Electronic key system
First Claim
1. An electronic key system comprising:
- a control unit mounted on an automobile to provide an operational instruction to the automobile,a portable device configured to be worn on and carried by a body region of a user and including at least a biometric recognition sensor configured to detect biometric information of the user,a registered biometric information storage unit configured to store biometric information of a previously-registered user; and
a biometric authentication unit configured to determine whether or not biometric information of the user detected by the biometric recognition sensor is matched with the previously-registered biometric information of the user stored in the registered biometric information storage unit,whereinthe control unit includes an imaging device, an image recognition unit and an operation control unit,authentication between the portable device and the control unit is established when the user is authorized as the registered user by the biometric authentication unit, andwhile the authentication is established, the imaging device images an action of a region of the user inside the automobile, the image recognition unit detects a specific action of the region of the user based on the image information from the imaging device, and the operation control unit controls an operation of the automobile in accordance with the specific action of the region of the user detected by the image recognition unit.

Abstract
Provided is an electronic key system capable of providing an instruction to an automobile through a portable device having biometric authentication of a user. When biometric information of a wearer is detected by a biometric recognition sensor, a portable device worn on a user determines with a biometric authentication unit whether or not the detected biometric information is matched with biometric information of a previously-registered user. When the biometric authentication unit authorizes that the wearer is a registered user, the portable device enables, through a communication control unit, near-distance wireless communication with a control unit mounted on an automobile through a wireless communication device. Thus, the portable device can provide an operational instruction to the automobile through wireless communication with the control unit.
