• Central Pocket Loop Whorl - C c
• Double Loop Whorl - D d
• Accidental Whorl - X x
• Points of Similarity - Minutiae on two different fingerprint impressions meet the criteria.
• Points of dissimilarity - Minutiae do not meet these criteria.
• Points of identification - Sufficient minutiae are located in the same true relative sequence or unit relationship, then identification is assumed.
• Poroscopy - is the study of the size, shape, relative position, arrangement ard frequency of sweat pores
• Edgeoscopy - is the study of the friction ridge edges for their alignment and the shape of their ridge units, as well as the shapes and alignments of pores close to the ridge edges which appear as notches
• Analysis - also highlights the assessment for the causes/factors of distortion and the upon the latent print is performed.
• Poor Clarity - Note how the friction ridges have become diffuse. There is a lack of distinction between the edges of the ridges and the intervening valleys.
