The current encryption algorithm has some problems that key length is long, which is difficult to be memorized and kept so that a potential threat is caused to information security. The encryption key extracted from the biological feature is used for the encryption method, which has become a hotspot of the research. The Haar wavelet decomposition is carried out to the iris image, to extract the third-layer high frequency coefficient as the iris feature code. The random mapping function is used to generate a 128 - bit key. chi-square (χ2) test is used to analyze the key safety extracted. The results show that the key extracted from iris feature can meet requirements of the randomness and security of the encryption algorithm.
