178 Toshiba Utilities Fingerprint Authentication Utility ❖ Error reading fingerprint-the movement was skewed. Swipe your finger again in a straight line. ❖ Error reading fingerprint-the movement was too fast. Swipe your finger again at a slower speed. ❖ Error reading fingerprint-the movement was too short. Swipe your finger again using a longer motion. Fingerprint Logon The fingerprint utility enables logon to your computer using fingerprints. During user enrollment, fingerprint samples are saved and associated with the user's Windows® user account. When the user attempts to log on again, the user's fingerprint is read and compared with the user's enrolled fingerprints; if the fingerprint is recognized, user logon is completed. The Fast User Switching feature of Windows® XP is also supported. If user A is logged on and the fingerprint utility verifies the fingerprint of user B (who is already enrolled), the utility recognizes the fingerprint and switches the users. If your system supports power-on security, existing fingerprint samples can be used also for power-on authentication. Power-on Security The power-on security feature prevents unauthorized access to your computer when it is turned off by requiring the user to pass fingerprint authentication. If fingerprint authentication fails, the user will not be able to start the computer. When power-on security is enabled, the system asks you to authenticate your fingerprint. You have 40 seconds to swipe your fingerprint. If the authentication fails, the system tries again up to two more times. If authentication fails after the third attempt, the system shuts down.
