Coded strings are converted into character string, for example, coded strings " 01000001010011100101110 " are converted into " 2UVWXYZ " word
Symbol string.It should be noted that under normal circumstances, for ensureing the information security hidden in safe Quick Response Code, typically making safety
In Quick Response Code, can be encrypted to each character string, therefore, before the content to character string parses, first will be to this word
Symbol string is decrypted, i.e. step 1005：Obtain cipher key.Because different coded strings correspond to different AESs, therefore,
Need the index finding encryption could decode.Step 1006, is decoded to character string after finding cipher key index.For example, right
Generating new character string after character string " 2UVWXYZ " deciphering is " 1ABCDEF " it is preferred that can be several in described character string
Word, letter, symbol or above several combination.Step 1007：Decompose third dimension information.Wherein said third dimension information refers to
It is stored in the character string on the free space of ordinary two dimensional code, or message identification.Normally, due to letter that character string is to be carried
Breath is more, so the character string after deciphering typically all can be very long.For example, described new character string " 1ABCDEF " is decomposed into
" 1 " and " ABCDEF ", concrete decomposition rule can designed, designed as needed.Step 1008：Understand every group of character string after decomposing
Implication, obtain third dimension text message.For example, in the present embodiment the implication that " ABCDEF " represents is " the industrial and commercial silver of China
OK ", " 1 " represents this bank's sequence number.User can by understanding third dimension text message out, that is, the Industrial and Commercial Bank of China with
