Patent 10097545 was granted and assigned to AT&T Intellectual Property I on October, 2018 by the United States Patent and Trademark Office.
Artificial biometric traits self-nullify due to natural physiological processes. Biometric enrollment and authentication may then be based on a life associated with the self-nullifying biometric trait. Once the life is expected to have expired, no further authentication may be performed until a new artificial biometric is applied.
