Next, a description will be given of a first operation example mainly composed of processing requiring password authentication with reference to the flowchart shown in FIG.
When the main control unit 24 receives a process requiring password authentication (step S1), the main control unit 24 displays a password input screen as shown in FIG. In FIG. 4, 31 is a guidance sentence for guiding the input of a password, 32 is a password input display section for displaying a symbol indicating that the password has been input, and 33 is a secret information input section for inputting a password which is secret information. The password input part (such as numeric keypad) is usually displayed at the center of the screen.

  Next, the main control unit 24 captures an image acquired from the camera 8, and detects a human face image from the captured image (step S2). Here, the detection method of the face image is, for example, literature (Fukui, Yamaguchi. “Face feature point extraction by combination of shape extraction and pattern matching”, Science theory, (D), vol. J80-DH, No. .8, pp. 2170-2177, 1997) or a face position extraction method described in Japanese Patent Application Laid-Open No. 2004-185611, etc., to detect a face image with high accuracy. Is feasible.

  Next, the main control unit 24 determines whether there is another person near the user, for example, behind the user based on the detection result of the face image (step S3). Here, for example, when there are two or more face images detected in step S2, it is determined that there is another person behind the user. This is possible. If the result of determination in step S3 is that there is another person behind the user, the main control unit 24 checks the positional relationship between the user and the person behind (step S4). The method of examining the positional relationship is, for example, using a person who exists in the center of the image acquired by the camera 8 as a user, and a person in the face image detected at the largest size among other persons as a person behind. There is a method for determining the positional relationship with the user, which is considered right and left. Next, the main control unit 24 moves and displays the password input unit 33 to a position where it is difficult to see from the position of the person behind (step S5). As an example of displaying in a position that is difficult to see from the position of the person behind, for example, as shown in FIG. 5, when another person M2 behind is present on the right side of the user M1, the display device 11 is shown in FIG. The password input unit 33 is moved and displayed on the left side of the screen.

Next, the main control unit 24 performs processing after password authentication, that is, password input processing by operating the password input unit 33, authentication processing using the input password, and transaction processing such as a withdrawal transaction based on the authentication result. It carries out sequentially (step S6).
As a result of the determination in step S3, when there is no other person behind the user, the main control unit 24 displays the password input unit 33 at the normal position (center) of the screen of the display device 11 (step S7). ). That is, the display position of the password input unit 33 is not changed, and remains at the position shown in FIG.

  Next, the main control unit 24 sequentially performs processing after password authentication, that is, input of a password by operating the password input unit 33, authentication processing using the input password, and transaction processing such as a withdrawal transaction based on the authentication result. Implement (step S6).

Further, since the arrangement of numbers in the password input unit 33 is not changed, the arrangement becomes familiar to the user, is easy to input, and is excellent in convenience.

Next, a second operation example mainly including processing requiring password authentication will be described with reference to the flowchart shown in FIG.
When the main control unit 24 receives a process requiring password authentication (step S11), the main control unit 24 displays a password input screen as shown in FIG. Next, the main control unit 24 captures an image acquired from the camera 8, and detects a human face image from the captured image (step S12).

  Next, the main control unit 24 determines whether there is another person in the vicinity of the user, for example, behind the user based on the detection result of the face image (step S13). As a result of the determination, if there is another person behind the user, the main control unit 24 causes the display device 11 to display another person behind the password input unit 33, for example, as shown in FIG. The guide information (warning text) 34 indicating that there is a message is displayed (step S14).

Next, the main control unit 24 performs processing after password authentication, that is, password input processing by operating the password input unit 33, authentication processing using the input password, and transaction processing such as a withdrawal transaction based on the authentication result. It implements sequentially (step S15).
If the result of determination in step S13 is that there is no other person behind the user, the main control unit 24 jumps to step S14 and proceeds to step S15.

  As described above, when there is another person behind the user who operates the password input unit 33, a warning is displayed near the password input unit 33, thereby prompting the user to pay attention when entering the password. It is possible to prevent peeping in password input operations.

Next, a third operation example based on a process requiring password authentication will be described with reference to a flowchart shown in FIG.
When the main control unit 24 receives a process requiring password authentication (step S21), the main control unit 24 displays a password input screen as shown in FIG. Next, the main control unit 24 captures an image acquired from the camera 8, and detects a human face image from the captured image (step S22).

  Next, the main control unit 24 determines whether there is another person near the user, for example, behind the user based on the detection result of the face image (step S23). As a result of the determination, if there is another person behind the user, the main control unit 24 moves to the display device 11, for example, near the password input unit 33 as shown in FIG. The image 35 around the user acquired in step S24 is displayed (step S24).

Next, the main control unit 24 performs processing after password authentication, that is, password input processing by operating the password input unit 33, authentication processing using the input password, and transaction processing such as a withdrawal transaction based on the authentication result. It implements sequentially (step S25).
If the result of determination in step S23 is that there is no other person behind the user, the main control unit 24 jumps to step S24 and proceeds to step S25.

  As described above, when there is another person behind the user who operates the password input unit 33, an image around the user at this time is displayed near the password input unit 33, so Compared to the case of looking at the mirror attached to the camera, the camera 8 displayed near the password input unit 33 can be used to confirm the back, so that attention is not distracted from the hand, and peeping of the password input operation is prevented. be able to.
