Abstract: Security systems for secured assets such as vehicles, are described in which facial recognition systems or other biometrics systems provide enhanced security for an authorized user. Subtle or covert cues provided by the user during authentication or subsequent monitoring of the user by the facial recognition system and other input systems are used to invoke user-editable personal security rules that respond to the cues to implement the user's desired responses for added security in various situations. Related security systems, methods, and devices are described to protect an asset such as an automobile or other vehicle or other secured asset through the use of biometrics and personal security rules. In such systems, a training module may provide periodic training and practice sessions to assist the user in being prepared to properly use the personal rules system in response to various scenarios and threats, and can guide adjustment of personal rules for better success.
