Description
Technical field
The present invention relates to identifying code correlative technology field, particularly a kind of method for generating picture verification codes and system.
Background technology
Because be simple and easy to the reasons such as use, in present internet, the identifying code of main flow is picture validation code.Picture validation code and image processing techniques closely bound up, as: the embedding of character, the interpolation etc. of noise, need to use basic image procossing knowledge.And picture validation code crack the complexity just seeming and compare, it not only needs the picture processing knowledge of specialty, also needs the knowledge of artificial intelligence aspect, but, along with the development of artificial intelligence and the popular of Open-Source Tools, simple picture validation code identification becomes also more and more easier.
At present, the design of picture validation code roughly can be divided into following three kinds with image content:
(1) it is a kind of using random character, numeral as the identifying code of image content for using the most basic, the most popular.This identifying code character length is all fixing (length is 4) usually, can add corresponding interference element as required, such as: background colour, interfering line etc. when random character.In this verification code system, two kinds can be divided into again according to interference element feature: 1, adopt relatively-stationary disturbing factor.This identifying code interference element naked eyes seem that change is very large, but change not quite concerning computing machine, such as background colour, even if background colour constantly changes, but are generally all easy to remove; The position saying character for another example even font is all fixing or character string overall left and right drift, and in fact be all easy to find character region for computing machine, this identifying code cracks than being easier to.2, disturbing factor has certain randomness.This identifying code disturbing factor has had larger randomness, the relative position, the character anglec of rotation etc. of the position of such as interfering line, the font of character, character are all in continuous change, but this identifying code Consumer's Experience is not generally very good, such as character rotates, character choosing dress direction and angle are all unfixed under normal circumstances, need the subconscious labour contractor of people to tilt and just can see clearly when naked eyes identification; The change of character font is all adopt different font modes in different picture usually, and the font in same pictures is all the same mostly, even employing multiple font, such as: hollow font, solid font, up and down dichromatism process, Shadows Processing etc., these are nothing but that several identifying code has been merged into one piece in fact, the difference of front and back two pictures is too large, affects Consumer's Experience.
(2) using professional knowledge as the identifying code of image content.Such as: the stronger website of mathematics major can adopt integration conventional in mathematics to be used as identifying code content, and identifying code needs the result of integration; The website that Electronics Specialties is stronger can adopt similar " unit of electric current is ohm ", and you only need correct judgment just.
(3) using the image of complexity as identifying code content.Such as one the complete figuratum picture of band, middlely does certain rotation to a border circular areas, and needing the region in the middle of rotating to make pattern be recovered to a complete image during checking, to calculate checking correct; Or a kind of pattern with several doggies, you need to answer in pattern have doggie etc.
The shortcoming of prior art
The interference effect that the existing disturbing factor seeming comparatively complexity plays computing machine is in fact very little, and some seems, and simple disturbing factor computing machine is very difficult to be identified.For traditional picture validation code system, the effect that background colour plays is almost negligible, in order to naked eyes can identify preferably, the color of character significantly will distinguish with background colour certainly, if can not well distinguish, the difficulty of people's naked eyes identification will affect Consumer's Experience very greatly, if but background colour is easily distinguished, so those background colours seeming complexity are very easy to for computing machine, such background colour does not just have due effect, and the background colour of complexity is to some anomalous trichromatisms, colour blindness user has serious interference effect, be unfavorable for their use, the distortion of some identifying codes employing character is as disturbing factor, and existing distortion is all that the mode adopting character to rotate is carried out, because the direction of each character choosing dress is different, and will be comparatively difficult when such naked eyes identification,
For the identifying code of some complexity, such as each character has distortion, and the distortion dynamics of each character, direction are not identical, this identifying code machine is difficult to identify really, but the identification of people's naked eyes is very difficult, is unfavorable for Consumer's Experience, these are obviously unfavorable for the experience of user, network system serves people after all, and the first effect of system should be to provide service, instead of go to prevent others go illegal use it.
Summary of the invention

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Be illustrated in figure 1 the workflow diagram of a kind of method for generating picture verification codes of the present invention, comprise:
Step S101, comprising: from character set, select the character string that a group comprises multiple character at random, the length of described character string is determined at random;
Step S102, comprising: play up process to a kind of word style and word size of the Stochastic choice from font set of each character included by described character string and obtain rendering characters, described fontlib comprises multiple font, and often kind of font has multiple font size;
Step S103, comprising: carry out distortion process to each described rendering characters and obtain warped characters;
Step S104, comprising: generate the picture comprising multiple described warped characters;
Step S105, comprising: on described picture, generate at least one interfering line obtain picture validation code, and the trajectory random of described interfering line generates.
Wherein, in step S101, character set be preferably through screening by numeral, the character string that forms of letter, centre eliminates the character easily obscured in picture, such as I and 1,6 and b etc.
In step S102, font set comprises n kind font, such as, and often kind of font has m kind font size, can be: the regular script of little three font sizes, the Song typeface of little three font sizes, the circle of little three font sizes, the regular script of No. three font sizes, the Song typeface of No. three font sizes, the circle of No. three font sizes, the regular script of little four font sizes, the Song typeface of little four font sizes, the circle etc. of little four font sizes.For each character string, such as: 4B69, it character comprised is: 4, B, 6, 9, a word style and word size is selected respectively to each character, such as: the regular script of little three sizes of 4 selection, B selects the circle of No. three font sizes, the circle of little four font sizes of 6 selection, the Song typeface of 9 selections No. three font sizes, then the font size of each character and font different, for the character of different font size different fonts, the naked eyes of people can be easy to identify, and machine identifies because needs extract feature, when the font selected by font size difference is different, feature extraction is carried out for the font that different font size is different required for it, and the word style and word size selected by different characters is at random, the difficulty of machine recognition increases greatly.
To the distortion of character in step S103, distortion then just to character shape, instead of character is rotated, due to the distortion just carried out character shape, the naked eyes of people still can identify, but for machine, because it does not know which type of distortion character shape has done, its feature has no way of selecting, and difficulty improves greatly.
The interfering line increased in step S104, can distinguish itself and identifying code well for naked eyes, but concerning machine, and the interfering line increased can cause cannot extracting suitable characteristics during its identification to character, thus causes identifying that difficulty increases.
Interference element of the present invention only makes the interfering line of with the naked eye easily identification and carries out distortion to character instead of carry out the rotation of character, and these factors improve the Consumer's Experience of identifying code significantly; Unfixing, the interfering line track of character length unfixing, character font is different, increase the difficulty of computer recognizing identifying code, effectively ensure that the security of system.
Wherein in an embodiment:
Also comprise identifying code parameters acquiring procedure, described identifying code parameters acquiring procedure comprises: provide request in response to identifying code, the application identities included by request is provided according to described identifying code, obtain the identifying code parameter corresponding to described application identities, described identifying code parameter comprises minimum permission length and maximum permission length, picture color and the photo resolution of character string;
And described character string is selected in step, the length of described character string is determined at random between described minimum permission length and maximum permission length;
And in described picture pre-generatmg step, the picture color of described picture included by described identifying code parameter and photo resolution are determined.
Present embodiment enhances the versatility of verification code system, because a set of identifying code can be applied to multiple system in practice, but, in order to better Consumer's Experience machine security needs, the characteristic parameter difference that different systems is sometimes required, picture size such as required for mobile terminal can be different according to the difference of resolution, the color of picture can change according to the change of theme color, so need a maneuverable configuration-system to carry out personalized optimum configurations for different application, thus verification code system can be applied and multiple application, and the configuration of parameter can line change at random at any time completely, enhance the dirigibility of system wind control.
In the present embodiment, for different application, different identifying code parameters can be pre-set, thus the length of control string, picture color and photo resolution etc.
Wherein in an embodiment, described distortion process comprises: on each described rendering characters, select at least one position as treating distortion position, treat described in each distortion position carry out upwards translation, translation downwards, to left or to right translation.
In the present embodiment, to the distortion of character string be not to the rotation of character but to character different parts up and down, the translation of gauche form, preferably, this translation is smooth translation.Owing to just doing translation to the different parts of character, for naked eyes, still can identify well, but concerning machine, because machine is all generally carry out feature identification, namely distinguish obvious color on picture with background color, extract multiple different point thereon as unique point, then according to the position at unique point place, from database, the word that unique point is identical or similar is selected.But after adopting the distortion mode of the present embodiment, the position of the unique point of identifying code makes a change, and the unique point changed is Stochastic choice, therefore, machine is difficult to identify it.
Wherein in an embodiment, described in every bar, interfering line generates in the following way:
The multiple tracing point of Stochastic choice on described picture, generates the polynomial equation track comprising all described tracing points.
Preferably, interfering line adopts four random points in picture to determine a cubic equation track.Add interfering line, specifically which type of font is not known due to machine, can only extract minutiae when it identifies, therefore interfering line is increased, be equivalent to unique point when adding machine recognition, but the unique point increased not is the fact characteristic point of identifying code, therefore machine is difficult to identify it.
Determined the mode of a polynomial equation track by multiple point, can adopt existing techniques in realizing, such as, tool-class inside java storehouse realizes.
Wherein in an embodiment, described interfering line is identical with the color of described character, and gradual change between the breadth extreme of all described warped characters of the thickness of described interfering line and minimum widith.
In the present embodiment, the color of interfering line is identical with character color, then machine is difficult to identify more, and the thickness of interfering line is gradual change, also more improves the identification difficulty of machine.

Step S203, random string generates.The character string of corresponding length is selected at random as random string, length Stochastic choice between character maximum length and minimum length of random string in character set.This character set be through screening by numeral, the character string that forms of letter, centre eliminates the character easily obscured in picture, such as I and 1,6 and b etc.
Step S204, random string is played up.
From CMS, read the background picture that the length of picture and width generate corresponding size, and on background picture, play up above-mentioned random string.A kind of font of selecting from font set that each character of random string is random in the process played up carries out initialization, the set of n × m size that font is made up of n kind font, m kind font size in font set; Distortion process can be done to each character after the playing up of font, distortion be not here to the rotation of character but to character different parts up and down, the smooth translation of gauche form; Certain spacing can be according to circumstances retained in the middle of character, when spacing is for illustrating two Characters Stucks time negative in the process played up; So traditional character can be avoided to rotate the not good problem of the Consumer's Experience brought, and can ensure that the identification of character naked eyes has higher discrimination.
Step S205, interfering line generates.Interfering line can add in the picture of step S204 generation as interference element; wherein; each interfering line is all the cubic equation track determined by the random point of four in picture; the length of interfering line and the width of picture, length are relevant; and owing to being determined by four random points, therefore its track can random variation.Interfering line and character homochromy, and all gradual changes in certain scope of interfering line thickness, and ensure that the width of lines is between the breadth extreme and minimum widith of character, can prevent identifying code from cracking the removal of interfering line in process like this, thus ensure the difficulty that identifying code cracks.
