Fingerprints & Dermatoglyphics:
Diagnostics beyond Identity!
FINGERPRINT DISTRIBUTIONS & HAND DIAGNOSTICS: HOW TO UNDERSTAND FINGERPRINTS ON THE FIVE FINGERS?
What else can fingerprints reveal
beyond your identity?
It's not a public sectret: every single fingerprint has tiny characteristics that are unique to each person.
But not all aspects of a fingerprint are unique!
For example: fingerprint pattern types vary significantly among males and females; and fingerprints also tend to vary among the populations around the world.
But what else can fingerprints reveal?
Diet, lifestyle, disease & personality can approximately be determined via fingerprints.
This section also includes a new approach for assessing the significance of the combination of the 5 fingerprints in any hand!
The history of fingerprinting started long ago.
In quite a few ancient cultures fingerprints have been used as an item of decoration.
And fingerprints are known to have been used as signatures as early as the second millenium BCE.
But it took about 3 millenia since then before a fingerprint was recognized as a tool for identification.
In 1880, Dr Henry Faulds, a surgeon in a Tokyo hospital, published his first paper on the subject in the scientific journal Nature, discussing the usefulness of fingerprints for identification and proposing a method to record them with printing ink.
But his ideas were rejected at that time.
|And it took another 12 years before Sir Francis Galton published in 1892 a detailed statistical model of fingerprint analysis and identification and encouraged its use in forensic science in his book Finger Prints.
Galton calculated that the chance of a "false positive" (two different individuals having the same fingerprints) was not higher than about 1 in 64 billion.
Sir Francis Galton.
Galton's work also served as the first milestone in the scientific study concerning the classification of fingerprint types.
His method for fingerprint type classification e.g. focussed on the significance of the so-called 'delta' (triradius), which resulted in 3 basic fingerprint types: the whorl (2 deltas), loop (1 delta), and arch (no delta).
And Galton's approach is still visible in the F.B.I. approach of fingerprint classification groups that is used around the world today - which includes a sub-division of Galton's types into 8 fingerprint types.
But there are (less detailed) classification systems available featured with my more fingerprint types.
THE F.B.I. APPROACH TO FINGERPRINT TYPS:
- I ARCHES -
Ia plain arch - Ib tented arch
- II - LOOPS -
IIa ulnar loop - IIb radial loop
- III - WHORLS -
IIIa plain whorl - IIIb central pocket loop - IIIc double loop - IIId accidental whorl
At the end of the 19th century fingerprints were discovered as a valuable tool for the purpose of personal identification.
And due to this discovery fingerprints not only became a valuable tool in the forensic sciences, fingerprints now also have become a valuable security tool - which is applied in many biometric systems, such as: fingerprint timeclocks, fingerprint computer security, fingerprint cell phone security, and fingerprint attendance systems.
In the 20th century researchers have discovered that fingerprints can reveal so much more beyond theme 'identity'.
Because studies have unvealed that fingerprints reveal clues that relate to other themes, including: sexe, race, diet, lifestyle, and disease.
And early in 2016 a new perspective became available involving how fingerprint patterns bare the potential to correlate most likely with personality & temperament. ...more
What will be the outcome of the 21 century?
While fingerprint pattern type distributions have been studies on the individual fingers, researchers have presented few attempts focussed on studying the significance of the 5 fingers together.
In this section a new approach will be presented which shows why the significance of the fingerprint type on the pointer finger is more important than the fingerprint types seen on the other four fingers (thumb, middle finger, ring finger & pinky).
In order to keep things simple, this new approach is focussed on studying the significance of the 4 most common (major) fingerprint types: the ulnar loop, whorl, radial loop and arch.
ULNAR LOOP - WHORL - RADIAL LOOP - ARCH
