Description

The present disclosure relates to an authentication device, an authentication method and an authentication program.

Many users of terminals equipped with a touch panel, such as smartphones and tablet terminals, use the screen lock function to prevent a third party from operating their own terminal. For example, pattern authentication is an example of a screen lock function in a smartphone. "Pattern authentication" is an image for deauthentication in which nine panels are arranged in a 3x3 grid pattern displayed on a smartphone when the screen lock function is released, and the user registers the panel in advance. , It is an authentication method that is canceled by tracing in the order registered in advance.

However, in this "pattern authentication" method, the line of the authentication pattern (trajectory traced by the user's finger) is drawn large on the screen of the terminal at the time of authentication, so that it is easy for a third party to peep. Moreover, the pattern can be stored relatively easily. That is, the third party can easily clear the authentication of the user's terminal by peeping into the user's terminal and memorizing the pattern at the time of authentication. Therefore, techniques related to such risks have been studied (for example, Patent Document 1).

In Patent Document 1, a matrix array of N objects is displayed as an image for inputting authentication information, an object selected by the user is replaced with an adjacent object, and the displayed image matches the authentication deauthentication pattern. Successful authentication is disclosed.

In the left figure of FIG. 3, in the authentication image, the panel arranged near the "authentication" button 23 is the panel in the fourth row, and the top and leftmost panel is arranged in the first row and the first column. In the case of a panel, it is a diagram showing a state before the user taps the panel in the third row and the third column. The right figure of FIG. 3 is a diagram showing a state after the user taps the panel in the third row and the third column in the authentication image.

First, the authentication image 21 will be described with reference to the left figure of FIG. The authentication image 21 is an image displayed on the touch panel display of the authentication device 10 and is an image displayed when the authentication device 10 is unlocked. The authentication image 21 includes a panel area 22 and an “authentication” button 23.

The panel area 22 is an area in which 16 panels are arranged in a 4 × 4 grid pattern.
The "authentication" button 23 is a button pressed by the user when unlocking the authentication device 10.

When the user unlocks the authentication device 10, the user taps the panel arranged in the panel area 22 to change the color displayed on the upper, lower, left, and right panels of the tapped panel. When the colors displayed on the plurality of panels arranged in the panel area 22 satisfy the predetermined conditions and the user presses the "authentication" button 23, the lock of the authentication device 10 is released.

On the other hand, if the user presses the "authentication" button 23 while the colors displayed on the plurality of panels arranged in the panel area 22 do not satisfy the predetermined conditions, the lock of the authentication device 10 is not released. In this case, for example, a message indicating that the authentication has failed, such as "Authentication failed", is displayed, and all the panels are changed to red.

Next, the panel control of the panel control unit 12 will be described. As shown in the left figure of FIG. 3, it is assumed that the user taps the panel in the third row and the third column, and white is displayed on the upper, lower, left, and right panels of the panel in the third row and the third column. Then, the panel control unit 12 changes the colors of the upper, lower, left, and right panels of the tapped panel according to a predetermined change pattern.

When the user presses the "authentication" button 23 in this state, the unlocking unit 13 unlocks the authentication device 10 because the colors displayed on the plurality of panels satisfy the unlocking condition.

Here, the user taps one panel, while the color is changed to a plurality of panels. Therefore, for example, even if a third party peeks at the situation at the time of unlocking, the third party can easily grasp which panel color affects the unlocking of the authentication device 10. I can't. Further, for example, it is assumed that the user unlocks the authentication device 10 by tapping a panel that is not related to the panel specified as a condition for unlocking the authentication device 10. In this case, the third party presumes that the panel tapped by the user affects the unlocking of the authentication device 10. However, since the panel tapped by the user is a panel that does not affect the unlocking of the authentication device 10, a third party can easily grasp which panel color affects the unlocking of the authentication device 10. I can't.

Returning to FIG. 2, the registration unit 14 will be described.
