Abstract
In this paper a new algorithm is suggested to encrypt data, as it was to benefit from human iris as one of Biometric properties in human body which distinguish the individual from the other to produce the encryption through extracting important features using Wavelet Transformation and then passing through a series of operations moderation as the first phase, at the second phase a chaotic function properties is used by leading it in encryption operation as a basic factor.
Through the overlap between the results of above phases a new encryption algorithm is produced which show strength, and could not discover the encryption key until getting the biometric property and finding complete information about the chaotic used function in addition to the working algorithm .
