Abstract: An error correction method and a mobile communication device incorporating the error correction method. The error correction method begins with receiving fingerprint image information that includes a set of swatches. A first one of the received swatches is matched to a second one of the swatches at an edge. A measure of fingerprint image manipulation is determined responsive to an amount of processing to perform and an amount of fingerprint image error. Then the fingerprint image information is manipulated in response to an optimum value of the measure.
