At present, the modal in the industry anti-plug-in mode of online game is to adopt the figure identifying code.The figure identifying code is widely used in the login and the registration of website; Can prevent the malice decryption; Brush ticket, forum pour water, and prevent that effectively certain hacker from carrying out continuous login attempt to a certain particular registered user with specific program Brute Force mode, are the modes of a lot of websites pass authentication.Online game figure proof procedure comprises: server sends the figure identifying code to client; The user imports corresponding character string according to the figure identifying code in client, and client is sent to server end with said character string and discerns, and server returns recognition result to client then.
The method that figure identifying code of the prior art generates is as shown in Figure 1, mainly may further comprise the steps:
Step 101: the generation background image, and the color of this background image is the gradual change of a kind of color to another kind of color in this background image;
Step 102: picked at random 4-6 character generates character string picture from character set, and then, the color of the character string picture of generation makes the close but human eye of the color of color and background image of character string picture to distinguish;
Step 103: utilize character string deformation method that character string picture is out of shape based on the Bezier curved surface;
Step 104: generate noise according to each character color in the transformed character string image and size, and this noise is added to around the corresponding character with corresponding color and size;
Step 105: background image and character picture are merged, thereby obtain the figure identifying code.
The generative process more complicated of the figure identifying code of prior art; And proof procedure needs the user that identifying code is imported fully, and what perhaps the player was fierce plays, and the interface of ejecting the figure identifying code suddenly lets the user import the character of being seen; Then game process is interrupted; And online game is real-time, in the time of user's input validation sign indicating number, plays and is still carrying out, and this is a kind of game experiencing of misery to the user; And some identifying code possibly let the user be difficult to identification, has then further prolonged the required time of verifying.Therefore existing figure identifying code method can be brought negative experience to the player, even can cause player's loss to a certain extent, and recreation is had negative effect.
Summary of the invention
The invention provides a kind of safe verification method, under the prerequisite that does not influence player experience, realize the plug-in strike of playing based on pictorial symbolization.
The embodiment of the invention provides a kind of safe verification method based on pictorial symbolization, and this method comprises the steps:
A, server are concentrated a picked at random m Chinese character from pre-configured Chinese character, from m the Chinese character of having chosen, randomly draw 1 then and duplicate, and obtain m+1 Chinese character altogether, preserve the position coordinates of identical Chinese character; M is a natural number;
B, server generate the graph data of character according to said m+1 Chinese character, and the graph data that obtains is sent to client;
C, client generate picture according to the graph data that receives, and are rendered in the recreation, and point out the player to select identical Chinese character, and selection result is sent to server;
D, server judge according to the position coordinates of the identical Chinese character of being preserved whether a pair of Chinese character that the player selects is identical Chinese character, if then through checking, otherwise not through checking.
Preferably, the span of said m is 3 to 10.
Preferably, step B is said to be sent to the graph data that obtains before the client, further comprises: take rotation and dilatation to operate to said graph data graph of a correspondence.
Preferably, step B is said is sent to client with the graph data that obtains and comprises: said graph data is compressed, and the graph data after will compressing is sent to client;
The said client of step C generates picture according to the graph data that receives and comprises: client receives the graph data after the compression, decompresses earlier, generates picture according to the graph data after decompressing again.
Can find out from above technical scheme; Employing is chosen identical Chinese character as verification mode from several Chinese characters; Corresponding figure identifying code generative process is comparatively simple, and for the player, changes existing input of character string into choosing mode; Simple to operate and be convenient to identification, can promote user experience.
