A method for deterring unauthorized use of an electronic device is described. The method includes installing security data in a protected storage area, installing a security routine operable to check for the security data, and prompting a user for identity information if the security data is found, before permitting use of the device. In an implementation, the device is shut down if the identity information is incorrect, and manufacturer contact information may be displayed before shutting down. But if the user responds correctly, the activation process is continued to enable normal operation of the device.
