Description

  The present invention relates to an information processing apparatus such as a personal computer or a workstation, and an application program that executes processing according to an input such as document management, document creation, and drafting incorporated in the information processing apparatus. The present invention relates to an application program that may be operated for a long time and the information processing apparatus in which the application program is incorporated.

  Currently, in information processing apparatuses such as personal computers, workstations, and servers, software that displays full-color black or moving images to prevent screen burn-in caused by continuing to display the same image when there is no input for a predetermined period. A so-called screen saver is used. The screen saver is terminated when any input is made, and the original image is displayed.

However, when the information processing device is activated and the user is in the middle of the situation and the information processing device cannot be managed or monitored, another person operates the input device such as a keyboard or a mouse to activate it. Any application program can be started and operated simply by ending the screen saver. Therefore, there is no authority to use, and an operation of a third person who cannot (or should not) originally use is possible, which may lead to information leakage, destruction of the information processing apparatus (data disappearance, etc.) and the like.
In order to deal with such problems, a password (authentication information) is set in the screen saver software, and before the screen saver is terminated and the original image is displayed, authentication is performed by prompting for the password. If it is not received, it is possible to prohibit the display of the original image and the operation of the software.

(Problems of conventional technology)
However, when authenticating with a password at the end of the screen saver, if the password of the screen saver is known, there is a problem that all software installed in the information processing apparatus can be freely used.
As a countermeasure, a password authentication is performed when starting each software (application program) separately from the screen saver, and attempts have been made to prevent the use of arbitrary software after the screen saver is released.
However, if the user is in the middle while the application program is activated, the display image of the activated application program can be referred to or operated by releasing the screen saver. Therefore, there is a problem that confidential information or the like is leaked to the outside when an arbitrary operation of a third party or confidential information or personal information is displayed on the display image.
In particular, in a server or the like, service software that provides various services through a network may be operated all day, and it is necessary to avoid making such software arbitrarily operable by a third party.

In view of the above circumstances, the present invention has the following description (O01) as a technical problem.

(Operation of Example 1)
In the client personal computer PC as the information processing apparatus of the first embodiment having the above-described configuration, when the document management software AP2 as the application program is activated and no input is continuously made for the input prohibition determination time ta. Is set to an input prohibited state (operation prohibited state) (see ST8 in FIG. 6). If the user is not authenticated by the password and confirmed to be a user of the document management software, the operation cannot be performed. Therefore, even if the user is away from the client personal computer PC with the document management software AP2 activated, if the user is not authenticated, the input prohibited state (see ST8) does not change to the input ready state (see ST12). It is possible to prevent the document management software AP2 from being operated. As a result, it is possible to prevent data from being falsified or lost due to the use of document management software, and security can be improved.

Further, in the document management software AP2 of the first embodiment, when the input prohibited state (operation prohibited state) is entered, the display column 12 and the like of the main image 11 are updated to the unviewable image 31, so even if the screen saver is released, There is no fear of browsing the content displayed on the main image. Therefore, the risk of information leakage can be reduced.
Furthermore, since the document management software AP2 of the first embodiment is also authenticated at the time of activation, even if the document management software AP2 is activated after the screen saver is released by a third party, the document management software AP2 is not activated unless authenticated. The possibility of being operated freely by a third party or browsing the contents can be reduced.
In the document management software AP2 of the first embodiment, since the user can set the operation prohibition determination time ta, it is possible to make an appropriate setting according to the use environment.

Further, in the document management software AP2 of the first embodiment, when the screen saver AP1 is activated, the input prohibited state is entered even if the operation prohibition determination time ta has not elapsed. Therefore, the screen is displayed on the main image 11 when the screen saver AP1 is released. You can prevent browsing of the contents.
Further, in the document management software AP2 of the first embodiment, regardless of the screen saver AP1, when the operation prohibition determination time ta elapses, the input prohibition state is entered. Therefore, for example, another operation (drawing, document creation, etc.) is performed in a state where the document management software AP2 is minimized, and then the user leaves the client personal computer PC and the third party is in a state where the screen saver AP1 is not activated. Even if the document management software AP2 is returned to the original size, the non-viewable image 31 is displayed and the input operation cannot be performed. Therefore, it is possible to prevent a third party from freely operating or leaking information.

  Next, the information processing apparatus according to the second embodiment of the present invention will be described. In the description of the second embodiment, components corresponding to the components of the first embodiment are denoted by the same reference numerals, and details thereof are described.
