  Fraud (swindling money, property, or authority by fictionizing,
counterfeiting, forging, or imitating things, or by feigning other persons
privately) 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
converting symmetric identities (e.g., fingerprints) to asymmetric identities.
Make a comparison between a symmetric identity and an asymmetric identity, and
emphasize that symmetric identities cannot guard against inside jobs. Compare
asymmetric RFIDs with BFIDs, and point out that a BFID is lightweight,
economical, convenient, and environmentalistic, and more suitable for the
anti-counterfeiting and source tracing of consumable merchandise such as foods,
drugs, and cosmetics. The authors design the structure of a united verification
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.
