Abstract

An MFP sets an access condition for an external device with respect to a cloud box. The access condition is transmitted from the MFP to a relay device, and is registered in a memory of the relay device. When the relay device receives an access request made by the external device with respect to the MFP serving as an internal device, the relay device determines whether to permit or deny access to the MFP by comparing the access request with the access condition. When the access is permitted, the access request is transferred from the relay device to the MFP, whereas when the access is denied, the relay device notifies the external device of it.

Claims

1. An image processing system comprising:

an image formation apparatus comprising a first processor;

a relay device configured to relay communication between said image formation apparatus and an external device external to the image processing system, the relay device comprising a second processor;

wherein the first processor provided in the image formation apparatus is configured to set an access condition for said external device with respect to a memory region accessible by other devices, included in said image formation apparatus wherein the memory region is prepared in advance for access from the external device and is distinguishable from an other memory region, and wherein the first processor is configured to transmit said access condition to the relay device;

wherein the second processor provided in the relay device is configured to register said access condition in a memory;

wherein the second processor is configured to receive an access request, said access request being made by said external device with respect to an internal device, which is a device included in the image processing system;

wherein the second processor is configured to determine whether to permit or deny access to said image formation apparatus by comparing said access request with said access condition when said access request is a request for access to said image formation apparatus;

wherein the second processor is configured to transfer said access request to said image formation apparatus when said second processor determines to permit the access from said external device; and

wherein the second processor is configured to notify said external device that the access has been denied when said second processor determines to deny the access from said external device.

2. A relay device for relaying communication between at least one image formation apparatus included in a system to which said relay device belongs and an external device not included in said system, the image formation apparatus comprising a memory region accessible by other devices, the relay device comprising:

a processor;

a memory;

wherein the processor provided in the relay device is configured to register at least one first access condition in the memory, said first access condition being received from the image formation apparatus, said first access condition being used for access to the memory region of said image formation apparatus, wherein the memory region is prepared in advance for access from the external device and is distinguishable from an other memory region, wherein the other memory region includes a memory region accessible by an internal device in said system;

wherein the processor is configured to receive an access request made by said external device with respect to said image formation apparatus;

wherein the processor is configured to determine whether to permit or deny access to said image formation apparatus by comparing said access request with said first access condition when said access request is a request for access to said image formation apparatus;

wherein the processor is configured to transfer said access request to said image formation apparatus when said processor determines to permit the access from said external device; and

wherein the processor is configured to notify said external device that the access has been denied when said processor determines to deny the access from said external device.

3. The relay device according to claim 2, wherein the processor is configured to register at least one second access condition in said memory, said second access condition being received from the image formation apparatus, said second access condition being used for access to a document stored in said memory region, wherein

when said second access condition with respect to the document designated by said access request is registered in said memory, said processor is configured to permit or deny the access to said image formation apparatus by comparing said access request with said second access condition.

4. The relay device according to claim 3, wherein said processor is configured to register said second access condition in said memory when each second access condition is included in said first access condition.

5. The relay device according to claim 2,

wherein the processor is configured to register at least one second access condition in said memory, said second access condition being received from an image formation apparatus, said second access condition being used for access to a document stored in said memory region, wherein

when said processor determines that said first access condition is satisfied by comparing said access request, which is a request for access to said image formation apparatus, with said first access condition, said processor is further configured to determine whether to permit or deny the access from said external device by comparing said access request with said second access condition.

6. The relay device according to claim 5, wherein

said processor is configured to register said second access condition in said memory when each second access condition is included in said first access condition.

7. An image formation apparatus comprising the relay device recited in claim 2.

8. A non-transitory computer-readable storage medium storing a program causing a computer, which serves as a relay device, to perform an access management process, said relay device relaying communication between at least one internal device included in a system to which the relay device belongs and an external device not included in said system,

said program causing a processor provided in said computer serving as a relay device to perform:

registering at least one first access condition in a memory, said first access condition being received from an image formation apparatus serving as said internal device, said first access condition being used for access to a memory region accessible by other devices of said image formation apparatus, wherein the memory region is prepared in advance for access from the external device and is distinguishable from an other memory region, wherein the other memory region includes a memory region accessible by an internal device in said system;

receiving an access request made by said external device with respect to said internal device;

determining whether to permit or deny access to said image formation apparatus by comparing said access request with said first access condition when said access request is a request for access to said image formation apparatus; and

transferring said access request to said image formation apparatus when it is determined to permit the access from said external device, and notifying said external device that the access has been denied when it is determined to deny the access from said external device.
