Abstract:
1. A metering device for metering a physical characteristic and for delivering information to a third party on the basis of collected metering information, the metering device comprising: signal collecting means operable to collect a metering signal comprising information relating to the metered physical characteristic, random signal generating means operable to generate a random signal on the basis of the received metering signal by: determining a distribution, in time, of the metering signal, and determining a probability distribution for the random signal on the basis of the distribution of the metering signal by maximizing a statistical distance between the probability distribution of the random signal and the distribution of the metering signal; signal processing means operable to process the metering signal and the random signal to produce a modified metering signal, and signal emission means operable to emit said modified metering signal to said third party.
