Below in conjunction with accompanying drawing, detailed Jie is carried out to auth method provided in an embodiment of the present invention, device, system Continue.

First embodiment

Referring to Fig. 6, it show a kind of flow chart of auth method of first embodiment of the invention offer.With reference to figure 2, the present embodiment describes the handling process of server, and the auth method that the present embodiment provides comprises the following steps：

Step S11, server receive the identifying code that user terminal is sent and pull request.

When the browser in user terminal 100 or the client monitors of various applications carry out the needs such as initiation transaction to user Verify the sensitive operation of identity or log in that certain number of applications is excessive within certain period or strange land log in certain application or When logging in situations such as certain applied cryptography input error number is excessive and occurring, it is possible to determine that authentication request is triggered, and user is whole End 100 can send identifying code to server 200 and pull request.

It for example, user terminal 100 can be to the server 200 being pre-configured with, such as can be a web page address, send Identifying code pulls request, to obtain identifying code.Specifically, identifying code, which is pulled in request, can carry page iden-tity (check Code), page iden-tity is used to identify a unique page, such as can be a numeral, page mark during each refresh page Knowledge can all change, and pulling request with identifying code has corresponding relation.

Step S12, the picture in picture database is randomly selected, feature enhancing element is added in the picture to be formed Feature strengthens picture, is strengthened by the feature in picture and cuts out an at least sub-pictures, the feature enhancing after being cut Picture forms identifying code background picture, and the region being cut in the identifying code background picture is formed and an at least subgraph Area of absence corresponding to piece.

Server 200, can be from authentication code database after the identifying code for receiving the transmission of user terminal 100 pulls request In randomly select an identifying code background picture and sub-pictures corresponding with selected identifying code background picture.

Storage has identifying code background picture and sub-pictures in authentication code database.Each identifying code background picture have with One or more sub-pictures corresponding to it, there is area of absence corresponding with sub-pictures in each identifying code background picture, when Sub-pictures, in the area of absence of identifying code background picture, may be constructed one according to precalculated position and the splicing of the predetermined anglec of rotation Individual complete picture.

It refer to Fig. 7, the generating process of identifying code background picture and sub-pictures may comprise steps of：

Step S101, choose the picture in picture database.

Picture database can establish in advance, be stored in server 200.In the embodiment of the present invention, identifying code background The particular content of picture need not have very strong classification identification, can directly use the figure of the contents such as landscape, animal, building Piece.Picture in picture database can be by server 200 directly by being captured on internet, and interconnection internet resource is very abundant, Therefore, the picture number of picture database easily reaches certain scale, and picture is artificially collected as broken so as to increase The difficulty of exam pool is solved, prevents from manually cracking.

In addition, the picture in picture database can also be the advertising pictures by being obtained on advertising pictures publisher server, Thus, when user according to precalculated position and the predetermined anglec of rotation splices sub-pictures the area of absence in identifying code background picture When, it can be seen that a complete advertising pictures, so as to carry out the service such as product promotion using identifying code.

Step S102, feature enhancing element is added in the picture to form feature enhancing picture.

The position of the sub-pictures cut in the picture selected is random, therefore, when larger area in picture being present The continuous view data with similar features region (such as sky, ocean, meadow) when, sub-pictures very maximum probability can be by Cut out in the region, because the details difference in the region is very small, even without, therefore user is located at the region in splicing Sub-pictures when be difficult to judge how to rotate sub-pictures and just can correctly be spliced by naked eyes.As shown in figure 8, due to Fig. 8 In presence larger area sky, therefore the region discrimination of two sub-pictures cut out by sky areas is very low, and And the element around two sub-pictures is also all approximate, user is difficult that sub-pictures are moved into correct area of absence, let alone is revolved Turn correct angle.Before being cut to picture, increase feature enhancing element in picture, thus it is possible to vary continuously have originally The discrimination in the region of the view data of similar features, make user be easier to distinguish area of absence corresponding to sub-pictures and The mode put, so as to improve the success rate of checking.

In the embodiment of the present invention, feature enhancing element can include one or more lines, and lines can be with For straight line, sinusoidal line, circular arc line etc..Feature enhancing element can also be other simple patterns, such as triangle pattern, circle Pattern, feature enhancing element can also be various watermark recoveries.It is understood that the present invention embodiment not with The specific manifestation form of feature enhancing element is limited.

Feature enhancing element can be plotted in the picture to form the feature enhancing picture at random, can also be incited somebody to action The picture that only drawing has feature enhancing element is synthesized in the picture to form the feature enhancing picture.Closed relative to picture Into method, feature is strengthened into element random being plotted in the mode of feature enhancing picture is formed in the picture and realize speed more It hurry up, do not interfere with the speed of identifying code background picture and sub-pictures generation substantially, nor influence the quality of original picture, Too big change will not also occur for the data volume of picture.

Further, the addition that feature enhancing element can be random can also be added in any region of the picture Continuously there is the region of the view data of similar features in the picture.

Further, the size of feature enhancing element and color can also be random, so can further increase certainly The difficulty that motivation cracks.

Fig. 9 is refer to, Fig. 9 is that the original picture in Fig. 8 increases the schematic diagram after Random line, as shown in figure 9, by scheming Continuously the random lines of region (sky) addition of the view data with similar features increase the discrimination in the region in piece, make Progress can be determined how according to the tendency of the lines in the lines in sub-pictures and identifying code background picture correctly by obtaining user Splicing.

Further, picture can also be strengthened the feature and carries out interference processing, such as strengthen picture in the feature Middle addition noise, the processing such as edge blurry is carried out, the sub-pictures of some interference splicings can also be increased, it is anti-to further enhance it Crack ability.

Step S103, strengthened by the feature in picture and cut out an at least sub-pictures, the feature after being cut Enhancing picture forms the identifying code background picture, and the identifying code is by cutting out an at least sub-pictures, quilt in the picture The picture after cutting forms the identifying code background picture, and the region being cut in the identifying code background picture forms institute State area of absence.

When cutting out multiple sub-pictures by feature enhancing picture, multiple described sub-pictures preferably have identical big Small and shape, it can so prevent machine from being cracked according to the size and shape of sub-pictures.

Cut picture can since the optional position that feature strengthens picture, the shape of cutting can include it is circular, square, Polygon etc. has the shape of multiple symmetry axis, does not allow so by machine or manually maliciously to crack.

Step S104, the sub-pictures cut out are carried out to the rotation of random angles, according to the angle calculation and institute rotated State the predetermined anglec of rotation corresponding to sub-pictures.

The rotation of the sub-pictures cut out progress random angles can further be increased and crack difficulty.With existing calculating Machine development level, it is relatively difficult directly to recognize the target location of picture and angle, cracks difficulty and optional area of absence Number a it is related to the anglec of rotation b of sub-pictures, crack difficulty=1/ (a！*b^a).Due to the position of cutting picture and angle all It is random, wants the position by artificially collecting identifying code background picture and sub-pictures and angle is used as that to crack exam pool be very Difficult, therefore there is very strong anti-crack ability.

The angle rotated according to sub-pictures can calculate the predetermined anglec of rotation corresponding with sub-pictures.Assuming that sub-pictures For circular picture, be rotated by 50 degree, only when its by opposite direction rotate 50 degree or rotate 310 degree again just can be by sub-pictures Correctly splicing is in identifying code background picture.That is, it is assumed that certain sub-pictures is rotated by x degree in generation, and it is predetermined The anglec of rotation can be that (- x ± n*360) degree or (360-x ± n*360) spend, wherein, n is natural number.

Step S105, preserve the identifying code background picture, postrotational sub-pictures, corresponding with the sub-pictures predetermined The anglec of rotation and precalculated position corresponding with the sub-pictures.

Wherein, precalculated position corresponding with the sub-pictures is area of absence corresponding with the sub-pictures in the checking Position in code background picture, or position of the area of absence corresponding with the sub-pictures in the identifying code background picture Between error within a predetermined range.Precalculated position corresponding with the sub-pictures, that is, the sub-pictures are in the identifying code Precalculated position in background picture, that is to say, that can be with precalculated position of the sub-pictures in the identifying code background picture Position consistency of the area of absence corresponding with the sub-pictures in the identifying code background picture or with the sub-pictures pair The position of error within a predetermined range between position of the area of absence answered in the identifying code background picture.

It should be noted that above-mentioned identifying code background picture and sub-pictures can be before step S11 the step of generation Perform, repeat step S101 to step S103 can generate some identifying code background pictures and corresponding sub-pictures.Above-mentioned step Suddenly can also be performed between step S11 and step S12, that is to say, that can be regenerated after receiving identifying code and pulling request Corresponding identifying code background picture and sub-pictures, embodiment of the invention are not limited thereto.

Step S13, the identifying code background picture and corresponding sub-pictures are handed down to the user terminal, so that institute State user terminal and the identifying code background picture and sub-pictures are showed into user.

Further, verification tip information can also be handed down to the user terminal 100 by the server 200, to Prompt user by sub-pictures by moving the area of absence with rotary splicing in the identifying code background picture.Certainly, the prompting Information can also be generated and shown by user terminal 100, and embodiment of the invention is not limited thereto.

Step S14, receive identifying code background that the user terminal returns, being spliced according to the instruction of the user The splicing result of picture and sub-pictures, according to the splicing result, judge the sub-pictures whether by according to precalculated position and The predetermined anglec of rotation splices the area of absence in the identifying code background picture, if it is, the result is by otherwise, testing Card result is not pass through.

If sub-pictures corresponding to the identifying code background picture issued only have one, the splicing result includes the son The actual position being spliced in the identifying code background picture of picture and the angle that each sub-pictures are rotated in splicing, Server 200 by compare be stored in the predetermined anglec of rotation corresponding with the sub-pictures in server 200 and with every height Precalculated position corresponding to picture, confirms whether the sub-pictures are tested according to precalculated position and the splicing of the predetermined anglec of rotation described Demonstrate,prove the area of absence of code background picture.It is spliced if the sub-pictures of the return of user terminal 100 are actual in identifying code Background Position in piece is identical with precalculated position corresponding to the sub-pictures, and the sub-pictures angle that is rotated and the son in splicing The predetermined anglec of rotation is identical corresponding to picture, then can be determined that the sub-pictures by according to precalculated position and the spelling of the predetermined anglec of rotation The area of absence of the identifying code background picture is connected on, is verified, otherwise, checking does not pass through.
