Abstract:
1. An image verification method comprising: sensing a first fingerprint using a fingerprint sensing means; storing image data of the first fingerprint sensed by the fingerprint sensing means as a first image data using an image data storing means; comparing a second image data of a second fingerprint sensed by the fingerprint sensing means with the first image data using a residual fingerprint judging means, wherein the fingerprint judging means judges whether the second image data is a residual fingerprint; and verifying the second image data image data using a verification means, when the residual fingerprint judging means judges that the second image data is not a residual fingerprint; wherein the residual fingerprint judging means judges that the second fingerprint is a residual fingerprint when the first image data and said second image data match, and judges that the second fingerprint is not a residual fingerprint when said first image data and said second image data do not match, and wherein the residual fingerprint judging means performs the steps comprising
