If dummy (information protection) is passcode authentication, set the passcode for dummy authentication. If the dummy (information protection) is pattern authentication, set the dummy authentication pattern. Next, select a dummy (fake) post-login screen (image) to be displayed on the user terminal. Note that if it has been set in advance in an app, etc., the selection of the dummy post-login screen can be omitted. Next, select an authentication method. For passcode authentication, set the passcode for real authentication, and for pattern authentication, set the pattern for real authentication. Note that in selecting the authentication method, real authentication cannot be set as dummy authentication.

FIG. 10 is a flowchart showing the implementation (operation) of information protection in this embodiment. First, the user taps the login screen of the terminal used by the user. At that time, the user determines whether to unlock (authenticate) the user's will. If you do not unlock (authenticate) your own will ("No"), enter a dummy passcode or pattern and perform biometric authentication, and the specified dummy post-login screen (fake post-login image) will be displayed. Ru. On the other hand, when unlocking (authenticating) the user's own will (“Yes”), the user further determines whether or not someone is looking into the terminal being used by the user. If you are being watched ("yes"), enter a dummy passcode or pattern and perform biometric authentication, and a prescribed dummy post-login screen (fake post-login image) will be displayed. If you are not being watched ("No"), enter the real passcode or pattern mentioned above and perform biometric authentication, and a prescribed correct post-login screen (genuine post-login image) will be displayed.

FIG. 11 shows two authentication screens in this embodiment. The authentication screen on the left side of the figure is an example of a screen when the dummy lock is passcode authentication and the real lock is pattern authentication. On the authentication screen, number buttons from "1" to "9" are displayed so that six numbers can be entered. Each number button is a point (position) button for pattern authentication, and normal authentication (real In the case of (unlocked), if you enter the normal (real) pattern you have set, a genuine login image will be displayed. The authentication screen on the right side of the figure is an example of a screen when the dummy lock is pattern authentication and the real lock is passcode authentication. On the authentication screen, an instruction text "Please draw a release pattern" is displayed, and nine point (position) buttons for pattern authentication are displayed. Each button functions as a numeric button. In the case of normal authentication (real lock release), if you enter the normal (real) passcode (sequence of numbers) that you have set, an image will be displayed after authentic login. As in this example, by separating normal authentication (real authentication) and information protection authentication (dummy authentication) into passcode authentication and pattern authentication, normal authentication (real authentication) can be performed even if the user terminal is being viewed. Authentication method is protected.
