Patent attributes
A method of producing idiosyncratic electronic emissions fingerprints from an electronic device is disclosed wherein emissions produced by the electronic device are collected and converted into one or more digital electronic fingerprints. The method contemplates a variety of emissions, such as electromagnetic emissions (including radio frequency emissions) and vibrational emissions (including audio emissions). The emissions fingerprints of various types extracted from an electronic device can be combined into more complex emissions signatures, and/or they can be combined with conventional electronic fingerprints or other idiosyncratic identifying data. A drift-test method for compensation and correction of emissions fingerprint drift is also disclosed.
