1. a kind of biological information processing method characterized by comprisingObtain the first biological information;

  • According to specific information and encryption method, the first biological information is encrypted, it is special to obtain biology to be identifiedReference breath, the specific information include random string, terminal unique identification and user key;

    Determine the similarity between the biological information of the registration of biological information to be identified and preservation;

    Wherein, describedThe biological information of registration is to be encrypted according to the specific information and the encryption method to the second biological informationIt is obtained after processing;

    When the similarity, which meets specific operation, executes condition, the specific operation is executed;

    Wherein, first biological information is the set that biological feature vector is constituted;

    Then according to specific information and encryption sideMethod is encrypted first biological information, obtains biological information to be identified, comprising;

    According to specific information and encryption method, is carried out at least one element that the biological characteristic vector includes irreversible addClose operation obtains biological information to be identified;

    The biological characteristic vector includes the first element and second element, and the first element is for indicating that biological minutia information existsThe abscissa in two-dimensional space where image, second element is for indicating biological minutia information in the two-dimensional spaceOrdinate;

    ThenAccording to specific information and encryption method, is carried out at least one element that the biological characteristic vector includes irreversible addClose operation obtains biological information to be identified, comprising;

    According to specific information and encryption method, include to each biological characteristic vector for constituting the first biological information firstElement and second element carry out irreversible cryptographic calculation, including following sub-step respectively;

    Sub-step one;

    using Encryption Algorithm 1 to the information aggregate being made of random string, terminal unique identification and user keyComputations are carried out, security information set is obtained;

    Sub-step two;

    security information set is encrypted again using Encryption Algorithm 2, the safety after obtaining encryptionInformation aggregate;

    Sub-step three;

    each biological characteristic vector for being included for the first biological information executes operation respectively;

    according to addingClose treated security information set, the height value of image and width value and coordinates transformation method, in biological characteristic vectorThe first element and second element converted respectively, the first element and second element after being converted.
