1. A method for generating a cancelable biometric, comprising: providing at least one texture image as at least one image pattern including binary pixels in a row-column format; generating a segmented image from an iris image; converting the segmented image of the iris image to an unwrapped iris image, where the unwrapped iris image includes binary pixels in a row-column format; combining the at least one image pattern with the unwrapped iris image by employing a transform pixel operation that includes applying a logical XOR operation or a logical XNOR operation to combine the binary pixels of the at least one image pattern with the binary pixels of the unwrapped iris image and generate a transformed enrollment such that information about the transform pixel operation and the at least one image pattern form a security key for protecting the unwrapped iris image; and if a new security key is needed, reusing the unwrapped iris image to generate the new security key to permit a previous security key to be cancelable.
