Idology and Its Applications

Fraud (swindling money or property by utilizing fictional, counterfeit, forged, or imitative things or by feigning other persons) forms its threats against public security and network security. Anti-fraud is essentially the identification of a person or thing. In this paper, the authors first propose the concept of idology  a systematic and scientific study of identifications of persons and things, and give the definitions of a symmetric identity and an asymmetric identity. Discuss the conversion of a symmetric identity like a fingerprint to an asymmetric identity. Draw a comparison between a symmetric identity and an asymmetric identity, and emphasize that a symmetric identity cannot guard against inside jobs. Make a comparison between a RFID and a BFID which are both asymmetric identities, and point out that the BFID is lightweight, economical, convenient, and green, and more suitable for the anti-counterfeit and source tracing of consumable merchandise such as food, drugs, and cosmetics. The authors design the structure of a united attestation platform for BFIDs and the composition of an identification system, and discuss the wide applications of BFIDs in public security and network security  antiterrorism and dynamic passwords for example.
