The three primary fingerprint patterns are arches, loops, and whorls.
2. What are minutiae points, and why are they important in fingerprint identification?
Minutiae points are specific ridge characteristics like ridge endings and bifurcations. They are
important because they provide unique features used for fingerprint matching.
3. What is AFIS, and how does it assist fingerprint identification?
AFIS stands for Automated Fingerprint Identification System. It's a computerized database that
helps match unknown fingerprints with known prints, making the identification process faster
and more efficient.
4. Why is proper fingerprint collection important in forensic analysis?
Proper collection ensures clear and accurate prints, which is essential for reliable fingerprint
analysis and identification.
5. What is the difference between individualization and absolute uniqueness in fingerprint identification?
Fingerprint analysis aims to establish individualization, meaning that no two individuals have
been found to have identical fingerprints. It doesn't claim absolute uniqueness but is a highly
reliable method for personal identification.
