Two-dimensional Bar Code Encryption Technology In The Security System Of Inspection Reports Of Applied Research,

Two-dimension bar code is a latest automated recognition technology developed from one-dimension bar code, which is widely utilized in many countries. Two-dimension bar code technology is applied in the field of anti-counterfeiting, especially in report system management, because its high secrecy and security.In this thesis, a system model of report anti-counterfeiting that integrated PDF417 bar code Two-dimension with encryption technology is presented. An example of inspection report anti-counterfeiting system was built. Much function modules such as encoding and decoding PDF417 bar code, encrpytion tachniques was included. Firstly it realizes the process from the input data to the relevant PDF417C code. Secondly it completes the process of translating two-dimensional bar code to relevant information. Encryption technology is used in full process of it.It is a general system mode that can meet the specific needs of other kinds of report, certificate, document by adding a little changes.
