First Claim

1. A method for processing data to provide positive identification of a person, comprising:
- acquiring a plurality of sets of data for at least one channel of human brain wave data from at least one first person for the purpose of providing an enrollment signature;
acquiring a plurality of sets of data for at least one channel of human brain wave data from at least one second person for the purpose of providing a test signature;
computing at least one measure of dissimilarity between the enrollment signature and the test signature for distribution functions derived from at least one of a connected phase space and a non-connected phase space;
comparing said measure of dissimilarity to a threshold in which exceeding the threshold results in non-confirmation of an identity of the second person being also an identity of the first person and in which not exceeding the threshold results in confirmation of the identity of the second person being also the identity of the first person; and
signaling an observer that the second person'"'"'s identity has either been confirmed or not confirmed.

Abstract
Brain waves are used as a biometric parameter to provide for authentication and identification of personnel. The brain waves are sampled using EEG equipment and are processed using phase-space distribution functions to compare digital signature data from enrollment of authorized individuals to data taken from a test subject to determine if the data from the test subject matches the signature data to a degree to support positive identification.

7. A method for new use of brain wave data, the method comprising:
-
computing a measure of dissimilarity for at least one distribution function derived from at least one of a connected phase space and a non-connected phase space for brain wave data providing an enrollment signature for a known human person and for brain wave data providing a test signature from a test human person; comparing said measure of dissimilarity to a threshold in which exceeding the threshold results in non-confirmation of a test human person'"'"'s identity being that of the known human person and in which not exceeding the threshold results in confirmation of the test human person'"'"'s identity being that of the known human person; and signaling an observer that the test subject'"'"'s identity has either been confirmed or not confirmed. - View Dependent Claims (8, 9, 10, 11, 12, 13)
