Embodiment
A kind of security code information generating method as shown in Figure 1 of the present invention, comprises the following steps：
Step 1: establishment value color table and picture library, described value color table be used to describing false proof numerical value, false proof numerical value color with It is worth the syntagmatic of color index numerical value three, picture library prestores several false proof pictures.
By a two-dimensional table, the combination of value and color can be described, the table is referred to as value color table, as shown in table 1.
Table 1. is worth color table
1 2 3 4 5 6 7 8 9
It is black 0 1 2 3 4 5 6 7 8
Orange 9 10 11 12 13 14 15 16 17
It is yellow 18 19 20 21 22 23 24 25 26
It is red 27 28 29 30 31 32 33 34 35
It is purple 36 37 38 39 40 41 42 43 44
It is blue 45 46 47 48 49 50 51 52 53
It is green 54 55 56 57 58 59 60 61 62
It is blue or green 63 64 65 66 67 68 69 70 71
The 1st false proof numerical value of behavior in table 1, the 1st is classified as false proof numerical value color, and other numerical value index numerical value for value color, such as 30 represent that the color that false proof numerical value is 4 and 4 is red.
Step 2: external system by parameter call start anti-counterfeiting information generating process, the parameter include ISN, Url and Prefix.System is false proof operation system, and ISN is the decimal value being pre-stored within false proof operation system in the present embodiment, from ISN can obtain all anti-counterfeiting information by algorithm.Url is website information, and prefix is self-defined, such as SC, is four valleies Abridge in area.
Step 3: Url, prefix and ISN are merged, and its check code is calculated, then by Url, prefix, ISN and verification Code character is closed, and forms Quick Response Code.
Before again merging Url, prefix and ISN, ISN is subjected to multi-system conversion first, multi-system is in each numerical digit Represent that number, such as A represent that 10, B represents 11 etc. using more character, code length can be effectively compressed.Enter when using 33 System, can only with 4 character cans represent it is maximum up to 1185920 decimal number.
For example, call parameters are respectively：
ISN：3267944；
Url：http://www.cdxdl.com/Id=；
Prefix：SC；
By decimal system code comversion it is 33 systems in this example, 33 ary codes 11113RXVM is obtained by ISN 3267944；
The algorithm of check code is：Prefix, multibit code are encrypted, ASCII value is then taken to encrypted result and is added, Finally pair and modulus and add 1.
Original character string：SC11113RXVM；
After encryption：268804160B380F41188BFE41448A8521, the computations process are counted using conventional encryption Calculation method, is no longer specifically described in this example；
ASCII and：1759；
To 9 modulus and 1 is added to obtain check code：5；Wherein 9 be the item number of false proof numerical value, is worth color table the first behavior 1-9, is 9 The false proof numerical value of item.
The two-dimentional digital content ultimately generated is：
http://www.cdxdl.com/Id=SC11113RXVM5.
Step 4: taking one group to specify place value from the Quick Response Code of step 3, calculated and by result of calculation by being worth color index Value color corresponding to obtaining after the item number modulus of numerical value is indexed to value color table intermediate value color respectively and indexes numerical value, the according to value color in color table is worth Index scans for, and obtains indexing the corresponding false proof numerical value of numerical value and false proof numerical value color with value color, according to false proof numerical value and False proof numerical value color forms the false proof numerical information list with color data.
Calculating is encrypted from the character string of the prefix of the Quick Response Code of step 3, ISN and check code composition, then from this From i-th, i+j in character string1-1、...、i+jn-1Position, common n positions take ASCII value to carry out ASCII calculating respectively, and result of calculation is to value Color indexes the item number modulus of numerical value, respectively obtains n value color index numerical value；Wherein, i is from character string integer-bit character from left to right, j For integer bit interval.
Specifically, i-th bit manipulative indexing value is calculated as taking the i-th, ASCII value of i+1, i+2 position respectively；
According to (i-th bit ASCII value * 1)+(i+1 bit ASCII value * 2)+(i+1 bit ASCII value * 3)+1, obtain ASCII value summation；
Item number modulus by above-mentioned ASCII value summation to value color index numerical value, obtains index value corresponding to i-th bit；
According to above-mentioned computational methods, remaining n-1 value color index numerical value is calculated successively.
In this example：
Prefix, multibit code and check code are encrypted, then from encrypted characters string respectively from 34,36,38,40, 42 start to take ASCII value to be calculated, and obtain value color index list.
Original character string：SC11113RXVM5；
After encryption：
2B174C09F56606D9963F6163FBBE8C23FC17CF01C6F49A333757ABB2AF8BE0CA31C4492FD5F1B 08；
Take ASCII (so that first value color indexes as an example)：34-36 positions are respectively 67,49,55
ASCII is added (so that first is worth color index as an example)：67*1+49*2+55*3+1=331；
To 72 modulus (so that first is worth color index as an example)：43 (72 index numerical value item number amount for value color table intermediate value color)
The five value colors index numerical value finally obtained is respectively 43,17,2,67,51.
By obtained value color index numerical value index value color table 1, value color index list as shown in table 2 is established.
Table 2. is worth color index list
According to value color index list, false proof numerical information list as shown in Figure 2 is obtained.
Step 5: from the Quick Response Code of step 3, calculated by picture indices and by result of calculation to false proof in picture library Picture sum modulus, obtains picture indices, and corresponding false proof picture is then obtained from picture library.
The process that picture indices calculate includes the character string for forming the prefix of the Quick Response Code of step 3, ISN and check code Calculating is encrypted, the ASCII of the character string after being encrypted and, modulus then is carried out to picture sum, obtains described figure Piece indexes.
In this example：
Original character string：SC11113RXVM5；
After encryption：268804160B380F41B81B1609F06ED677
ASCII and：1777；
To 6 modulus：1 (6 be picture sum)；
1 is the 1st pictures as shown in Figure 3.
Step 6: false proof numerical information list and step 5 that the Quick Response Code that step 3 is formed, step 4 are formed obtain False proof picture combination producing security code information, as shown in Figure 4.
The character string id information that the security code information of generation also includes prefix and ISN forms.
