FUJITSU has developed an iris authentication system and built it into a prototype smartphone.
The next-generation authentication method activates automatically when the user looks at the smartphone’s screen, instantaneously reading the iris and unlocking the phone.
Currently, smartphones typically use either a password or fingerprint scan to unlock the screen or for other authentication purposes. Fujitsu’s new authentication method uses iris recognition, which is hard to forge and also enables hands-free authentication.
By making authentication easier, Fujitsu says it reduces the barrier to the usage of security features.
According to Fujitsu, it will also develop systems to allow iris authentication to be used to log into web services without having to input an ID or password, enabling simple and secure access.
The Fujitsu system shines an infrared LED light on the eyes of the user, then captures an image of them using an IR camera, acquiring the iris pattern, which is registered and used to verify matches.
Previously, iris authentication systems were too big or too slow to be used in smart phones. Fujitsu developed a custom compact and high-output infrared LED, and a custom infrared camera, and combined them with camera controller technology and biometric-authentication technology. The solution also uses Delta ID’s ActiveIRIS, a high speed, high reliability iris recognition engine, which allows it to be used at a normal smartphone viewing distance.
In standard photobiological safety testing (IEC 62471), the infrared LED light was verified to be safe for the eyes.
