Abstract

There is provided an image forming apparatus that eliminates the need for separately preparing an encrypted file for each user. To achieve this, the image forming apparatus performs control of browsing of a browsing file that is browsed at a terminal. The document acquisition portion of the image forming apparatus acquires document data. The document encryption portion encrypts the document data with a public key as the browsing file. The position information setting portion sets position information to permit browsing of the browsing file encrypted by the document encryption portion in a viewer for causing the browsing file to be browsed at the terminal. In the case where it has been determined that the position information coincides with a current position, a browsing execution portion at the terminal uses a secret key to decrypt the browsing file for causing it to be browsed.

Claims

1. An image forming apparatus, performing control of browsing of a file by a terminal, comprising:

an encryption portion configured to encrypting said file with a public key, and

a browsing permitting position information setting portion configured to setting position information, which is to permit browsing of said file encrypted by said encryption portion, in a viewer for causing said file to be browsed at said terminal.

2. The image forming apparatus according to claim 1, further comprising:

a position information storage unit configured to storing said viewer,

a secret key setting portion configured to setting a secret key to decrypt said file in said viewer stored in said position information storage unit, and

a transmission unit configured to transmitting said viewer set with said secret key by said secret key setting portion, and said file to said terminal.

3. A terminal for browsing a file encrypted by an image forming apparatus, comprising:

a position information storage unit configured to storing position information to permit browsing of said file,

a position information determination portion configured to determining whether the position information stored in said position information storage unit coincides with a current position, and

a browsing execution portion, upon said position information determination portion having determined that the position information included in a viewer coincides with a current position, using the viewer stored in said position information storage unit to decrypt said file for causing it to be browsed.

4. A file browsing control system, performing control of browsing of a file with an image forming apparatus and a terminal,

said image forming apparatus comprising:

an encryption portion configured to encrypting said file with a public key, and

a browsing permitting position information setting portion configured to setting position information, which is to permit browsing of said file encrypted by said encryption portion, in a viewer for causing said file to be browsed at said terminal,

said terminal comprising;

a position information storage unit configured to storing position information set by said browsing permitting position information setting portion in said viewer,

a position information determination portion configured to determining whether the position information included in a viewer stored in said position information storage unit coincides with a current position,

a browsing execution portion, upon said position information determination portion having determined that the position information included in a viewer coincides with a current position, using the viewer stored in said information storage unit to decrypt said file for causing it to be browsed.

5. An image forming method, being executed by an image forming apparatus, performing control of browsing of a file with a terminal,

encrypting said file with a public key, and

setting position information, which is to permit browsing of said file encrypted, in a viewer for causing said file to be browsed at said terminal.

6. A non-transitory computer-readable recording medium storing a program, causing an image forming apparatus performing control of browsing of a file with a terminal, to functions as:

an encryption portion configured to encrypting said file with a public key, and

a browsing permitting position information setting portion configured to setting position information, which is to permit browsing of said file encrypted by said encryption portion, in a viewer for causing said file to be browsed at said terminal.
