Fingerprint matching

It's infallible science, used by criminologist to conduct matching nowadays using computers.

No two fingerprints are alike, even in identical twins – Sir Francis Galton (1893).

Henry system classified fingerprint ridges into eight categories: the central pocket loop, the double loop, the accidental, the plain arch, the plain whorl, the radial loop, the tented arch, and the ulnar loop.
Using Fingerprint Image Compression Standard, the FBI stores over 200 million fingerprints, out of which 29 million are unique and rest are from repeat offenders. The standard provides space-effective digital storage.
With time the technology becomes inexpensive and hence most businesses incorporate it for authentication purpose.

Several rare diseases like Epidermolysis Bullosa distort fingerprints or destroy them altogether, the victims have partial fingerprints or none at all.

Reliable, and Accurate Retina Scanning

The retina, an infinitesimally thin tissue which handles peripheral vision. It contains several layers – the outer layer contains reflective, photoreceptive structures called rods and cones that process light into electrical signals which get transmitted to the brain. Beneath this is the choroid layer having a complex blood vessel system.

The retinal patterns offer between 700 to 4200 points, much higher than a fingerprint, hence classed as high-biometrics. But the major issue is that it cannot be done on blind, partially blind or persons having cataracts. The retinal scans have inappropriately high false negative or rejection rate. Furthermore, the scan discloses personal information like signs of drug abuse, hereditary diseases, even AIDS. Hence maintaining the retinal pattern database could conceivably leave open to litigation. An employee may perceive them as a privacy violation.

The system fails to authenticate if the person had bronchitis, cold or laryngitis
