And a smart key 20 provided with an in-vehicle driver authentication device 10 and an authentication information storage unit 21 and a second short range wireless communication unit 22.

First, referring to the in-vehicle driver authentication apparatus 10, the image capturing unit 11 captures a face image of a driver sitting in a driver's seat in a vehicle. In one example, an infrared camera is included.

The first short range wireless communication unit 12 communicates with the second short range wireless communication unit 22 of the smart key 20 under the control of the driver authentication unit 14 to obtain driver's authentication information from the smart key 20.

The image storage unit 13 stores the image photographed by the image capturing unit 11 under the control of the driver authentication unit 14.

The driver authentication unit 14 authenticates the image photographed by the image capturing unit 11 based on the driver's authentication information obtained from the smart key 20 and permits starting of the vehicle when the driver is a normal driver. In this case, the captured driver's image is stored in the image storage unit 13. The stored image is provided as a clue to detect an illegal intruder so that a normal driver can check it later.

In addition, the driver authentication unit 14 is smart when a user inputs a password for editing (adding, correcting, deleting, etc.) authentication information from a user through a human machine interface (HMI) (not shown). The user is authenticated compared to the password set in the key 20. At this time, the password is encrypted and processed.

When authentication is normally processed, the driver authentication unit 14 transmits the authentication information, which is a standard for authenticating the driver, to the smart key 20 through short-range wireless communication so that the authentication information is stored in the authentication information storage unit 21.

Such a function may solve a cumbersome process in which each user visits a vehicle provider and registers a plurality of authentication information in one smart key 20 when a plurality of users operate a vehicle.

Next, referring to the smart key 20, the authentication information storage unit 21 stores the authentication information that is a reference for the driver's authentication. At this time, the authentication information is stored in a list form and includes at least one authentication information.

This mount is configured.

The feature extractor is mathematically based on the Principal Component Analysis (PCA) of the multivariate analysis method, which extracts feature values that can be distinguished by reflecting individual features well in various changes such as facial expressions and changes in time. An extraction program for extracting the feature vectors having the feature vectors and then normalizing the feature vectors is installed.

The identity discriminator is based on a support vector machine (SVM) that classifies classes by finding the optimal separation hyperplane (Maximum) that maximizes the distance between two classes to efficiently classify and retrieve large spatial data with only a small number of training data. Mounted.
