| Summary: | 碩士 === 中國文化大學 === 資訊管理學系 === 98 === In RFID systems, tags and readers is based on two main components of the way radio frequency data signal transmission, compared to the existing bar codes, RFID provides the entire batch at the same time to read and read and write characteristics of a great deal of information. Existing RFID system as a result of the general lack of reliability and vulnerability factors such as noise interference, resulting in read rate of 100% cannot be reached, it is proposed in this paper to prove the basis of a set of groups to join cross-certification through the label information has been stored, so that the label with the group of mutual authentication, this method can effectively reach all of the reading and authentication, and therefore to read in this article referred to reliability, it includes a read rate of upgrading, as well as read the information is correct.
