Here will be described exemplary embodiment in detail, its sample table shows in the accompanying drawings.When description below relates to accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawing represents same or analogous key element.Embodiment described in following exemplary embodiment does not represent all embodiments consistent with the application.On the contrary, they only with as in appended claims describe in detail, the example of apparatus and method that some aspects of the application are consistent.

In order to complete understanding the application, refer to numerous concrete details in the following detailed description, but it should be appreciated by those skilled in the art that the application can realize without the need to these details.In other embodiments, be not described in detail known method, process, assembly and circuit, in order to avoid unnecessarily cause embodiment fuzzy.

Before enforcement the application, set up abacus picture library in advance, abacus picture library should comprise the bead shelves picture group representing integer 0 to 9, the corresponding one group of bead shelves picture of each integer.Wherein, with one grade of bead in bead shelves finger counting dish, comprise bead, single lever and one section of beam, according to the table counting method of traditional abacus, every bead (upper pearl) on beam represents several 5, and every the bead (lower pearl) under beam represents several 1, two beads on usual beam, lower five beads of beam, represent integer 0 to 9 by the combination of upper pearl and lower pearl diverse location.Described bead shelves picture comprises bead, lever and one section of beam, can also comprise a part of upper side frame and lower frame.Fig. 1 is bead shelves picture exemplary plot, in Fig. 1, from left to right, the bead shelves picture of integer 0, integer 5 and integer 9 is represented respectively, by that analogy, every tensor calculus pearl shelves picture comprises bead, lever, one section of beam, a part of upper side frame and a part of lower frame to the form of other bead shelves pictures.

Abacus picture library can also comprise radix point picture group and abacus frame picture group, and abacus frame picture group can be divided into left frame picture group and left frame picture group.Picture in every picture group sheet can have different colors, texture etc., picture can have different width simultaneously, but breadth extreme is no more than certain limit value, such as, desirably the identifying code picture of interface or web displaying length and wish that the content of identifying code picture of display determines the limit value of each picture breadth extreme.Such as, often group has n picture, and abacus picture library can be expressed as follows in the matrix form:

Left frame: [L1, L2, L3......Ln];

Integer 0:[N01, N02, N03......N0n];

Integer 1:[N11, N12, N13......N1n];

Integer 2:[N21, N22, N23......N2n];

Integer 3:[N31, N32, N33......N3n];

Integer 4:[N41, N42, N43......N4n];

Integer 5:[N51, N52, N53......N5n];

Integer 6:[N61, N62, N63......N6n];

Integer 7:[N71, N72, N73......N7n];

Integer 8:[N81, N82, N83......N8n];

Integer 9:[N91, N92, N93......N9n];

Left frame: [R1, R2, R3......Rn];

Radix point: [D1, D2, D3......Dn].

Wherein, the alphanumeric in square bracket is the label of each picture, such as N81, and represent the tensor calculus pearl shelves picture in the bead shelves picture group corresponding to numeral 8, by that analogy, label also can adopt other forms to represent.The number of every picture group sheet also can be unequal.In every picture group sheet, last of picture label does not specify the order of picture, only for distinguishing other pictures in identical group.When certain picture of needs, according to the corresponding picture group of content search that picture represents, then can picture from picture group needed for random selecting, such as, when needing to represent the picture of integer 0, in the bead shelves picture group of integer 0 correspondence random selecting one of them.Complete abacus then can be regarded as the combination of left frame+bead shelves+left frame, and bead shelves part is in order to representative digit.Increase each quantity of picture group sheet and the complexity of picture in abacus picture library, make that the possibility of the identifying code picture of generation is more, picture complexity is higher, the difficulty of being cracked property can be improved.

In the first aspect of the application, provide a kind of identifying code Picture Generation Method.Fig. 2 is the schematic flow sheet of a kind of identifying code Picture Generation Method shown in the application one exemplary embodiment.After setting up abacus picture library in advance, as shown in Figure 2, described method comprises:

In step s 201, the numeral of a preset length is generated;

Wherein, described preset length is according to the length of interface or web displaying identifying code picture region, and wish that the numerical digit number of display is determined, and the length when bead shelves picture of the numeral correspondence of preset length is seamless spliced is less than the length of display identifying code picture region.The width of bead shelves picture limits when setting up abacus picture library in advance, and such as, wish display three or five numerals, then in abacus picture library, the breadth extreme of bead shelves picture is not more than 1/3 or 1/5 of the length of display identifying code picture region.If wish to show complete abacus pattern, i.e. the pattern of left frame+bead shelves+left frame, then after deducting the breadth extreme of left frame picture and left frame picture in abacus picture library in the length of display identifying code picture region, then determine the preset length of numeral.The numeral of preset length can stochastic generation, the numeral that also can recycle in ordered series of numbers carries out combining to generate, and such as, the numeral recycled in Fibonacci sequence carries out combining to generate, the multiplicity of the numeral of the preset length generated is fewer, and the security of identifying code is higher.

The digit length that preset length also can desirably show and abacus pattern are determined, the width of maximum picture in the digit length then desirably shown, abacus pattern and abacus picture library, show the length of identifying code picture region in design interface or webpage.Described preset length does not comprise radix point.

In step S202, obtain the numerical value of each numerical digit of described numeral;

Wherein, the numerical digit of numeral, namely individual position, ten, hundred, kilobit etc., when numeral is decimal, also comprise decimal place, namely 1/10th, one of percentage position etc.The numerical value of each numerical digit can use conventional computing method to obtain, such as, and numeral 4321: the numerical value of kilobit is 4321/1000 to round, and result is 4; The numerical value of hundred rounds for (4321-4*1000)/100, and result is 3, by that analogy.When the numeral of stochastic generation is decimal, the numerical computation method of each numerical digit of fraction part and said method are roughly the same, such as numeral 4321.12, then the numerical value of 1/10th is that 0.12*10 rounds, result is 1, the numerical value of one of percentage position rounds for (0.12-1*0.1) * 100, and result is 2.

In step S203, in the abacus picture library set up in advance, choose corresponding bead shelves picture respectively according to the numerical value of each numerical digit, the numerical value in described bead shelves picture represented by bead is corresponding with the numerical value of numerical digit;

Wherein, numerical value in bead shelves picture represented by bead is corresponding with the numerical value of numerical digit, can for the data value maps by the numerical value in bead shelves picture represented by bead and numerical digit, the such as mapping table of the numerical value of the numerical value of structure represented by bead and numerical digit, after the numerical value obtaining each numerical digit, according to the numerical value that bead in the bead shelves picture that mapping table finds the numerical value of each numerical digit corresponding should indicate, such as use displacement maps table, when the numerical value of numerical digit is 3, the corresponding numerical value represented is the bead shelves picture of 4, when the numerical value of numerical digit is 4, the corresponding numerical value represented is the bead shelves picture of 4, by that analogy, described mapping table also can be the mapping table of other Function Mapping relations.Use mapping table by the numerical value of the numerical value in bead shelves picture represented by bead and numerical digit to time corresponding identifying code due to user's input inputs according to the content shown in identifying code picture, therefore needs correspondingly to carry out reflection to the numeral of user's input when the identifying code inputted user is verified and penetrate.Numerical value in bead shelves picture represented by bead is corresponding with the numerical value of numerical digit, the numerical value be preferably in bead shelves picture represented by bead is equal with the numerical value of numerical digit, thus mapping can be saved and reflect the link of penetrating, improve identifying code to generate and verification efficiency, in the embodiment of the present application, principle and the enforcement of the application is set forth under this optimal way, other corresponded manners do not affect the principle of the application, and easily can be released the enforcement of the application under other corresponded manners by the implementation of class of the application under this optimal way.

After the numerical value obtaining each numerical digit, in abacus picture library, corresponding bead shelves picture group is found according to described numerical value, then in bead shelves picture group, one of them is chosen, such as, the numerical value of kilobit is 4, in abacus picture library, then find the bead shelves picture group of integer 4, then in the bead shelves picture group of integer 4, choose one.Described choosing can be random selecting, also can for choose successively by the storage order of bead shelves picture, such as, in the bead shelves picture group of integer 4, label sequential storage pressed by picture, and the front picture once chosen is N45, then choose picture N46 when secondary, after a picture group sheet has been chosen successively, from this group, storage order has been that the picture of first restarts to choose successively.

In step S204, bead shelves picture arranged by preset order and splices, generating identifying code picture.

Wherein, the bead shelves picture that the numerical value of each numerical digit is corresponding arranges choosing the bead shelves picture obtained by preset order, and is stitched together, then can generate identifying code picture after choosing.Described by preset order arrangement, in a kind of possible embodiment, the numerical digit order from big to small corresponding by bead shelves picture from left to right arranges, such as, numeral is 4321, then by kilobit, hundred, ten, bead shelves picture corresponding for the numerical value of each numerical digit from left to right arranges by the order of individual position, namely the order of bead shelves picture arrangement is: the bead shelves picture of 4 correspondences, the bead shelves picture of 3 correspondences, the bead shelves picture of 2 correspondences, the bead shelves picture of 1 correspondence, as shown in example in Fig. 3.

In the embodiment that another kind is possible, the numerical digit order from big to small corresponding by bead shelves picture arranges from right to left, such as, numeral is 4321, then by kilobit, hundred, ten, bead shelves picture corresponding for the numerical value of each numerical digit arranges by the order of individual position from right to left, namely the order of bead shelves picture arrangement is: the bead shelves picture of 1 correspondence, the bead shelves picture of 2 correspondences, the bead shelves picture of 3 correspondences, the bead shelves picture of 4 correspondences, as shown in example in Fig. 4.In this embodiment, the order of bead shelves picture arrangement is contrary with putting in order of numerical digit numerical value each in numeral, correspondingly, at the near zone of identifying code picture viewing area, or the region near identifying code input frame inputs the numeral contrary with each value arrangements order represented by identifying code picture with text prompt user.Due to the numeral that user is inputted verify time, the numeral of input and the numeral of stochastic generation to be compared and are verified by time, and the numeral of identifying code picture display is numerically sequentially contrary in numerical digit with the numeral of stochastic generation, therefore utilize described verification code information to log in after can preventing robot software from passing through to obtain the verification code information in identifying code picture further, increase the security of website in account and login management.

After being arranged by preset order by bead shelves picture, splice described bead shelves picture, generate identifying code picture.Described splicing can use conventional picture joining method, preferably seamless spliced, the described seamless spliced back gauge for removing in picture.

In above-mentioned steps S203, when the numeral of stochastic generation is decimal (non-integer), be also included in random selecting radix point picture in the abacus picture library set up in advance.Correspondingly, when the numeral of stochastic generation is decimal (non-integer), in above-mentioned steps S204, after bead shelves picture is arranged by preset order, also comprise the position according to radix point in described numeral, radix point picture is inserted in position corresponding between the bead shelves picture by preset order arrangement, and is spliced by the bead shelves picture of radix point picture and adjacent both sides.For radix point picture, described position corresponding between the bead shelves picture by preset order arrangement, can determine according to the number of the numerical digit of the numerical value of radix point both sides and both sides, such as, numeral is 4321.12, then between bead shelves picture radix point picture being inserted into two integers 1, numeral is 222.22, when can not judge the position of radix point according to the numerical value of radix point both sides, according to the number of radix point both sides numerical digit in numeral, namely three, left side numerical digit and two, the right numerical digit judge, now, if bead shelves picture from left to right arranges by the numerical digit order from big to small of correspondence, then with three, left side bead shelves picture and the position of the Rule of judgment determination radix point picture of two the bead shelves pictures in the right, if bead shelves picture arranges from right to left by the numerical digit order from big to small of correspondence, then correspondingly with three, the right bead shelves picture and the position of the Rule of judgment determination radix point picture of two the bead shelves pictures in the left side, numeral is symmetrical state, as 333.333, then in like manner can determine the position of radix point picture according to the number of radix point both sides numerical digit in numeral.

After determining the position that radix point picture is corresponding between the bead shelves picture arranged by preset order, radix point picture is inserted the position of described correspondence, and spliced by the bead shelves picture of radix point picture and adjacent both sides, described splicing is preferably seamless spliced.

Fig. 5 is the schematic flow sheet of a kind of identifying code Picture Generation Method shown in the application one exemplary embodiment.After setting up abacus picture library in advance, as shown in Figure 5, described method comprises:

In step S501, generate the numeral of a preset length;
