Cheap Solution for Security

A Brisbane man has invented a simple, low-cost online authentication system that would allow banks to offer one-time passcode security to all their customers. Internet database manager Matthew Walker has won a patent for PassWindow, which synchronises a part-pattern printed on a see-through card window with the rest of a unique pattern generated on the computer screen to display a numeric code. Online users hold their card against the screen to reveal a randomly created six-digit number that securely authenticates their financial transactions. Mr Walker said PassWindow did the same job as hardware tokens but for almost no cost, so banks could offer that level of security to all customers, rather than just their high-wealth or business clients
