The application of digital signature Technology and fingerprint identification in 2D barcode person identity

Two-dimensional bar code as a kind of technology used in storage systems, and continuously as confidentiality carrier of identity information used in certificates. To enhance The authenticity of Two-dimensional bar code certificates and the effective verification to the authenticity of the users, paper proposes the reference model program combined with digital signature technology and fingerprint recognition technology, to ensure the High security and the uniqueness of biometric authentication of certificates in cryptography Sense, Effectively solutes the problem such as Anti-tamper, Anti-counterfeiting, prevent theft. The program applies to important meeting, reuse facilities, or other authentication.
