1. , a kind of method for combining human body biological feature codes of converting fingerprint image into digital quantity, it is characterized in that, fingerprint collecting is formed the fingerprint die to carrier, the fingerprint die that collects on the carrier is segmented to form item by the general structural features in mind of fingerprint, the core architectural feature of item is segmented to form order again, order is carried out assignment to form the digital quantity value of corresponding fingerprint die, then with fingerprint digital quantity value and colour of skin digital quantity value, eyeball color digital quantity value, the sex digital quantity value, the blood group digital quantity value, year of birth algebraically word value, the connection of suffix digital quantity value is combined into the human body biological characteristics identity coding, and realizes according to the following steps:

  • (1), at first, fingerprint collecting is formed the fingerprint die to carrier, method is;

    with this finger first horizontal nodel line with the upper part by collecting by India side formula or electronics, infrared fingerprint image acquisition mode, and forever be saved in image on the paper or in the computer hard disc, that can reproduce this detail characteristics of fingerprints complete, clearly, be exactly the fingerprint die of this fingerprint;

    (2), the general structural features in mind of fingerprint die according to the fingerprint die is divided into it bow, dustpan, bucket, scar, mixes, do not have six;

    (3), the core architectural feature according to item is subdivided into order again, and order carried out assignment, to form the digital quantity value of corresponding fingerprint die, method is, core architectural feature according to item, be subdivided into 100 orders, all give propertyization, unique one by one value respectively to each order in 100 orders, thereby convert fingerprint image to the fingerprint digital quantity value;

    (4), then, the fingerprint digital quantity value is connected with colour of skin digital quantity value, eyeball color digital quantity value, sex digital quantity value, blood group digital quantity value, year of birth algebraically word value, suffix digital quantity value is combined into the human body biological characteristics identity coding, said colour of skin digital quantity value be the colour of skin with the nature person be divided into artificial yellow, the artificial white of white race of the yellow race, the artificial black of black race, palm fibre plant artificially brown, all the other also carry out assignment to it respectively for five orders such as all the other looks, to form each order digital quantity value its personalization, unique are arranged all;

    Said eyeball color digital quantity value is, eyeball color digital quantity value be the eyeball color with the nature person to be divided into black color eyeball be black, blue color eyeball for blue, yellow color eyeball for yellow, anophthalmus for colourless, all the other be difficult to confirm eyeball color person for all the other etc. five orders and respectively it is carried out assignment, to form each order digital quantity value its personalization, unique is arranged all;

    Said sex digital quantity value is, with nature person'"'"'s sex be divided into the women for woman, the male sex for the man, all the other for all the other etc. three orders and respectively it is carried out assignment, to form each order digital quantity value its personalization, unique is arranged all;

    Said blood group digital quantity value is, it is that O type, A type blood are that A type, Type B blood are that Type B, AB type blood are that the negative blood of AB type, RH is the RH type, all the other blood groups are for all the other six orders and respectively it is carried out assignment, to form each order digital quantity value its personalization, unique arranged all that nature person'"'"'s blood group is divided into O type blood;

    Said year of birth algebraically word value is, it is an order that year of birth generation of nature person is divided into per ten years, and respectively it is carried out assignment, to form each order digital quantity value its personalization, unique is arranged all;

    Said suffix digital quantity value is, is made up of some bit digital or English alphabet, optionally worked out and assignment by residence management unit.
