• DNA BIOMETRICS: DNA, standing for deoxyribonucleic acid, is an

organic biochemical compound that holds all the genetic information

of a person. Due to its individuality and uniqueness, it plays an im-

portant role in identification. DNA biometrics is done using the bio-

logical samples left at the crime scene. The biological samples can be
the hair strands of a person, saliva, semen, or anything else that holds

biological information about a person. The usage of DNA for analysis

is said to be DNA profiling in forensic science.

• PALMPRINT BIOMETRICS: Besides fingerprints, palm prints also
play an important role in forensics. They have the same patterns,

valleys, and ridges as on fingertips. They do play an important role

in identification. The area of the palmar region is much higher and

broader than that of the fingers, so the palm print databases in palm

print biometrics provide a positive identification for investigators.
