Abstract

An information processing device includes a hardware processor. The hardware processor modifies a name of a folder or a file into a different character string with respect to the original character string describing the folder or file and output the modified character string to the terminal device when a request for displaying the name of the folder or the file stored in a memory is received from a user of the terminal device who is not granted with an access right for accessing the folder or the file stored in the memory.

First claim

What is claimed is:

1 . An information processing device comprising:
a hardware processor configured to:
in a case where a request for displaying a name of a folder or a file stored in a memory is received from a terminal device, modify a name of a folder or a file to which a user of the terminal device is not granted an access right into a different character string and output the modified character string to the terminal device,
wherein the hardware processor is configured to modify the name of the folder or the file to which the user of the terminal device is not granted the access right into a character string containing an expression indicating that the access right is not granted,
wherein the hardware processor is further configured to modify the name of the folder or the file to which the user of the terminal device is not granted the access right into a meaningless character string, and the meaningless character string is a character string presenting information in sequence of characters that does not convey any recognizable or understandable information.

2 . The information processing device according to claim 1 , wherein the hardware processor is configured to modify the name of the folder or the file to which the user of the terminal device is not granted the access right into a character string containing a specific character string satisfying a predetermined condition.

3 . The information processing device according to claim 2 , wherein the hardware processor is configured to modify the name of the folder or the file to which the user of the terminal device is not granted the access right into a character string containing a character for sorting at beginning of the character string.

4 . The information processing device according to claim 3 , wherein the hardware processor is configured to determine the character for sorting, based on a name of a folder or a file to which the user of the terminal device is granted the access right.

5 . The information processing device according to claim 2 , wherein the hardware processor is configured to modify the name of the folder or the file to which the user of the terminal device is not granted the access right into a character string containing a first one or more characters of the name of the folder or the file.

6 . The information processing device according to claim 2 , wherein the hardware processor is configured to modify the name of the folder or the file to which the user of the terminal device is not granted the access right into a character string containing a predetermined extension.

7 . The information processing device according to claim 1 , wherein the hardware processor is configured to modify, in accordance with a predetermined modification rule, the name of the folder or the file to which the user of the terminal device is not granted the access right.

8 . The information processing device according to claim 7 , wherein the hardware processor is configured to, in a case where the access right to access the folder or the file whose name has been modified is granted the user of the terminal device, restore a name in accordance with the modification rule and output the restored name to the terminal device.

9 . The information processing device according to claim 1 , wherein the hardware processor is configured to modify the name of the folder or the file in a different manner in accordance with a type of access right to access the folder or the file that the user of the terminal device is not granted.

10 . An information processing method comprising:
in a case where a request for displaying a name of a folder or a file stored in a memory is received from a terminal device, modifying a name of a folder or a file to which a user of the terminal device is not granted an access right into a different character string and output the modified character string to the terminal device; modifying the name of the folder or the file to which the user of the terminal device is not granted the access right into a character string containing an expression indicating that the access right is not granted; and modifying the name of the folder or the file to which the user of the terminal device is not granted the access right into a meaningless character string, and the meaningless character string is a character string presenting information in sequence of characters that does not convey any recognizable or understandable information.

11 . A non-transitory computer readable medium storing a program causing a computer to execute a process, the process comprising:
in a case where a request for displaying a name of a folder or a file stored in a memory is received from a terminal device, modifying a name of a folder or a file to which a user of the terminal device is not granted an access right into a different character string and output the modified character string to the terminal device; modifying the name of the folder or the file to which the user of the terminal device is not granted the access right into a character string containing an expression indicating that the access right is not granted; and modifying the name of the folder or the file to which the user of the terminal device is not granted the access right into a meaningless character string, and the meaningless character string is a character string presenting information in sequence of characters that does not convey any recognizable or understandable information.
