INFORMATION PROCESSING DEVICE AND NON-TRANSITORY COMPUTER READABLE MEDIUM
An information processing device includes a display and a changing unit. The display displays a document that an authorized user having an authorization is able to access. The changing unit changes a presentation mode of the document in accordance with a probability that an unauthorized user is able to view or read content of the document. The probability is calculated from a situation where the authorized user is displaying the document.
1 . An information processing device comprising:
a display that displays a document that an authorized user having an authorization is able to access; and
a changing unit that changes a presentation mode of the document in accordance with a probability that an unauthorized user is able to view or read content of the document, the probability being calculated from a situation where the authorized user is displaying the document.
2 . The information processing device according to claim 1 , wherein the changing unit changes the presentation mode of the document in accordance with a time for which the document is being displayed.
3 . The information processing device according to claim 2 , wherein the time for which the document is being displayed is a time for which no operation is performed on the displayed document.
4 . The information processing device according to claim 1 , wherein, if the document is set to be unavailable for access and is then displayed again in a state in which the document is available for access, the changing unit changes the presentation mode of the document to a presentation mode in which the document has been displayed before the document is set to be unavailable for access.
5 . The information processing device according to claim 4 , wherein, if a time from when the document is set to be unavailable for access until when the document is displayed again is greater than or equal to a threshold or exceeds the threshold, the changing unit changes the presentation mode of the document to a presentation mode in which the document has been displayed for the first time rather than to a presentation mode in which the document has been displayed immediately before the document is set to be unavailable for access.
6 . The information processing device according to claim 4 , wherein the changing unit changes the presentation mode of the document by comparing a time from when the document is set to be unavailable for access until when the document is displayed again with a threshold determined by using a screen lock start time.
7 . The information processing device according to claim 6 , wherein the changing unit sets the threshold to be a time longer than the screen lock start time, and changes the presentation mode of the document if the time for which the document has been unavailable is smaller than or smaller than or equal to the threshold.
8 . A non-transitory computer readable medium storing a program causing a computer to execute a process, the process comprising:
displaying a document that an authorized user having an authorization is able to access; and
changing a presentation mode of the document in accordance with a probability that an unauthorized user is able to view or read content of the document, the probability being calculated from a situation where the authorized user is displaying the document.
9 . An information processing device comprising:
display means for displaying a document that an authorized user having an authorization is able to access; and
changing means for changing a presentation mode of the document in accordance with a probability that an unauthorized user is able to view or read content of the document, the probability being calculated from a situation where the authorized user is displaying the document.
