Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment the present invention is further described in more detail.
Fig. 1 is a kind of flow chart of identifying code processing method of the present invention, referring to Fig. 1, at identifying code of the present invention
Reason method specifically includes that
Step 101, generate at random two groups of identifying codes, one group as true identifying code, another group as interference identifying code.
Described identifying code is typically a string character string.In one embodiment, two groups of identifying codes of described random generation are permissible
It is the arbitrarily random two groups of identifying codes generating.
In order to increase the difficulty of identifying code further, in a further preferred embodiment, described random generate two groups test
Card code, can specifically include following steps 111 to 113:
Step 111, using predetermined key (key) generate ciphertext.Described key can be pre-set.
More specifically, this step 111 can obtain active user's (being currently needed for carrying out the user of identifying code checking)
Ip address and browser type, by described ip address, browser type and described predetermined set of keys composite characters string, then through plus
Close algorithm, such as Message Digest Algorithm 5 (md5, message-digest algorithm 5) algorithm, carries out irreversible
Encryption, generates a string ciphertext, such as similar to one section of ciphertext so follow-up:
d725ec04c205e27363daa4fda1f1d5b1.
Step 112, the corresponding grade of difficulty of this active user is determined according to the access characteristic information of active user.Described difficulty
Degree grade can also be pre-set, for example, can define three different grade of difficulty in a kind of specific embodiment, each
Grade of difficulty all corresponds to a labelling, for representing its grade difficulty.
During user's request internet, applications resource all can by user's history access information, for example user access time, ip,
The information such as browser type, are stored in the data base of service provider, and the present invention can be from the data base of service provider
Extract the history access information of active user, often all can go to compare with the history access information of this user upon request by a user, enter
Row grade of difficulty judges.The present invention can be set and be stored to the division scope of grade of difficulty in advance, such as ip ground
Location scope can divide different grades, and the ip address realm being included into highest blacklist can correspond to highest grade of difficulty, example
Spend grade 3 as difficult herein, the ip address realm of secondary one-level blacklist can correspond to grade of difficulty 2, and other ip address realms are then right
Answer the grade that difficulty is minimum, i.e. grade of difficulty 1.For example analysis can be made to the type of browser according to history access information again
And division, then corresponding for the commonly used browser type of some malicious robot program or unconventional browser type
Grade of difficulty is higher.For example ip address same to user can access the frequency of network application and carry out statistical analysiss again, if with
One ip address accesses consolidated network application with a high speed frequently (accessing interval especially little, for example, be spaced and be less than 1 second), then assert it
For malicious access, corresponding grade of difficulty is higher, can set the corresponding difficulty of different access interval of same ip address
Grade.
For example this step 112 can specifically include:
Obtain ip address and/or the browser type of active user；
Asking according to predetermined different grade of difficulty corresponding ip address realm, browser type and/or identical ip address
Ask interval, judge the grade of difficulty corresponding to the ip address of active user and/or browser type；
This grade of difficulty is defined as the corresponding grade of difficulty of this active user.
For example specifically may is that the corresponding grade of difficulty of ip address realm residing for ip address judging active user；Sentence
Determine the corresponding grade of difficulty of browser type of active user；And judge that last access the in active user ip address is visited with this
The time interval asked, determines corresponding grade of difficulty according to time interval；Finally will be highest true in these three grade of difficulty
It is set to the corresponding grade of difficulty of this active user.
Step 113, grade of difficulty determined by basis, obtain two groups of character strings as checking from described ciphertext at random
Code, wherein grade of difficulty is higher, and the character string of identifying code is more complicated.
For example, just can determine corresponding identifying code according to predetermined setting after reserving grade of difficulty, the following is a kind of 3
Individual grade of difficulty specific example:
Grade of difficulty 1, then obtain 2 groups of 4 cardinar numbers as two groups of identifying codes in aforesaid ciphertext at random；
Grade of difficulty 2, then obtain 2 groups 5 pure letters as two groups of identifying codes in aforesaid ciphertext at random；
Grade of difficulty 3, then the character string that random 2 group of 6 bit digital letter of acquisition mixes in aforesaid ciphertext is as two groups
Identifying code.
In described two groups of identifying codes, can at random using one group therein as true identifying code, test as interference for another group
Card code, for playing the effect obscured, increases the difficulty of robot program's identification.
Step 102, generation identifying code picture, including true identifying code and interference identifying code, described identifying code picture
In background in addition to identifying code be transparent background.
In this step 102, described generation identifying code picture, specifically include: correspond to generation one for described each group of identifying code
Open identifying code picture, in described identifying code picture, the background in addition to identifying code is transparent background.
More specifically, can respectively true identifying code and interference identifying code be utilized using font in fontlib at random
Color word color (being herein for example white) is horizontally-arranged one by one to be put, and the position up and down of each character can also be through row 10-20
Random floating between pixel, allows machine be difficult to catch real character position, produces the identifying code picture of two transparent backgrounds.
The color of described identifying code needs consistent with the background colour of the subsequent authentication page.
A kind of schematic diagram as the identifying code picture that Fig. 2 is generated by the present invention.Wherein " s t n t s n0 01 " is
Interference card code code, " s t n t s n 002 " is true identifying code, and the color of identifying code is white, goes out in identifying code picture
Background outside identifying code is transparent background, this in figure in order to make reader see the identifying code of white, special with gray background Lai
Represent transparent background, actually transparent background.
Certainly, in order to increase the difficulty of robot program's automatic identification identifying code further, the present invention's is a kind of further
Preferred embodiment in, can also described generation identifying code picture after, described identifying code picture is carried out hollow processing it
Before, further include: distortion effects process is carried out to the identifying code in described identifying code picture.
Described distortion effects process is carried out to the identifying code in described identifying code picture, specifically include:
Create one with identifying code picture equivalently-sized new painting canvas, former identifying code picture in the way of individual element
Each pixel is copied on this painting canvas, SIN function f (x)=sin (a*2 is passed through in the pixel position on this new painting canvas
π * y/height) the y-axis coordinate of pixel is processed, in formula, f (x) is the y-axis coordinate of the pixel on new painting canvas, y
For the y-axis coordinate of the same pixel point of former identifying code picture, height is the height of former identifying code picture.Drawn by this formula
The coordinate in pixel y week on new picture, x-axis coordinate and artwork are consistent, and may finally obtain a sine curve the same
Waveform distortion identifying code, by the numerical value of adjusting parameter a, the degree of distortion can be changed, can be according to reality
Situation is adjusted to a suitable value.In an advantageous embodiment, can be respectively to real character code and invalid character
Code all carries out distortion process.
By above-mentioned process it is possible to obtain the identifying code picture with transparent background, in picture, include true checking
Code and interference identifying code, below, next introduce needs identifying code picture is entered taking identifying code picture as shown in Figure 2 as a example
One step is processed.
Step 103, acquisition identifying code background picture, carry out identical to described true identifying code and identifying code background picture
