PERMANENCE OF THE FRICTION RIDGES OF THE PINEAPPLE FRUIT VENDOR: A CASE STUDY IN BELAGAVI CITY.

Abstract

Fingerprint recognition is one of the successful methods used for person identification, which takes 
advantage of the fact that the fingerprint has some unique characteristics called minutiae. 
Fingerprints are considered as permanent and doesn’t change even as people age. Although they 
remain permanent and unique, fingerprints are absent in some rare conditions like leprosy, 
mutilation, some rare skin disorders, medical condition like adermatoglyphia, old age etc. The 
present research article intends to study the effects of Bromelain on the fingerprints of pineapple 
fruit vendors to specifically test the permanence principle. Bromelain is an acid present in the 
pineapple fruit. It is unearthed that because of the chemical bromelain in pineapple, the fingerprints 
of fruit vendors tend to dissipate which is still unproved. Here the photographs of fingerprints of 
concerned fruit vendors will be collected using a controlled and experimental method. The 
controlled samples will be the fingerprints of other fruit vendor and the experimental samples will 
be the fingerprints of pineapple fruit vendor. Thus, the comparative study between the controlled 
and experimental samples will be conducted in order to test the hypothesis.
