Abstract
There is provided a combined two-dimensional code generating apparatus, comprising: a two-dimensional code information generating module (1), a key information generating module (3), an abstract computing module (4), a two-dimensional code coding module (5), a two-dimensional code image generating module (6), and a dot matrix image generating module (7), 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 config…
