Patent Images

1. , based on an electronic document encrypting and decrypting device for iris recognition, comprise iris camera and main control chip module, wherein,Described iris camera, adopts optical anti-vibration to move iris camera, for gathering the iris of both eyes image information of granted access person;

  • Described main control chip module, comprises registration and identifies service unit, iris administrative unit, encrypting and decrypting unit;

    Described registration identification service unit is used for communicating with iris camera, iris feature value is extracted from the iris image of gathered granted access person, the iris feature value of registered in advance and the iris feature value of current collection are contrasted, judges whether the iris feature value of registered in advance mates with the iris feature value of current collection;

    Described iris administrative unit is used for calling iris cryptographic algorithm and produces key, and by key storage in the pool of keys of main control chip module;

    Described encrypting and decrypting unit is for selecting electronic document, prompting gathers iris image, from main control chip module pool of keys, take out encryption or decruption key, call iris cryptographic algorithm and electronic document is encrypted or deciphers, complete iris encryption or the deciphering of electronic document.
