Palm Print Identification in Forensic Sciences – ForenScope
Gender differences in palm print ridge intensity can help identify a dismembered hand during forensic investigations to identify an individual in mass disasters/mass murder cases. Important features of palm print identification are geometric, basic, wrinkled, delta point, and minutiae (small) features.
Palm Print in Forensics: #Types, Importance, Classification, …
For studying palm prints as forensic evidence, they can be divided into four major types. These are (1) Visible, (2) Latent, (3) Patent and (4) Plastic palmprints. 1. Visible Palm Prints.

In palms containing only three interdigital deltas, the most common configuration was a delta under the index, middle, and little finger each (the ring finger delta was absent): 31 of 32 left palms and 19 of 19 right palms with three interdigital deltas were missing the ring finger delta.

Triradial point or triradius is located at the meeting point of three opposing ridge systems. A triradius is often described as a delta but a distinction can be made between them. A delta is a triangular plot whereas a triradius is represented by ridges forming its boundary. Thus a triradius may be present if there is no true delta.
Palm print - Wikipedia
A palm print is an image acquired of the palm region of the hand. It can be either an online image (i.e. taken by a scanner or CCD) or offline image where the image is taken with ink and paper. [1] The palm itself consists of principal lines, wrinkles (secondary lines), and epidermal ridges.

Delta : A point in loop and whorl prints that lies within an often triangular, three pronged or funnel shaped structure; it is the part of a ridge nearest the point where two parallel ridge lines (the “type” lines) diverge to flow around the loop or whorl; loop patterns have one delta, which is the starting point for conducting a ridge ...

Starting at the left delta, trace ridges, moving outward away from the center of the pattern to where the ridge ends. Continue tracing until the point nearest or opposite the extreme right delta is reached.
