By using the two-dimensional barcode encryption technology with pseudo fingerprint feature key, an asymmetric, encrypted and anti-fake design of two-dimensional barcode has been implemented. After being processed , the collected fingerprint information is used to set parameters, translated and rotated. With the accomplishment of coding the parameters, datas of pseudo-random fingerprint feature come into being. With the help of the RSA, encrypt the private key which is randomly produced by pseudo fingerprint feature to get a new one. With the new private key,the only information of owners is encrypted, solving the problem of "witness identity" .
Abstract. The security and privacy problem of low-cost RFID system is one of the most difficult conundrums in the RFID research field. A protocol based on access control was proposed in this paper, which used the reader access, partial ID, XOR operation, etc. By using of the reader authority distribution method, the unauthorized tag`s information was prevented give-away and it can avoid the lawful reader attack, location privacy attack, etc. Function of the reader was fully used. At the same time, the back-end database`s load and the time of the tag`s answer were reduced. Compared with several traditional security authentication protocols, this protocol is more security, lower energy consumption and more suitable for low-cost RFID system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
