Abstract
The private attestation is required in the various places of the societies and is always asked for high reliability and high convenience. However, in the main attestation method, the demerit such as disclosure, oblivion, forgery, and missing come out. Then, the private attestation using biometrics attracts attention in recent years as a new system. There are some which have already been put practical use in attestation by biometrics, but the picture which serves as the feature with scanning will be received a mental streess. Then, we aimed at realization of the simple private attestation which is possible only by showing up the palm without receiving these stresses in this reserch.
