Embodiment
Below with reference to accompanying drawings exemplary embodiment of the present disclosure is described in more detail.Although show exemplary embodiment of the present disclosure in accompanying drawing, however should be appreciated that can realize the disclosure in a variety of manners and not should limit by the embodiment set forth here.On the contrary, provide these embodiments to be in order to more thoroughly the disclosure can be understood, and complete for the scope of the present disclosure can be conveyed to those skilled in the art.
As shown in Figure 1, provide a kind of picture validation code verification method in one embodiment of the present of invention, it comprises:
Step 110, selects picture from the picture library preset, and generates identifying code according to picture, the variable morphology of identifying code, and identifying code forms picture under specific modality.In the present embodiment, for how generating identifying code do not limit, such as, picture can be cut into the identifying code of jigsaw puzzle fashion, the block number of wherein picture mosaic does not also limit.
Step 120, receives the verification operation of user, and changes the form of identifying code according to verification operation.Such as, based on aforesaid jigsaw puzzle fashion identifying code, the verification operation of user is the concatenation to identifying code.
Step 130, selects first area from amended identifying code and extracts the image information of first area.
Step 140, from picture, select second area and extract the image information of second area, the position of second area on picture is corresponding with the position of first area on identifying code.In the present embodiment, if user rs authentication operation is correct, then on identifying code, the image information of first area and the image information of second area on picture must be identical.
Step 150, compares the image information of first area and the image information of second area, judges that whether the verification operation of user is successful according to result.According to the technical scheme of the present embodiment, when will compare identifying code and picture, not that all images information of identifying code and picture is compared, but the image of the corresponding subregion of extracting position compares, because the image information extracted tails off, so just uprise for the relative efficiency of extracted image information, thus can judge whether fast to be proved to be successful.
As shown in Figure 2, provide a kind of picture validation code verification method in one embodiment of the present of invention, it comprises:
Step 210, obtains the exterior artwork outside picture library, upgrades the picture in picture library.In the present embodiment, by upgrading the picture in picture library, the identifying code generated can be made to continue to change, thus the verification mode of identifying code can not be collected completely, avoids and is verified by enumerating mode by machine.
Particularly, can according to the application using identifying code, the webpage that selective gist is corresponding also obtains exterior artwork from webpage.Such as, this identifying code is used in Mobile phone game, then extract picture from the official Internet page of these mobile phone games and add in picture library, this can strengthen the relevance between identifying code and application, make identifying code more easily understand by the user of this application of use.
Further, the picture of the difference of issuing time and current time in predetermined threshold value can be selected from webpage as exterior artwork.Such as, can select and the picture of current time difference in one week; By the technical scheme of the present embodiment, can ensure that the picture obtained is newer picture, generate identifying code by newer picture and be not easy by machine recognition.
Step 220, selects picture from the picture library preset, from the multiple mode for generating identifying code preset, select generating mode, and generates identifying code according to selected generating mode, the variable morphology of identifying code, and identifying code forms picture under specific modality.In the present embodiment, for same picture library picture, can generate multiple identifying code by different generating modes, the technical scheme of visible the present embodiment is conducive to the kind enriching identifying code, and the difficulty that cracks of identifying code is strengthened.
Step 230, receives the verification operation of user, and changes the form of identifying code according to verification operation.
Step 240, selects first area from amended identifying code and extracts the image information of first area.
Step 250, from picture, select second area and extract the image information of second area, the position of second area on picture is corresponding with the position of first area on identifying code.
Step 260, after carrying out equal extent noise reduction, then extracts colouring information and compares first area and second area.In the technical scheme of the present embodiment, after the noise reduction carrying out certain degree, the middle colour of first area and second area can be eliminated, and only remains black and white, and the colouring information now extracted can be less, is more prone to compare.
As shown in Figure 3, provide a kind of picture validation code verification method in one embodiment of the present of invention, it comprises:
Step 310, selects picture from the picture library preset, and generates identifying code according to picture, the variable morphology of identifying code, and identifying code forms picture under specific modality.Identifying code comprises multiple part, and at least one part in multiple part can be moved.
Step 320, receives the verification operation of user, and changes the form of identifying code according to verification operation.
Step 330, selects first area from amended identifying code and extracts the image information of first area.
Step 340, according to the position that user carries out at least one moveable part after verification operation in identifying code, determines identifying code selected the position of first area and select.In the technical scheme of the present embodiment, if identifying code is different from picture, so the position of at least one moveable part of identifying code is incorrect, so can choose first area based on the position of this moveable part on identifying code.Such as, in the picture validation code shown in Fig. 4,410 is moveable part, and the position of dotted line wire frame is the tram of moveable part 410, then according to the technical scheme of embodiment own, selected first area can be dash area 420.
Or, according to the position of at least one moveable part during identifying code formation picture, determine identifying code selected the position of first area and select.In like manner, based on aforesaid content, also first area can be chosen according to the tram of this moveable part, if identifying code mistake, this moveable part must not be positioned on tram, the colouring information in this region is inevitable different from the colouring information of picture correspondence position, composition graphs 4, then the first area chosen can be dash area 430.
Step 350, compares the image information of first area and the image information of second area, judges that whether the verification operation of user is successful according to result.
As shown in Figure 5, provide a kind of picture validation code demo plant in one embodiment of the present of invention, it comprises:
Identifying code generation module 510, selects picture from the picture library preset, and generates identifying code according to picture, the variable morphology of identifying code, and identifying code forms picture under specific modality.In the present embodiment, for how generating identifying code do not limit, such as, picture can be cut into the identifying code of jigsaw puzzle fashion, the block number of wherein picture mosaic does not also limit.
Verification operation module 520, receives the verification operation of user, and changes the form of identifying code according to verification operation.Such as, based on aforesaid jigsaw puzzle fashion identifying code, the verification operation of user is the concatenation to identifying code.
First area extraction module 530, selects first area from amended identifying code and extracts the image information of first area.
