Embodiment
Below, describe the present invention by reference to the accompanying drawings.
Two-dimension code, be meant that the character information that will be encoded converts a string binary number bit stream to, this bit stream is divided into several numeric data code speech according to certain-length, the error correcting code speech that is used for playing error correction effect in the time of will decoding afterwards joins the numeric data code speech, form new bit stream, the two-dimension code of coding, and then formation again.Therefore, the sign indicating number figure that contains the two-dimension code of coded message comprises: be used for supplementary and numeric data code speech such as locating information that specified data sign indicating number lexeme puts, version information, so-called numeric data code speech is meant the bit stream with certain-length, in order to the character of presentation code.
In the prior art, during the two-dimension code coding, any character that is encoded all is evenly distributed on the whole sign indicating number figure, and therefore, if hide latent part sign indicating number figure, then two-dimension code can't be distinguished.
The embodiment of the invention is divided into show one's color code figure and concealed code figure with described two-dimension code code figure, and the described code figure that shows one's color is macroscopic code figure, and described concealed code figure is the sightless concealed code figure of naked eyes.
During the two-dimension code coding, needs are assigned to the code figure that shows one's color as yard numeric data code word of figure recognition of showing one's color partly arrange, need to be assigned to concealed code figure as the numeric data code word of concealed code figure recognition and partly arrange.Like this, yard figure two-dimension code of showing one's color can be distinguished, and stealthy sign indicating number figure two-dimension code also can be distinguished.
Wherein, show one's color code figure and concealed code figure can encode separately, and perhaps show one's color code figure and concealed code figure are as a whole Unified coding.Code figure and concealed code figure are used as again a whole Unified coding if show one's color, and then concealed code figure and yard two-dimension code integral body that figure forms of showing one's color can be read again.
Embodiment one
