1. A process of recording biometric features in a computer recordable medium to reduce storage space required to store the biometric features, comprising the steps of:
extracting a raw biometrics feature of one or more biometric patterns comprising finger prints, palm prints, iris images, and retina images;
segmenting each one or more raw biometric patterns into at least two regions;
identifying anchor features and at least two other significant features in each of the at least two regions:
wherein the anchor feature consists of:
(a) a centre point in finger prints or palm prints,
(b) an optic disc in a retina image,
(c) a lens section in an iris image;
and wherein the significant features consist of:
(d) ridge join points or ridge line endings for finger prints or palm prints,
(e) macula and vessel density in a retina, and a lens and iris portion in an iris image;
computing positional relativity of each significant feature in relation to the anchor feature wherein the positional relativity includes one or more distance, direction or segment units;
computing the minimum and maximum value of the positional relativity of each feature;
concatenating the values obtained in the computing steps as a feature by compressing the values obtained in the computing steps by one byte per character; and
storing in the computer recordable medium of the feature obtained in the immediately preceding step,
wherein all of the steps are performed by a computer.
