Technology Marketing SummaryA number of biometric parameters exist for positive identification of individuals including, fingerprints, facial recognition, ear pattern, eye iris and retina, written signature, voice, and facial thermogram. The objectives of personal identification are primarily to deter identity deception and to accelerate recognition of trusted personnel. The use of current methods for positive identification is impacted by a number of factors including universality, uniqueness, permanence, collectability, performance, acceptability, and circumvention.DescriptionResearchers at ORNL have developed a novel method of identifying and authenticating individuals, which offers improvement over current methods through increased performance, robustness, and reliability, while preventing circumvention of the system. The method uses brain wave data uniquely formed from an individual’s thought process. The brain waves are sampled using EEG equipment and processed using phase-space distribution functions to compare digital signature data from the enrollment of authorized individuals. The developed method provides authentication (verification that test and enrollment biometric data are confirmed to be the same) and identification (determination that enrollment and test biometric data match to identify an individual among others).

The technology could be utilized for organizations requiring very high assurance of a person’s identity including federal/state/local government and financial institutions.

Methods for using a biometric parameter in the identification of persons
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.
