The application is under the prerequisite of being convenient to user's identification, in order to reduce the computer recognition success rate of the character in the identifying code picture, a kind of supplying method, system and device of verification code information are provided, in the method, can the cutting of identifying code picture be at least two sub-pictures by server, character in described identifying code picture has at least a character to be split the part that can not identify this character at least two, each several part lays respectively in a different sub-pictures, and each sub-pictures after cutting is sent to client.All there is not character whole and complete in the identifying code picture in each sub-pictures that provides to client due to server in the embodiment of the present application, therefore very little of its possibility that is cracked and identify by computer, the fail safe that has effectively improved identifying code.Meanwhile, the user only need to can identify each sub-pictures combination the character in the identifying code picture, and is easy to use.
Below in conjunction with Figure of description, the embodiment of the present application is elaborated.
The verification code information that Fig. 1 provides for the embodiment of the present application the system configuration schematic diagram is provided, this system comprises: server 11 and client 12, wherein,
In the embodiment of the present application, every width identifying code picture comprises the information of corresponding identifying code, when server during in the request that receives client, identifying code picture cutting to be supplied is at least two sub-pictures, character in the identifying code picture has at least a character to be split the part that can not identify character at least two, each several part lays respectively in a different sub-pictures, and at least two sub-pictures after cutting are sent to described client.
Concrete, server is with the identifier cutting in this identifying code picture during for sub-pictures at least, can adopt figure cutting algorithm, at least one character cutting in this identifying code picture is at least two unrecognizable parts, these two parts lay respectively in different sub-pictures, when sub-pictures is made up, after these two unrecognizable partially overlapping, the user can identify the identifier that is split, and realizes in this way the identification of the identifying code in the sub-pictures after the user is to cutting.
The verification code information that Fig. 2 A provides for the embodiment of the present application process is provided, this process comprises the following steps:
S201: server with the cutting of identifying code picture at least two sub-pictures after, wherein the character in the identifying code picture has at least a character to be split the part that can not identify character at least two, each several part lays respectively in a different sub-pictures.
Server is when this identifying code picture of cutting, this identifying code picture cutting can be at least two sub-pictures, a part due to corresponding at least one character of each sub-pictures, when the quantity of the sub-pictures after cutting is more, when should a plurality of sub-pictures offering client, can reduce the possibility that these a plurality of sub-pictures are cracked, improve the success rate of this identifying code picture opposing machine recognition.
S202: the sub-pictures of server after with cutting is sent to client.
S203: the character information in the identifying code picture that identifies according to correspondence after described at least two sub-pictures combination that receives that described client provides.
Adopting figure cutting algorithm with this identifying code picture cutting during at least two sub-pictures, at least one character in the identifying code picture is split and is at least two unrecognizable parts, and unrecognizable part lays respectively in different sub-pictures.When this identifying code picture of cutting, can adopt the masking-out of black and white picture, the masking-out of this black and white picture is black-and-white two color, before this masking-out is placed in identifying code picture corresponding to identifying code, wherein the part of the corresponding white of this identifying code picture is a sub-pictures, and the part of the corresponding black of picture is another sub-pictures.
Fig. 2 B is depicted as the identifying code picture that character " BtK45 " is corresponding, adopts figure cutting algorithm, and cutting is 2 sub-pictures, and 2 sub-pictures can relatively move, and comprise respectively the part of at least one character, the picture of unrecognizable character.For example during identifying code picture cutting that character " BtK45 " is corresponding, in two sub-pictures after cutting, character t, K, 4,5 are discernible, it is unrecognizable only having character B, perhaps B, t are unrecognizable, but K, 4,5 is discernible, concrete cutting process can be set as required flexibly.For the ease of distinguishing, each sub-pictures after this cutting adopts a kind of color to identify, and for example the first sub-pictures adopts red sign, and the second sub-pictures adopts blue sign.
Because server in this application is at least two sub-pictures with this identifying code picture cutting, the part of corresponding at least one character of each sub-pictures, namely do not have the information of complete identifying code in each sub-pictures, and each sub-pictures can cutting be arbitrary shape.Therefore after at least two sub-pictures after this cutting are sent to client, machine is difficult to these at least two sub-pictures combinations are verified a yard picture, i.e. these at least two sub-pictures None-identified for machine, even in a certain process machine recognition one of them sub-pictures, but because the identifying code picture after this cutting comprises at least two sub-pictures, machine still can't crack the information of this identifying code.
in addition also due to server when the cutting identifying code picture, with this identifying code picture cutting at least two sub-pictures, and each to same identifying code picture cutting to obtain the possibility of same sub-image sheet very little, even therefore machine has been identified some sub-pictures in a certain process, and after server provides the sub-pictures after the cutting again, machine also knows this sub-pictures is to obtain after which identifying code picture cutting, namely do not know this sub-pictures concrete should be corresponding with which sub-pictures, just do not know how to make up with other sub-pictures yet, thereby also just can't get verification code information, thereby increased the reliability that verification code information provides.
Server with the cutting of identifying code picture at least two sub-pictures after, these at least two sub-pictures are offered client, in order to resist machine recognition, server can be arbitrary shape with these at least two sub-pictures cuttings, is perhaps a plurality of sub-pictures with this identifying code picture cutting.And when sending to client, can be with these at least two sub-pictures combination in any, these at least two sub-pictures can be fully overlapping, and perhaps apart from certain distance, and this distance can be arbitrary value.
After picture after client arrives these at least two sub-pictures combination in any, picture after this combination has been offered the user, this moment is because the picture after this combination comprises at least two sub-pictures after cutting, the part of corresponding at least one character of each sub-pictures, the picture None-identified for machine after therefore should making up.And for the user, the character information that it can comprise according to each sub-pictures adopts driving style to drag any one in these at least two sub-pictures, and these at least two sub-pictures are reconfigured.
Client to the combination after sub-pictures after, the operation of client records user to each sub-pictures, determine the motion track of relative other sub-pictures of sub-pictures of this operation, according to the motion track of determining, but the sub-pictures after movement is offered the user with the rear corresponding identifier of other sub-pictures combinations.Concrete according to the operation of user to each sub-pictures, when determining the motion track of relative other sub-pictures of this operated sub-pictures, can according to the user to the direction of the drag operation of each sub-pictures and the duration of drag operation, determine this trailing sub-pictures motion track of other sub-pictures relatively.
In addition, identify the speed of this verification code information in order to improve user in the embodiment of the present application, when the picture after server will make up offers client, can also provide corresponding information to client, this information can offer the user with the form of word, the form of picture or the form of animation, obtain the operation of this verification code information according to this sub-pictures with the prompting user, for example can be that the prompting user carry out the method for drag operation, concrete can be direction of dragging etc.
In the embodiment of the present application in order to improve the success rate of this verification code information opposing machine recognition, when at least two sub-pictures of server after with this cutting offer client, can with these at least two sub-pictures according to the rule stack of setting, the picture after stack be offered client.Two sub-pictures in Fig. 2 that Fig. 3 provides for the embodiment of the present application offer the picture of client after according to the rule stack of setting.
When overlaping fully due at least two sub-pictures, the identifier after the unrecognizable character that these at least two sub-pictures are corresponding makes up is discernible, is this verification code information.Therefore in the embodiment of the present application, regular according to setting, when determining the picture after sub-pictures corresponding to these at least two unrecognizable characters superposes, can determine arbitrarily the position when superposeing of every width sub-pictures, as long as the position in the time of can superposeing according to this, determine sub-pictures corresponding to these at least two unrecognizable characters and overlap when the identifier of composition can be identified afterwards, determine that the relation of the changes in coordinates of the unrecognizable character that at least two sub-pictures of motion track and this are corresponding gets final product.
Specifically for example, in the cutting of identifying code picture for two sub-pictures, wherein the size of each sub-pictures can be identical with the size of this identifying code picture, also can be different, but when these two sub-pictures overlaped fully, the identifier after the unrecognizable character that these two sub-pictures are corresponding makes up can be identified.Be moved to the left 20mm with this first sub-pictures in the position that overlaps fully this moment, the second sub-pictures 10mm that moves right in the position that overlaps fully superposes after two sub-pictures move, the picture after being superposeed, this picture is offered client, for user discrimination.
Due to respectively corresponding at least one unrecognizable character of these two sub-pictures, when only having these two sub-pictures to overlap fully, identifier after this at least one unrecognizable character combination just can be identified, therefore after these two sub-pictures being superposeed according to the setting rule, be about to these two sub-pictures and moved a segment distance to both direction respectively take the position that overlaps fully as benchmark, picture after two sub-pictures superpose, the identifier after these two unrecognizable characters combinations can be identified scarcely.
At least two sub-pictures after server is with this cutting, superpose and when offering client according to the rule of setting, need to determine what kind of changes in coordinates, can obtain verification code information by the sub-pictures after this stack, namely need to determine the motion track of the corresponding cursor of user, with the relation of each sub-pictures changes in coordinates, concrete can be according to the variation of the abscissa of motion track, with the changes in coordinates relation of each sub-pictures, determine the changes in coordinates of described at least two sub-pictures; Or, according to the variation of the ordinate of motion track, with the changes in coordinates relation of each sub-pictures, determine the changes in coordinates of described at least two sub-pictures; Or, according to the variable in distance of motion track, with the relation of the changes in coordinates of each sub-pictures, determine the changes in coordinates of described at least two sub-pictures.
This is because server is in order to provide discernible identifier to client, when needing to determine that cursor corresponding to user moves in the hot-zone, relation between the changes in coordinates of the picture that its motion track is corresponding with two unrecognizable characters, thereby can work as cursor movement corresponding to user when meeting some requirements, the identifier after two unrecognizable characters combinations after changing can be able to be identified.The wherein movement of cursor corresponding to this user movement that can be the user by its corresponding cursor of dragging the mouse mode and determining also can the drag operation of user on touch-screen be determined and the movement of corresponding cursor.
Concrete when the concerning of the changes in coordinates of determining the picture that each motion track of setting cursor corresponding to user corresponding to rule is corresponding with unrecognizable character, the variation of the abscissa of cursor movement that can be corresponding according to this user, determine the changes in coordinates of the picture that this unrecognizable character is corresponding, the variation of the ordinate of cursor movement that also can be corresponding according to the user, determine the changes in coordinates of the picture that this unrecognizable character is corresponding, the changes in coordinates of the picture that this unrecognizable character is corresponding is determined in the variation of the distance of also can the user corresponding cursor movement.
After server has been determined this corresponding rule, this corresponding rule can be offered client, the motion track of the cursor that the user who recognizes by client is corresponding, according to this motion track of determining, and the motion track that sends of the server that receives and the changes in coordinates relation of each sub-pictures, determine the changes in coordinates of this each sub-pictures.Perhaps in order further to resist machine recognition, this corresponding rule also can be kept at server side, recognize the motion track of cursor corresponding to user when client after, this motion track is sent to server, server is according to the motion track that receives, and the motion track of preserving and the changes in coordinates relation of each sub-pictures, determine the changes in coordinates of each sub-pictures.
Also describe with above-described embodiment, after picture after two sub-pictures are superposeed according to the rule of setting offers client, wherein stack the first sub-pictures of obtaining this picture has been moved to the left 20mm in the position that overlaps fully, the second sub-pictures 10mm that moved right in the position that overlaps fully.Be the variation of the abscissa of cursor movement corresponding to user when what preserve, during the concerning of the changes in coordinates of the sub-pictures corresponding with this unrecognizable character, can be that cursor corresponding to user is at the every increase of the abscissa of hot-zone (or reducing) 1mm, the first sub-pictures 4mm that moves right, the second sub-pictures is moved to the left 2mm, can determine to move in the hot-zone when cursor corresponding to user, when the variation of its abscissa met some requirements, the identifier that obtains after the unrecognizable character that these two sub-pictures are corresponding makes up was discernible.During this certain condition, when cursor corresponding to this user moves in the hot-zone, its abscissa changes and (has increased or reduced) 5mm, this moment the first sub-pictures 20mm that moved right, the second sub-pictures has been moved to the left 10mm, namely the first sub-pictures has moved to its front coincidence position that superposes, and the second sub-pictures has also moved to the coincidence position before its stack, and the identifier after therefore two unrecognizable characters corresponding to sub-pictures make up can be identified.
Above-described embodiment is the variation with the abscissa of cursor corresponding to user, the changes in coordinates of determining the picture that this unrecognizable character is corresponding is that example describes, variation when the ordinate of cursor corresponding to User, preserve the variation of ordinate corresponding to this unrecognizable character, during the changes in coordinates of the sub-pictures corresponding with this unrecognizable character, its process and said process are substantially similar, here just not explanation one by one.Be the variable in distance of cursor corresponding to user when what preserve, when the changes in coordinates of the sub-pictures corresponding with this unrecognizable character concerns, can be the distance of the movement of cursor corresponding to user in setting-up time length when satisfying condition, the coordinate of the first sub-pictures and the second sub-pictures be done corresponding variation.For example can be within 1ms, when the distance that cursor corresponding to user moves in the hot-zone is 1mm, this first sub-pictures 4mm that moves right, the second sub-pictures is moved to the left 2mm, can determine the distance that the mouse as the user moves in the hot-zone, when meeting some requirements, the identifier that obtains after unrecognizable character combination corresponding to these two sub-pictures is discernible, wherein the distance of this movement is the distance that is moved to the left, and can be also the distance that moves right.
concrete in order to reduce the success rate of machine recognition, can preserve in the embodiment of the present application a plurality of setting rules in server, and preserve each and set motion track corresponding to rule and the changes in coordinates relation of each sub-pictures, after cutting is at least two sub-pictures, can these at least two sub-pictures be superposeed according to corresponding setting rule, and in subsequent process, when having obtained the motion track of cursor corresponding to user in the hot-zone, can set motion track corresponding to rule and the changes in coordinates relation of each sub-pictures according to this, determine the coordinate after each sub-pictures changes.
Fig. 4 provides for the embodiment of the present application, after the changes in coordinates of these two sub-pictures, and the character schematic diagram in the identifying code picture that after these two sub-pictures combinations, correspondence identifies.
After the changes in coordinates relation of the motion track of having determined the cursor that the user the is corresponding sub-pictures corresponding with unrecognizable character, obtain the motion track in hot-zone corresponding to the picture of cursor corresponding to user after this stack, this hot-zone can for the zone at the picture place after this stack, can be also perhaps other zones corresponding to picture after this stack.
When server has obtained motion track in hot-zone corresponding to the picture of cursor after this stack corresponding to user, server is set motion track corresponding to rule and the changes in coordinates relation of sub-pictures according to this that preserve, determine the changes in coordinates of these at least two sub-pictures, and the character information in the identifying code picture that correspondences after the combination of at least two sub-pictures after changes in coordinates are identified offers client and is shown to the user.Motion track in hot-zone corresponding to picture when the cursor corresponding according to the user after this stack, identifier after unrecognizable character combination after these at least two sub-pictures changes in coordinates of determining is for till can identifying, and client has got identifying code corresponding to this discernible identifier.
server is when providing this identifying code in the embodiment of the present application, this identifying code picture cutting is at least two sub-pictures, and the character in the identifying code picture has at least a character to be split the part that can not identify character at least two, each several part lays respectively in a different sub-pictures, and the cutting of this sub-pictures without any rule, and can cutting be at least two sub-pictures, therefore very little of its possibility that is cracked, can effectively resist machine recognition, in addition due to the part of corresponding at least one character of each sub-pictures, even obtained each sub-pictures, also can not identify the particular content of this sub-pictures, therefore can effectively reduce the success rate of machine recognition, also be convenient to simultaneously user's identification, improve the efficient that the user identifies identifying code.
in addition also due to server when the cutting identifying code picture, with this identifying code picture cutting at least two sub-pictures, and each to same identifying code picture cutting to obtain the possibility of same sub-image sheet very little, even therefore machine has been identified some sub-pictures in a certain process, and after server provides the sub-pictures after the cutting again, machine also knows this sub-pictures is to obtain after which identifying code picture cutting, namely do not know this sub-pictures concrete should be corresponding with which sub-pictures, just do not know how to make up with other sub-pictures yet, thereby also just can't get verification code information, thereby increased the reliability that verification code information provides.
