Physical biometrics (sometimes called physiological or even static biometrics) refers to the collection and analysis of unique physical traits. These traits can identify individuals and measure their health markers.
While most often used for humans, physical biometrics can also apply to animals. Dog nose prints, for example, are analogous to human fingerprints; having nose prints records can help owners recover lost or stolen pets.
Nowadays, sensors, scans, MRIs, and wearable technology record physical biometrics data instantly. However, low-tech recordings still exist, such as fingerprints taken with ink on cardstock or heartbeat per minute recorded on paper after holding your fingers to your wrist for thirty seconds and doubling the number.
Due to the security and healthcare applications, most databases are either unavailable to the public or anonymized. Healthcare-related biometric data, however, abounds online and in libraries.
A large portion of this data is available in the form of images: fingerprints, faces, brain scans, etc. are only available as images. Machine learning programs then scan the images to find unique patterns that either identify individuals or identify irregularities that doctors should investigate.
Other data may appear in columns or charts, as desired. Heartbeat, perspiration, respiration in response to stimuli, etc. are more clearly understood in a time series.
Commercial, public, and other organizations use physical biometric data to enhance security. Often, they combine biometrics with traditional measures like passwords to increase security.
Healthcare providers and individuals also use this data to measure health and to measure individual progress on health or fitness-related goals.
A security-related physical biometrics data set should be large enough to differentiate between individuals in the data set. However, if it is too large, the machine learning program loses efficacy.
Healthcare-related physical biometrics data, on the other hand, records new data alongside past data in order to track progress. This is true whether the data set measures an individual or a population.
In all cases, the data recorded must be clear (if an image), complete, and up-to-date.
Tech5 has launched an updated facial recognition engine for touchless access control and time and attendance applications, with built-in mask detection.
The new T5-Face is suited for use in products designed for identification of people in non-cooperative situations, regardless of challenges like partial facial occlusion with masks or sunglasses, or poor lighting, according to the announcement. In cooperative-subject applications, or implemented on mobile devices, the system may ask people to lower their masks for faster and more accurate identification.
