The uniqueness that the signing messages in signing messages and the obtained two dimensional code of decryption in equipment has, can fast and accurately sentence
It is both disconnected whether consistent, i.e., whether meet veritification condition.
Finally, the structure based on judgement, result is presented, if signature comparison is consistent, content is shown；If signature
It compares inconsistent, does not show content.
Specifically, during result is presented, can be other various can show two kinds or three kinds state differences
Presentation mode, such as two kinds can be " consistent " or " inconsistent ", three kinds can be " consistent ", " inconsistent ", engineering noise.
Whether the present invention unanimously determines according to the signature in the signature and two dimensional code in last equipment for customizing, it is assumed that is directed to
The equipment for customizing of A unit exploitation, is modified signature, then the parsing result of the two dimensional code of all A production of units is just with equipment
On signature it is inconsistent, then information can not be shown.Assuming that B unit is want to produce two dimensional code with the signature of A unit, but B does not have A
Unsymmetrical key, then B unit generate two dimensional code cannot be parsed by equipment institute's barcode scanning of A.If the key that B oneself is generated
The two dimensional code for falsely using A signature is generated, then B must possess a full set of two dimensional code rendering technique of A.So if this two dimensional code
Rendering technique is underground, then process of the invention will be possible to ensure that the authentic and valid of information source.
