| Popis: | 104 With the development of current technologies, information security has gotten much attentions; especially for user’s identification.For the existing biometric recognition systems, finger vein has the characteristic that it only accepts living body and having high recognition rate but it is adapt to the displacement of fingers. On the other hand, the size of the database is increased day by day; the recognition time is increased relatively. How to reduce the effect of the displacement of fingers and the recognition time becomes the major factor for the performance of the developing system. In order to improve the recognition rate and reduce the recognition time, this thesis divides the whole recognition system into two stages.The first stage measure the difference between the incoming user and the database and retrieve several candidates only for the second stage.The second stage will then go through the recognition based on the characteristic points and finally confirm the identity.In this thesis, the recognition system has been implemented in personal computers, embedded systems and mobile devices. Not only the execution time reduced significantly but also the recognition rate improved outstandingly. Having great variety of developed platforms, the proposed systems can be more useful and convenient for users. |
