Visionics Corporation is on a roll. The company, which makes tools for identifying people through their physical features, has seen its stock price soar since September 11th. Visionics has found many new customers for its fingerprint and facial recognition software. Its contoversial Face-It product is being tested in major airports like Boston's Logan International, and is being installed right now in two undisclosed U.S. international airports. But privacy advocates don't like Face-It; other critics say it just doesn't work well enough to identify terrorists in public places like airports. Computer security consultant Richard Smith did his own tests on Face-It and found it easy to fool.
