Voice Recognition
Voice recognition is the ability of a technological program to analyze sound and identify spoken voices.
-
-
Voice recognition is especially useful because it allows hands-free commands to be carried out in practical uses.
The AI or program of the voice identifier will scan and analyze the voice, comparing it to the desired voice 'fingerprint'.
Iris/Retina Scan
Iris Scan is scanning the part in your eye which is called Iris. It is located in the eye pupil which is behind the coronea.
The iris is a thin, annular structure in the eye, responsible for controlling the diameter and size of the pupil, thus the amount of light reaching the retina.
-
Disadvantages
Generally require close proximity to camera, which can cause discomfort for some.
Can't use a regular camera; requires IR light source and sensor. Visible light must be minimized for highest accuracy required for search.

Handwriting
Handwriting recognition is the technology that analyzes and identifies the style of writing from a person.
Static - the user would write it on a piece of paper, scan it with a camera, and the system would analyze the patterns and shapes.
Dynamic - the user would write it on a tablet or so, digitally, and the device would measure the pattern, stroke, pressure, and coordinates.
DNA profiling
It allows DNA samples from different people to be compared to look for similarities and differences.
It is very accurate. easily storable, can help find evidence and find relatives
-
Palm scan
The palm contains of principal lines, wrinkles (secondary lines), and epidermal ridges. It also contains other information such as texture, indents, and marks which can be used when comparing one palm to another.
A palm vein scan is an image of a person's unique palm vein pattern obtained with special equipment.
Fingerprint Scan
A technology of capturing the pattern of valleys and ridges on the surface of a fingertip and then processed by the device’s pattern analysis/matching software, which compares it to the list of registered fingerprints on file.
-
For example: if your device fingerprint was identified as a new visitor, an advertisement could be displayed about a deal or sale that can only be used once.
