Tenprint Fingerprint Certification Tenprint Fingerprint Classification Systems 2

Question 1

What is the 'final' in the Henry Classification System?

Accepted Answer

The ridge count of the right little finger loop

Answer

The final is the ridge count of the right little finger if it is a loop pattern, used to further differentiate similar classifications.

Question 2

Which pattern type is assigned a value in calculating the Henry primary classification?

Accepted Answer

Whorl

Answer

Only whorls contribute numerical values in the primary classification formula; arches and loops count as zero.

Question 3

In the NCIC fingerprint classification system, how are patterns encoded?

Accepted Answer

Using a single uppercase letter per finger

Answer

The NCIC system uses a single uppercase letter to represent the pattern type for each of the ten fingers in sequence.

Question 4

What does 'ridge tracing' determine in whorl classification?

Accepted Answer

Whether a whorl is inner, meeting, or outer based on tracing from the left delta

Answer

Ridge tracing follows the ridge from the left delta and classifies the whorl as inner (I), meeting (M), or outer (O) relative to the right delta.

Question 5

What is the 'major division' in the Henry classification system based on?

Accepted Answer

The pattern types on the thumbs

Answer

The major division uses the pattern types found on the thumbs and further subdivides the classification based on ridge count or tracing.
