Fingerprints are created by the elevated ridges on the fingertips, which leave impressions on things. It is essential to a person's identification because of how special it is. The level 1 feature is an overall ridge flow pattern. Ridge characteristics, also known as minutiae, make up the level 2 features of a fingerprint and are the particulars of each ridge. Level 3 features of a fingerprint include pore morphology and characteristics as well as fingerprint ridge density (FPRD), which are precise and useful for identifying a specific person. All of these characteristics aid in identification when the epidermis is broken by any kind of damage, such as burns or prolonged submersion in water. Finger phalanges can be difficult to identify and subject to forensic analysis when submerged in water for an extended period of time. This study involved subjects between the ages of 21 and 35 and was conducted among the Indian population. The left hand's thumbprints were recorded using kores ink over fingerprint slips both before and after being submerged in water for various amounts of time. The goal of this research is to examine how ridge characteristics and pore morphology are affected by water submersion for fingerprint analysis. The number of tiny particles found in post-submergence prints was found to be decreasing in a small number of subjects when compared to pre- submergence prints, and round, closed, medium-sized pores were most frequently found. Additionally, it was discovered that pre-and post-submergence fingerprints had a significant mean difference in ridge density. The results of the current study will be extremely important in drowning cases where fingerprints are anticipated to be used for personal identification.
