# Liverpool Palm Print Classification System: How to Calculate Values?

Liverpool Palmprint Classification System (LPCS) is one of the easy-to-understand palm print classifications whose values are in alphabetic and numeric code arranged in special coding boxes. It was housed in Liverpool, England.

## How to Calculate Liverpool Palm Print Classification Values?

### A. Primary Division

The primary division uses a set of values based on any type of pattern that appears in any of the three palm sections. In the case of more than one pattern in a palm area, even then, only a single value is given.

#### Table for Pattern Indication from Primary Values

However, if patterns appear in more than one palm section, then cumulative summed values in assigned all values are given in the following table.

### B. Secondary Classification

Secondary palmprint classification has another extension called subsecondary classification. The values are governed by the pattern in the hypothenar part only and are assigned as the alphabetic code.

More than one Pattern in Hypothenar Area:

The classification box is separated by a diagonal line (bottom left to the upper right).

• Left Upper Half: designated the pattern symbol of the pattern closest to the interdigital area.
• Lower Right Half: designated for the pattern symbol of the pattern closest to the wrist.

Following are the alphabetic codes used in secondary classification:

#### Second Subsecondary Classification

It involves two subclassifications:

• Single loop in the hypothenar: record the number of ridge characteristics in the core area.
• Devoid pattern in hypothenar: record the type of delta.

### C. Tertiary Classification

The thenar section of the palm is used to obtain the value of this classification.

Like primary classification, if two patterns are in the thenar area, the box was separated by a diagonal line.

• Left Upper Half: designated the pattern symbol of the pattern closest to the interdigital area.
• Lower Right Half: designated for the pattern symbol of the pattern closest to the wrist.

### D. Quaternary Classification

The quaternary classification is subdivided into three divisions:

• Part 1
• Part 2
• Part 3

#### Part 1 of Quaternary Classification

• Types of patterns in the interdigital area.
• More than one pattern in the area, a diagonal box separated by three diagonal lines.
• Upper left third: pattern closest to the index finger
• Botton right third: pattern closest to the little finger

#### Part 2 of Quaternary Classification

• Specific predetermined numerical values indicate the position of the pattern in relation to fingers.
• More than one pattern: combined the numeric values into a single value.
• Pattern between the base of two Fingers: record the higher value.

Following is the table for the given set of values:

#### Part 3 of Quaternary Classification

• Record counts of tented arches or loops (inward core, outward core, and downward core loops) in the interdigital area.
