The Research Of Certificate Anti-counterfeiting System Based On Two-dimension Bar Code And Palmprint Recognition Technologies

TWo-dimension (2-D) bar code is a latest automated recognition technologydeveIoped from one-dimension (1-D) bar code, which is widely utiIized in manycountries. 2-D bar code technology is applied in the field of anti-counterfeiting,especiaIIy in certificate management, because its high secrecy and security.Furthermore, in order to ensure the certificate owner and carrier is the sameone, certificate anti-counterfeiting can integrate 2-D bar code technoIogy withbiometrics identification technoIogy.In this thesis, a system modeI of certificate anti-counterf6iting that integratedPDF417 bar code (2-D) with paImprint recognition technology is presented. AnexampIe of passport anti-counterf6iting system was buiIt. Much functionmodufes such as encoding and decoding PDF417 bar code, imagepreprocessing was incIuded. lt is a generaI system modeI that .can meet thespecific needs of other kinds of certificate by addin9 a IittIe changes.
