Tenprint Fingerprint Certification Tenprint Fingerprint Classification Systems 1 — Questions and Answers
Question 1: Which classification system assigns a numerical formula based on the pattern types found in all ten fingerprints?
- Henry Classification System (Correct answer)
- NCIC Classification System
- Vucetich System
- Roscher System
Correct answer: Henry Classification System
The Henry Classification System assigns a primary numerical formula derived from whorls found in specific finger positions.
Question 2: In the Henry Classification System, which fingers are used to calculate the primary classification?
- All ten fingers
- Only the thumbs and index fingers
- Paired fingers in positions 2/7, 4/9, 6/1, 8/3, 10/5 (Correct answer)
- Only whorl-pattern fingers
Correct answer: Paired fingers in positions 2/7, 4/9, 6/1, 8/3, 10/5
The primary classification uses whorls found in paired finger positions (2&7, 4&9, 6&1, 8&3, 10&5) assigned specific numerical values.
Question 3: What is the secondary classification in the Henry system based on?
- Ridge counts of loop patterns
- Pattern type of the index fingers (Correct answer)
- Number of whorls on all fingers
- Delta positions on arch patterns
Correct answer: Pattern type of the index fingers
The secondary classification is determined by the pattern type found on the index fingers (positions 2 and 7).
Question 4: What does the subsecondary classification in the Henry system measure?
- The ridge count or ridge tracing of loops and whorls on specific fingers (Correct answer)
- The ink quality of the tenprint card
- The age of the subject at time of printing
- The number of arches present
Correct answer: The ridge count or ridge tracing of loops and whorls on specific fingers
The subsecondary classification uses ridge counts (for loops) or ridge tracings (for whorls) on index, middle, and ring fingers.
Question 5: Which fingerprint classification system is used in most Latin American countries and differs from the Henry system?
- Galton-Henry
- Vucetich System (Correct answer)
- Roscher System
- NCIC System
Correct answer: Vucetich System
The Vucetich System, developed by Juan Vucetich, is widely used in Latin America and classifies patterns differently than the Henry system.
Question 6: In tenprint classification, what does the term 'key' refer to?
- The encryption used for digital fingerprint files
- The ridge count of the first loop found scanning from the little finger (Correct answer)
- The pattern type of the thumb
- The total number of whorls across all fingers
Correct answer: The ridge count of the first loop found scanning from the little finger
The key is the ridge count of the first loop encountered when scanning fingers from the right little finger to the left little finger.
