It is based on the analogy of fingerprint analysis used by the police who use 16 points of reference (whorls, breaks and ends in lines, etc. ) that appear to be unique for the pattern in question. They do not describe the pattern of the whole fingerprint only the 16 points of reference. In the fragrance odour-print then we go through a process of looking at the 26 attributes (A-Z) in the odour of a fragrance and quantify each attribute with a proportionate value. A true profile would require that we take both the main classification and the sub- classification, which is cowered in the second stage of our analysis.
