Patent Images
1. A method for identifying the owner of a portable device, comprising the steps of:
- computing a dynamic identification code at the portable device;
encoding the identification code into an acoustic signature at the portable device;
causing the portable device to transmit the acoustic signature over a voice line to a service provider;
decoding the acoustic signature into the identification code at the service provider;
transmitting the identification code from the service provider to a certification service;
generating indicia of the identification code at the certification service;
comparing the indicia of the identification code to a plurality of possible owners;
producing a true owner from the comparison; and
causing the certification service to transmit to the service provider a digital certificate corresponding to a digital signature of the true owner.
