A metering scheme is a protocol in which an audit agency is able to measure the interaction between clients and servers on the web during a certain number of time frames. Naor and Pinkas [7] considered metering schemes in which any server is able to construct a proof to be sent to the audit agency if and only if it has been visited by at least a number, say h, of clients in a given time frame. In their schemes the parameter h is fixed and is the same for any server and any time frame. In this paper we introduce dynamic multi-threshold metering schemes, that are metering schemes in which there is a threshold associated to any server for any time frame. We mainly focus on the efficiency of dynamic multi-threshold metering schemes, by minimizing the information received and distributed by clients. This is important because the clients participating in the metering process do not receive any money from the audit agency.
