Reference: The Primary Classification Analysis
The purpose of the primary classification is to provide a description of the number of whorl patterns in a ten set of fingerprints; which is provided as a mathematical expression. In essence, the primary classification sequence would constitute a range of whorl patterns from the appearance of no whorls over the ten set, (represented by the code of 1 over 1) to the appearance of whorls in each of the ten digits, (represented by the code of 32 over 32). All together there are 1024 primary classification codes from 1 over 1 to 32 over 32.
The way that this is accomplished is to assign a numerical value to each of the ten digits. When a whorl appears in a given digit the digit receives the assigned numerical value. In addition, all digits are assigned a number to identify its placement upon the given hand. Digits 1,2,3,4, and 5 represents the right hand with digit 1 as the right thumb and digit 5 as the right little finger. Digits 6,7,8,9, and 10 would represent the left hand with digit 6 as the left thumb and digit 10 as the left little finger. A sequence chart can be provided in which the filing of the 1024 classifications can be displayed. It would show each classification, for example, 1 over 1 then 2 over 1 to 32 over 1 as the first line in the display, then 1 over 2 and 2 over 2 to 32 over 2 as the second line in the display. This sequence continues to the last line in the display which is 32 over 1 then 32 over 2 until 32 over 32 is reached in the display.
To file fingerprint records by the primary classification, a reasonable distribution of codes over the 1024 classifications had to be considered. Fingerprint technicians took into account the phenomenon of different populations across a geographical location and it was best determined that the ten digits should be assigned numerical values (in most cases) in the following way: 1=16, 2=16, 3=8, 4=8, 5=4, 6=4, 7=2, 8=2, 9=1 and 10=1.
Thus the total numerical values of the even digits plus 1 for consistency is reflected as the numerator of the primary code while the total numerical values of the odd digits plus 1 for consistency is reflected as the denominator of the primary code.
However, today most agencies or departments do not file fingerprints according to the Henry System of Fingerprint Classification and Filing, they are using the Automated Fingerprint Identification System (AFIS) and (IAFIS) entry and comparison to store and retrieve fingerprint minutiae.
In Fingerprint Geometric Analysis the concept of the primary classification is presented from a different perspective. The 1024 classification codes of the primary classification are displayed in a multi-sequential primary classification chart which is an example of the Fingerprint Diagonal Reverse Sequence Arrangement in which an individual code can display up to three different locations. Each code will have a unique geometric design on the chart, a design which is triangular or linear in appearance. Thus an identifiable and unique design for a given code can be established. Subsequently, an analysis of that design as well as its geometric relationship to the other codes and their design can be explored.
There is however additional adjustments. The numerical values are assigned to the digits in a different way. Here we take into account the frequency of whorl patterns over the ten set of fingerprints. Fingerprints on digits with a high frequency of whorls are assigned a lower numerical value while fingerprints with a low frequency of whorls are assigned a higher numerical value. This would make all pattern frequencies more equal to the other. As before the addition of 1 to the numerical value(s) for consistency is included and the values of the right hand is presented over the values of the left hand instead of the value of even digits over odd.
What is also essentially paramount to this analysis is the dimensions of the multi-sequential primary classification chart. The length of each side of the chart must be 9131 units of measurement to provide a perimeter 36524 units of measurement. The presentation of this on a monitor must be reflected in the computer application. In this way accurate information for analysis will be provided. This distinction has been reflected by the dimensions of the Great Pyramid Khufu at Giza, Egypt. The reason for this is because the Great Pyramid has a length on each side of its base as 9131 pyramid inches to provide a perimeter of 36,524 pyramid inches as a Sacred Geometry. 36,524 is the number of days in 100 years.
It is important to mention that the perimeter of 36524 pyramid inches of the Great Pyramid Khufu expresses three units of time; 365 for 365 days in a year; 52 for 52 weeks in a year and 24 for 24 hours in a day!
