Q.1: What is the name of the unique pattern found in the ridges of a fingerprint, which is the basis for fingerprint identification?
Ans.: The unique pattern found in the ridges of a fingerprint is called a “ridge pattern.”
Q.2: What are the three primary types of fingerprint ridge patterns?
Difference Between Conventional And Modern Methods For Examination Of Fingerprints
Ans.: The three primary types of fingerprint ridge patterns are arches, loops, and whorls.
Q.3: What part of the finger is responsible for leaving latent fingerprints on surfaces?
Ans.: Latent fingerprints are primarily left by the sweat and oil residues from the friction ridge skin, specifically from the sweat pores located within the ridges.
Q.4: Which method of fingerprint collection involves using black powder or magnetic powder to make latent prints visible?
Ans.: The method of fingerprint collection involving black powder or magnetic powder to make latent prints visible is known as “dusting.”
Q.5: What is the term for the process of comparing a latent fingerprint to a known fingerprint for identification purposes?
Ans.: The process of comparing a latent fingerprint to a known fingerprint for identification purposes is called “fingerprint matching” or “fingerprint analysis.”
Q.6: What is the purpose of fingerprint databases like the Automated Fingerprint Identification System (AFIS)?
Ans.: The purpose of fingerprint databases like AFIS is to store and search for fingerprints from crime scenes to identify potential matches with known individuals in law enforcement databases.
Q.7: What is the name of the layer of skin that contains sweat glands and is responsible for the formation of friction ridge skin?
Ans.: The layer of skin responsible for the formation of friction ridge skin is the “dermal layer” or “dermis.”
Q.8: What is the term for the process of digitally scanning and storing fingerprints for identification purposes?
Ans.: The process of digitally scanning and storing fingerprints for identification purposes is called “fingerprint biometrics” or “fingerprint scanning.”
Q.9: What is the minimum number of matching points typically required for positive fingerprint identification?
Ans.: The minimum number of matching points required for positive fingerprint identification can vary but often follows a threshold of around 12 to 16 matching points.
Q.10: In fingerprint analysis, what is the term for a feature or characteristic of a fingerprint pattern, such as a ridge ending or a bifurcation?
Ans.: In fingerprint analysis, a feature or characteristic of a fingerprint pattern, such as a ridge ending or a bifurcation, is referred to as a “minutia.”
