Face authenticating apparatus, face authenticating method, and program
View Patent ↗The present invention provides a technique for preventing an unauthorized user from using a terminal and ensuring secure use of the terminal. A presentation pattern display unit 5 that is provided at a different position from a key input unit displays an instruction for a user to input a key pattern during face authentication, and a built-in camera 1 captures a face of the user and/or a movement of a portion of the face of the user during a portion of or the entire time from when the presentation pattern display unit 5 displays the instruction to when the key input through the key input unit 10 is completed, so that it is determined whether the captured face image is of a living body.
1. A face authenticating apparatus comprising:
allowing a presentation pattern display unit that is provided at a different position from a key input unit to display an instruction for a user to input a key pattern during face authentication;
allowing an image capturing unit to capture a face of a user and/or a movement of a portion of the face of the user during a portion of or the entire time from when the presentation pattern display unit displays the instruction to when the key input is completed; and
determining whether the captured face image is of a living body,
wherein the presentation pattern display unit displays an instruction to see the image capturing unit while the user alternately views the presentation pattern display unit and the key input unit.
2. The face authenticating apparatus according to claim 1 , wherein the presentation pattern display unit is separated from the key input unit in the vertical direction.
3. The face authenticating apparatus according to claim 1 , wherein the presentation pattern display unit displays a portion of the instruction, detects an input timing to the key input unit, and displays the other portion of the instruction after the input is confirmed.
4. The face authenticating apparatus according to claim 1 , wherein the presentation pattern display unit displays a keypad including random numbers arranged thereon to allow the user to input keys corresponding to the arrangement using the key input unit.
5. The face authenticating apparatus according to claim 1 , wherein the face authenticating apparatus determines whether, after a rational time has elapsed after the presentation pattern display unit displays a predetermined instruction, a key input corresponding to the instruction is performed on the key input unit.
6. A face authenticating method comprising:
allowing a presentation pattern display unit that is provided at a different position from a key input unit to display an instruction for a user to input a key pattern during face authentication;
allowing an image capturing unit to capture a face of a user and/or a movement of a portion of the face of the user during a portion of or the entire time from when the presentation pattern display unit displays the instruction to when the key input is completed; and
determining whether the captured face image is of a living body,
wherein the presentation pattern display unit displays an instruction to see the image capturing unit while the user alternately views the presentation pattern display unit and the key input unit.
7. The face authenticating method according to claim 6 , wherein the presentation pattern display unit is separated from the key input unit in the vertical direction.
8. The face authenticating method according to claim 6 , wherein the presentation pattern display unit displays a portion of the instruction, detects an input timing to the key input unit, and displays the other portion of the instruction after the input is confirmed.
9. The face authenticating method according to claim 6 , wherein the presentation pattern display unit displays a keypad including random numbers arranged thereon to allow the user to input keys corresponding to the arrangement using the key input unit.
10. The face authenticating method according to claim 6 , further comprising:
determining whether, after a rational time has elapsed after the presentation pattern display unit displays a predetermined instruction, a key input corresponding to the instruction is performed on the key input unit.
11. A non-transitory computer-readable medium storing a program for allowing a computer to implement the function according to claim 1 .
12. A face authenticating apparatus according to claim 1 , further comprising:
a determining unit to determine whether the captured face is a face of a living body, by comparing a plurality of frames of the captured face.
13. A face authenticating method according to claim 6 , further comprising:
determining whether the captured face is a face of a living body, by comparing a plurality of frames of the captured face.
14. A face authenticating apparatus comprising:
a keypad;
a display device that is provided at a different position from the keypad, wherein the display device is adapted to display an instruction for a user to input a key pattern during face authentication;
a camera adapted to capture a face of a user and/or a movement of a portion of the face of the user during a portion of or the entire time from when the display device displays the instruction to when the key input is completed; and
a processor adapted to determine whether the captured face image is of a living body,
wherein the display device displays an instruction to see the camera while the user alternately views the display device and the keypad.
15. The face authenticating apparatus according to claim 14 , wherein the display device is separated from the keypad in a vertical direction.
16. The face authenticating apparatus according to claim 14 , wherein the display device displays a portion of the instruction, detects an input timing to the keypad, and displays another portion of the instruction after the input is confirmed.
17. The face authenticating apparatus according to claim 14 , wherein the display device displays random numbers to allow the user to input keys corresponding to the arrangement using the keypad.
