Patent ID: 7605933

Claim:
A method for determining whether a configuration state of a document-processing device has changed, comprising: receiving, from the document-processing device, first state data that describes a first configuration state of the document-processing device; in response to receiving a request, from a requestor, to verify that the configuration state of the document-processing device has not changed since the first configuration state, sending a request for second state data to the document-processing device; receiving, from the document-processing device, the second state data that describes a second configuration state of the document-processing device, wherein the second state data is received subsequently to the receipt of the first state data; comparing the first state data with the second state data to determine if the first state data and the second state data identify the same configuration state of the document-processing device; and transmitting, to the requestor, a message indicating whether the configuration state of the document-processing device has changed since the first configuration state based on the comparison of the first state data with the second state data.
