A minutiae encryption algorithm based on geometric transformation of minutiae positions is proposed to generate cancelable fingerprint templates. A geometric transformation is used for alignment. A parameter-controlled minutiae encryption is performed within a local area to generate a cancelable minutiae template, and then all local encryption results are superimposed to form a protected template. Parameters to control the minutiae encryption are generated independent of the geometric-aligned minutiae, which ensures solid non-invertibility compared to those cancelable template generating algorithms with to-be-encrypted minutiae information as parameters.
