%X There are two focuses in biometric applications, one is the traditional authentication and identification technology, and another is the key generation technology. The character code extraction from iris information, the random string extraction from character code using fuzzy method and the embedding of random string in the elliptic curve are studied. A new digital identity signature scheme based on iris information is proposed, which takes the iris information as the public key. Using two independent PKGs, the proposed scheme could avoid the signature forgeability of the single PKG, hence it has more security and reliability. With the random oracle model, the proposed scheme is proved to have the unforgeability secure when adaptively choose plaintext and identity attack, and it can  effectively resist the birthday attack.
