observed print, are the special characteristics that make the fingerprint a specific identifying characteristic of each individual. There are at least 150 individual ridge characteristics on the average fingerprint. If between 10 and 16 specific points of reference for any two corresponding fingerprints identically compare, a match is assumed.
Ridge characteristics, also known as minutiae, are the fine details in the patterns of friction ridges found on the skin's surface, primarily on the fingers, palms, and soles.These unique ridge features are crucial in forensic fingerprint identification. No two fingerprints share the same arrangement of minutiae, making them a highly reliable method for personal identification.
Learn about the history, approach, and technology of fingerprint recognition, a biometric method based on the uniqueness and consistency of fingerprints. Find out how fingerprint features, minutiae, and algorithms are used for identification and verification.

These patterns are tented arches because they possess two of the characteristics of a loop, a delta and a recurve, but lack the third, a ridge count across a looping ridge. [Figs. 142-143] Figure 144 is a tented arch combining two of the types.
No.3: Fingerprint Patterns & Ridge Characteristics These features are present in the friction skin ridges, which leave behind impressions of its shape when it comes into contact with an object. The impressions from the distal phalanges are called as fingerprints. The ridge characteristics serve to individualize a person.
Type lines—The two innermost ridges that start parallel, diverge, and surround or tend to surround the pattern area (Figure 2.6).. Core—The approximate center of the fingerprint pattern.(A loop pattern has specific rules governing choices between cores.) The delta—The delta is that point on a ridge at or in front of and nearest the center of the divergence of the type lines (Figure 2.6).
A fingerprint characteristic that comes out of the side of the ridge and suddenly stops in between ridges. Eye A fingerprint characteristic in which two ridges connect at two points to create a space in the middle.
A fingerprint pattern type where the friction ridges make a complete circuit around the centre of the fingerprint. This pattern consists of two deltas, one on either side of the core, which is encircled by multiple concentric circular ridge patterns. This pattern is an example of a first-level fingerprint detail.
Analysts use the general pattern type (loop, whorl or arch) to make initial comparisons and include or exclude a known fingerprint from further analysis. To match a print, the analyst uses the minutiae, or ridge characteristics, to identify specific points on a suspect fingerprint with the same information in a known fingerprint.

Ridge counting from delta to core which has the least number of ridges. Rules of Ridge Counting of Loops. The following are ten rules that are used in the ridge count of loops in fingerprint patterns: Rule 1: Choosing Core and Delta. Make sure the fingerprint has a loop pattern with one core and delta. Locate the exact position of the core and ...

Fingerprint Analysis and Representation 3.1 Introduction A fingerprint is the reproduction of a fingertip epidermis, produced when a finger is pressed against a smooth surface. The most evident structural characteristic of a fingerprint is a pattern of interleaved ridges and valleys; in a fingerprint image, ridges (also called ridge lines) are
