Abstract
There is provided a combined two-dimensional code generating apparatus, comprising: a two-dimensional code information generating module (), a key information generating module (), an abstract computing module (), a two-dimensional code coding module (), a two-dimensional code image generating module (), and a dot matrix image generating module (), wherein: the two-dimensional code information generating module is configured for generating data information to be coded into the two-dimensional code; the key information generating module is configured for generating a key for computing an abstract; the abstract computing module is configured for computing, using a Hash algorithm, the data information of the two-dimensional code and the abstract of the key; the two-dimensional code coding module is configured for combining the abstract information and the data information of the two-dimensional code into coding data of the two-dimensional code; the two-dimensional code image generating module is configured for coding the coding data of the two-dimensional code into the two-dimensional code to generate a two-dimensional code image. The dot matrix image generating module is configured for generating a corresponding dot matrix based on the key information, wherein the dot matrix is positioned by a positioning image of the two-dimensional code and generated outside or inside the two-dimensional code image, the bit error rate caused by the dot matrix being smaller than the error correction rate of the two-dimensional code.
