Governments the world over are watching citizens like never before. But are we any safer for it?

Identification-card holder

March 8 issue - John Daugman will tell you that his most significant inventions are devices that help unscramble brain signals, which proved so useful for neuroscience research that the Queen of England made him an Officer of the Order of the British Empire for his trouble. But that's not what made Daugman popular among venture capitalists and politicians. A decade ago he came up with four mathematical equations that made it possible to "scan" the human iris like a bar code. The technology is so powerful that it could, in theory, make the whole idea of a personal identification card obsolete—your iris could, in effect, be your ID card. All you'd have to do is submit to a quick and harmless laser scan, and the authorities would fill in the blanks from their vast database.
The work seemed interesting enough when Daugman, Bernoulli Professor of Mathematics at Cambridge University, patented it in 1994. But it took on a whole new importance after the terrorist attacks of September 11, 2001. Suddenly iris scanning began to look like a key technology for protecting a frightened Western populace from global terrorism. Since then "biometric" technologies of all flavors—from fingerprint scanners to voice recognition—have taken off, and Daugman's company, Iridian Technologies of New Jersey, is no exception. "Our mission," says the company's Web site, "is to enable a safer world through iris recognition." Its technology is already on show at airports from Japan to Germany to the Netherlands, and Iridian is talking with corporations and government agencies around the world. The prospects are rosy. "This is an industry waiting to happen," says Daugman.
