1. A method for a health scanning system, the method comprising: receiving an initial physiological data stream for a known user; calibrating a scanner to the known user to obtain a calibrated noise signature for the initial physiological data stream of the known user; storing the calibrated noise signature for the known user into a noise signature database associated with profile information for the known user; receiving a subsequent physiological data stream from an unknown user; extracting a noise signature from the subsequent physiological data stream for the unknown user; and comparing the extracted noise signature with the calibrated noise signature in the noise signature database to determine a match or no match; wherein a match is determined for the unknown user to validate as the known user and the method further includes extracting the profile information from the noise signature database for the known user; allowing the unknown user to access user medical records associated with the known user; and appending the profile information to the subsequent physiological data stream to store as a part of the user medical records associated with the known user.
