METHOD AND SYSTEM FOR MEASUREMENT OF RESOURCE METERS
First Claim
1. A method for measurement of resource meters, the method comprising:
- (a) receiving, from each of multiple site aggregation units;
(i) site aggregation data comprising aggregated resource measurements from at least one of the resource meters, wherein the site aggregation data from all the site aggregation units comprise aggregated resource measurements from all of the resource meters; and
(ii) a site aggregation digest that substantially uniquely identifies the resource measurements;
(b) storing the site aggregation digests received from the multiple site aggregation units;
(c) aggregating the site aggregation data received from the site aggregation units into central aggregation data; and
(d) transmitting the central aggregation data to a resource distributor.

Abstract
The present disclosure is directed at methods, systems, and techniques for measurements and, optionally, auditing of resource meters such as electricity meters. Each of multiple site aggregation units receive measurements from resource meters. Each of the site aggregation units generate a site aggregation digest that substantially uniquely identifies the resource measurements, stores these digests, and aggregates the resource measurements into site aggregation data that is sent to a central aggregation unit. The central aggregation unit generates a central aggregation digest that substantially uniquely identifies the site aggregation data, stores this digest, and aggregates the site aggregation data into central aggregation data that is sent to a resource provider with the central aggregation digest. When auditing is to be performed, the site and central aggregation digests can be used to verify the authenticity of the resource measurements and the site aggregation data, respectively.

11. The method of claim 11 wherein each of the site aggregation units stores the resource measurements used to generate the site aggregation data and digests, and further comprising auditing the resource measurements transmitted by any one of the site aggregation units by, at the site aggregation unit being audited (“
- audited site aggregation unit”
);(a) regenerating the site aggregation digest from the resource measurements stored by the audited site aggregation unit; (b) comparing the site aggregation digest that is regenerated to the site aggregation digest received from the audited site aggregation unit and that has been stored by the central aggregation unit; and (c) determining that the resource measurements are authentic when the site aggregation digest that is regenerated is identical to the site aggregation digest received from the audited site aggregation unit and that has been stored.

12. The method of claim 12 further comprising auditing the resource meters that send the resource measurements to any one of the site aggregation units (“
- audited resource meter”
) by;(a) reading a present value measurement from the audited resource meter; (b) comparing the present value measurement to the resource measurement received and stored by the site aggregation unit to which the audited resource meter is sending the present value measurement; and (c) verifying the consistency of the resource measurement that is stored with the present value measurement.
