Abstract

A document management server includes a document information managing unit, a location information acquisition unit, and an information transmitting unit. The document information managing unit controls public document information and non-public document information. The public document information is freely browsable. The non-public document information is browsable inside a permission area. The location information acquisition unit acquires location information of a mobile terminal to browse the non-public document information. The information transmitting unit determines whether or not the mobile terminal is inside the permission area based on the acquired location information and transmits the non-public document information to the mobile terminal while the mobile terminal is determined to be in the permission area.

Claims

1. A document management server, comprising:

a document information managing unit that controls public document information and non-public document information, the public document information being freely browsable, the non-public document information being browsable inside a permission area;

a location information acquisition unit that acquires location information of a mobile terminal to browse the non-public document information; and

an information transmitting unit that determines whether or not the mobile terminal is inside the permission area based on the acquired location information and transmit the non-public document information to the mobile terminal while the mobile terminal is determined to be in the permission area.

2. A document browsing system, comprising:

a document management server; and

a mobile terminal,

wherein the document management server includes;

a document information managing unit that controls public document information and non-public document information, the public document information being freely browsable, the non-public document information being browsable inside a permission area;

a location information acquisition unit that acquires location information of a mobile terminal to browse the non-public document information; and

an information transmitting unit that determines whether or not the mobile terminal is inside the permission area based on the acquired location information and transmit the non-public document information to the mobile terminal while the mobile terminal is determined to be in the permission area,

wherein the mobile terminal includes;

a browse requesting unit that transmits the location information of the mobile terminal to request browsing of the non-public document information; and

a display processing unit that receives the non-public document information from document management server and display the received non-public document information on a screen.

3. The document browsing system according to claim 2,

wherein the mobile terminal includes an identification information receiving unit that accepts input of document identification information that identifies the non-public document information,

the browse requesting unit is that transmits the document identification information accepted along with the location information when requesting the browsing, and

the information transmitting unit is that transmits the non-public document information that corresponds to the document identification information to the mobile terminal situated in the permission area.

4. The document browsing system according to claim 3,

wherein the document management server includes a document information managing unit that:

respectively controls a public part and a non-public part in a same document as the public document information and the non-public document information, and control the document identification information of the non-public document information along with the public document information in the same document to be printed out on a paper sheet.

5. The document browsing system according to claim 4,

wherein the identification information receiving unit images the document identification information printed out on the paper sheet to accept the input of the document identification information, and

the browse requesting unit requests the browsing in response to the acceptance of the input of the document identification information.

6. The document browsing system according to claim 2,

wherein the mobile terminal includes a terminal identification information managing unit that controls terminal identification information to identify the mobile terminal,

the browse requesting unit transmits the terminal identification information to the document management server when requesting the browsing,

the document information managing unit manages the mobile terminal permitted to browse the non-public document information, and

the information transmitting unit transmits the non-public document information to the mobile terminal when the mobile terminal situated in the permission area is permitted to browse the non-public document information based on the terminal identification information received from the mobile terminal.

7. The document browsing system according to claim 2,

wherein the document information managing unit manages area information that identify a range of the permission area,

the information transmitting unit transmits the area information along with the non-public document information to the mobile terminal, and

the mobile terminal includes an area monitoring unit that monitors whether or not the mobile terminal is inside the permission area based on the area information received from the document management server and the location information of the mobile terminal, and

the display processing unit halts the display of the non-public document information while the mobile terminal is situated outside the permission area by the monitoring.

8. The document browsing system according to claim 7,

wherein the display processing unit deletes the non-public document information received from the document management server while halting the display on the screen.

9. A non-transitory computer-readable recording medium storing a document management server program, the document management server program causing a computer to function as:

a document information managing unit that controls public document information and non-public document information, the public document information being freely browsable, the non-public document information being browsable inside a permission area;

a location information acquisition unit that acquires location information of a mobile terminal to browse the non-public document information; and

an information transmitting unit that determines whether or not the mobile terminal is inside the permission area based on the acquired location information and transmit the non-public document information to the mobile terminal while the mobile terminal is determined to be in the permission area.

10. The non-transitory computer-readable recording medium according to claim 9, the document management server program causing the computer to function as:

a browse requesting unit that causes the mobile terminal to transmit the location information of the mobile terminal to request browsing of the non-public document information; and

a display processing unit that causes the mobile terminal to receive the non-public document information transmitted by the information transmitting unit and display the non-public document information on a screen of the mobile terminal.
