Abstract
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.

A system, comprising:
- a hardware processor;
- and
- a memory device, the memory device storing instructions, the instructions when executed causing the hardware processor to perform operations, the operations comprising:
- processing a digital image associated with an authentication request, the digital image representing a nullifying artificial biometric;
- determining an expiration time associated with when the nullifying artificial biometric will self-nullify;
- and
- denying the authentication request after the expiration time associated with when the nullifying artificial biometric will self-nullify.
A method, comprising:
- processing, by a server, a digital image associated with an authentication request associated with a device, the digital image representing a nullifying artificial biometric;
- determining, by the server, a self-nullification associated with the nullifying artificial biometric represented by the digital image, the self-nullification occurring after an expiration of a time;
- and
- denying, by the server, the authentication request after the self-nullification of the nullifying artificial biometric at the expiration of the time.
A memory device storing instructions that when executed cause a hardware processor to perform operations, the operations comprising:
- processing a digital image associated with an authentication request, the digital image representing a nullifying artificial biometric;
- determining an expiration at when the nullifying artificial biometric will self-nullify;
- and
- denying the authentication request after the expiration at when the nullifying artificial biometric self-nullifies.
