The rise of biometric systems in mobile devices is creating a great deal of interest as well as criticism from those who feel they are lacking in security.
To shed more light on the biometric system used in their devices, the Touch ID, American company Apple published a white paper outlining how the system works.
According to the white paper, the sensor can recognize as many as five different fingers, but the fingerprint data is not made available to other third-party applications.
«With one finger enrolled, the chance of a random match with someone else is 1 in 50,000. However, Touch ID allows only five unsuccessful fingerprint match attempts before the user is required to enter a passcode to obtain access.”
