Systems and techniques are described herein for user identification. For instance, a technique can include receiving at least one biosignal from a sensor, the at least one biosignal indicative of a blood perfusion of a user. The technique can further include extracting at least one feature from the at least one biosignal, comparing the extracted at least one feature to at least one template feature associated with an enrolled user, determining, based on comparing the extracted at least one feature to the at least one template feature, whether the user matches the enrolled user, and outputting an indication of whether the user matches the enrolled user.
