Short Content: 1 introduction 　　The fingerprint recognition technology through the analysis fingerprint's partial characteristic, extracts the exhaustive characteristic point, thus confirms individual status reliably. The fingerprint recognition's merit is the fingerprint takes the human body unique characteristic, its order of complexity may provide the enough characteristic which uses in distinguishing, has the extremely high security. Is opposite in other status authentication technology, the fingerprint recognition is one more ideal status authentication technology, the fingerprint recognition not only has many original information security ...
