1. A non-transitory computer-readable medium storing an information control program configured to carry out instructions, comprising:
instructions for adding a predetermined modification to a transmitted/received information which is transmitted and received between an operating system and an application program, the application program being executable on the operating system and capable of generating a data file and saving the data file to an arbitrary information storage area as a storage destination,
wherein the instructions for adding the predetermined modification comprise:
save restriction instructions for (i) permitting saving of the data file only when the data file is encrypted using a predetermined encryption key,
storage destination restriction instructions for permitting the saving of the data file only when a predetermined area in the information storage area is designated as the storage destination of the data file,
decrypting instructions for decrypting the data file stored in the predetermined area using the predetermined encryption key,
image replication restricting instructions for (i) restricting replication of image information of the data file displayed on a display device based on the information of the data file, (ii) disabling input of a signal for executing screen capture, (iii) protecting the image information from acquisition by photography of a display screen of the display device, and (iv) terminating a screen saver and displaying the image information when a user terminates an application having the screen capture function, and
replication restricting instructions for (i) replicating part of information of the data file, (ii) permitting the replicated part of the information of the data file to be saved only in an encrypted state readable by the application program, and (iii) providing one or more alerts to the user when an attempt to paste the replicated part of the information of the data file to a document being edited in a program other than the application program,
wherein the one or more alerts inform the user that the replicated part of the information cannot be passed to the document,
wherein the predetermined encryption key is stored in the predetermined area in the information storage area, and
wherein the predetermined encryption key is automatically generated by the information control program.
