Question 1

What is 'poroscopy' in the context of fingerprint examination?

Accepted Answer

The study of pores in ridge skin used as an additional level of detail for identification

Answer

Poroscopy is the examination of the size, shape, and arrangement of sweat pores along ridges as an additional level of detail beyond Galton characteristics.

Question 2

Which of the following is NOT one of the three levels of fingerprint detail used in latent print examination?

Accepted Answer

Level 4 – sub-dermal layer comparison

Answer

Fingerprint examination uses three levels of detail: Level 1 (pattern), Level 2 (Galton ridge events), and Level 3 (pores and ridge edges); there is no Level 4 sub-dermal category.

Question 3

Which classification is used for a whorl pattern where one of the ridges makes a complete circuit and one delta lies inside or touched by the inner line of flow?

Accepted Answer

Central pocket loop whorl

Answer

A central pocket loop whorl has at least one ridge making a complete circuit and is characterized by a recurving loop that encloses a whorl center.

Question 4

When an examiner documents a fingerprint comparison, what is the primary purpose of charting or marking ridge characteristics on the prints?

Accepted Answer

To create a permanent record showing the corresponding points used to reach the conclusion

Answer

Charting ridge characteristics creates a documented, reproducible record of the specific corresponding features the examiner identified during the comparison.

Question 5

What does 'ridge dissociation' indicate about a fingerprint impression quality?

Accepted Answer

The ridges appear broken or discontinuous due to insufficient ink or pressure

Answer

Ridge dissociation occurs when ridges appear broken or fragmented due to insufficient ink or contact pressure during recording, reducing print quality.
