Breathprints?
When fingerprints or gait-analysis isn't enough. There is now Breath-analysis or prints. The way you breath is apparently also individual and somewhat unique. Also you just can't stop breathing to hide from the Man. Will people wear scuba gear on land so not to reveal or leave their breathprints? Considering they need to put a device on the back of your neck it seems unlikely.

The researchers developed a device that precisely monitors and logs the airflow through each nostril of the wearer. Then, they tasked 97 study participants with wearing the device for up to 24 hours. From just one hour of recording, the researchers achieved an accurate identification rate of 43 percent, Soroka said. This accuracy skyrocketed at 24 hours.

The resulting breath log was then analyzed using a protocol known as BreathMetrics, which examines 24 parameters of the individual's nasal respiration.

The researchers did not just find that an individual can be confidently identified based on their breathing pattern; the results also revealed what those breathing patterns can indicate about a person.
