Problems solved by technology
Therefore, limited space becomes a problem when installing such biometric authentication devices in portable terminals such as portable phones or personal digital assistants (PDAs).
In addition, biometric authentication for using facial recognition is performed using visible light images, so authentication accuracy is low
[0006] Also, when using visible light images to perform facial authentication to admit a person into a building, there is a large difference between daytime and nighttime lighting conditions
Therefore, although face authentication is performed by radiating an incandescent lamp to the face at night, the authentication accuracy is lowered
In addition, if a face authentication device is installed in a car to prevent theft of the car, there is a large difference between the lighting conditions during the day and night
Therefore, the authentication accuracy is low

Embodiment Construction
[0053] A preferred embodiment of an infrared (Ir) authentication device will be described, which is used to radiate Ir light and form an Ir image based on the reflected light of the Ir light to perform facial recognition.
[0054]
[0055] FIG. 1A is a schematic diagram of a foldable mobile phone 10. When the foldable mobile phone 10 is opened, a monitor 30 is arranged in the first housing 11 and an input button is arranged in the second housing 12. A camera 110 and four Ir light emitting diodes (LEDs) 60 for emitting Ir rays are arranged on the same surface as the monitor in the first cabinet 11. The camera 110 and the Ir LED 60 are elements of the Ir face authentication device 100 which will be described later. The camera 110 can at least capture infrared light images. If the predetermined input button 40 is pressed, or the foldable mobile phone 10 is opened, the Ir LED 60 and the camera 110 start to operate.

The invention provides infrared (Ir) face identification equipment, a portable terminal comprising the equipment, and safety equipment. The Ir face identification equipment comprises an illuminant for radiating Ir light with the wavelength more than or equal to 760nm to a face; a shooting unit for detecting the reflected light of the Ir light to output Ir images; and an identification unit used for identifying the face by using the Ir images. The Ir face identification equipment comprises a display for displaying the Ir images output from the shooting unit. In addition, the shooting unit and the display are arranged on the same surface.
Description
Technical field [0001] The present invention relates to a face authentication technology that uses infrared images obtained from light reflected by infrared (Ir) light radiated to the face to perform face authentication. Background technique [0002] The methods of authenticating people are roughly divided into three categories. In the first authentication method, belongings such as a key or an identification (ID) card are used. However, in the first authentication method, since the belongings may be lost or stolen, the security is threatened. In the second authentication method, authentication is performed using dedicated information such as a password. However, since the user easily forgets or a third party illegally obtains the dedicated information, security issues may arise. [0003] In a third authentication method that has attracted attention recently, biometric authentication is performed using biometric information (for example, fingerprint, palm, iris, vein, voice, face...
