Abstract
The invention discloses a kind of method for generating sliding identifying code picture, this method realizes two width pictures of pair of sliding picture validation code by forming contour mould and isolating sliding picture two parts from background picture according to contour mould；The two width pictures: a width is the sliding picture cut according to profile, and a width is the background picture for obscuring outline portion.Compared to the prior art a kind of method of generation sliding identifying code picture of the invention, can produce the identifying code sliding picture of complex outline, to increase the difficulty cracked；Realization of the invention is fairly simple, taking cost into account both economical；The shape that sliding picture can regularly be replaced, to enhance the difficulty that picture cracks；To ensure that the safety of WEB system.
Description
Technical field
The present invention relates to picture validation code field, specifically a kind of method for generating sliding identifying code picture.
Background technique
Crawler or other auto logging softwares log on to system to current WEB system in order to prevent, are generally used verifying
The mode of code is used to distinguish artificial login or software logs in；There are many kinds of identifying code modes, the sliding of existing interactive mode
Identifying code is largely that the mouse motion track of user is first recorded with js by method, then continuous to collect different positions
Track is set, encounters identical position later, is just replayed with track array.Wherein picture sliding type is more friendly to user
It is good, while can also increase the difficulty cracked to a certain extent；With the development of artificial intelligence technology, picture breaking techniques are also more next
Stronger, this just requires the picture validation code of generation higher and higher.
Summary of the invention
Technical assignment of the invention is to provide a kind of method for generating sliding identifying code picture.
Technical assignment of the invention is realized in the following manner:
A method of sliding identifying code picture being generated, this method is by forming contour mould and according to contour mould from Background
Piece isolates sliding picture two parts, realizes two width pictures of pair of sliding picture validation code；The two width pictures: a width is
The sliding picture cut according to profile, a width are the background pictures for obscuring outline portion.
The contour mould is that there are two types of the profile diagram that the color of significant difference is formed, the corresponding profiles for a secondary tool
Figure prepares a secondary background picture.
The contour mould passes through manual drawing or Program Generating.
The profile diagram and background picture are loaded into the memory picture that system forms RGB mode.
From a random position for the background picture as base coordinate, then by being compared with profile diagram,
Form the picture that a width is separated according to profile diagram part from background picture.
The pixel of the profile diagram is divided into two types: one is background parts, another kind is outline portion.
The rgb value of the two kinds of pixel is obviously distinguished.
Each pixel of the scanning profile diagram, extracts the pixel coordinate value of profile diagram, then with this coordinate value from
Sliding picture is extracted in background picture.
The picture that the slave background picture is separated carries out Fuzzy Processing.
Compared to the prior art a kind of method of generation sliding identifying code picture of the invention, can produce complex outline
Identifying code slides picture, to increase the difficulty cracked；Realization of the invention is fairly simple, taking cost into account compare through
Ji；The shape that sliding picture can regularly be replaced, to enhance the difficulty that picture cracks；To ensure that WEB system
Safety.
Specific embodiment
Embodiment 1:
A method of sliding identifying code picture being generated, this method is by forming contour mould and according to contour mould from Background
Piece isolates sliding picture two parts, realizes two width pictures of pair of sliding picture validation code；The two width pictures: a width is
The sliding picture cut according to profile, a width are the background pictures for obscuring outline portion.
The contour mould is the tool of a secondary manual drawing there are two types of the profile diagram that the color of significant difference is formed, it is corresponding described in
Profile diagram prepare a secondary background picture；The profile diagram and background picture are loaded into the memory that system forms RGB mode
Picture；From a random position for the background picture as base coordinate, then by being compared with profile diagram, formed
The picture that one width is separated according to profile diagram part from background picture；The pixel of the profile diagram is divided into two types: one
Kind is background parts, and another kind is outline portion；The rgb value of the two kinds of pixel is obviously distinguished；Described in scanning
Each pixel of profile diagram, extracts the pixel coordinate value of profile diagram, and cunning is then extracted from background picture with this coordinate value
Motion picture cartoon；The picture that the slave background picture is separated carries out Fuzzy Processing.
Embodiment 2:
A method of sliding identifying code picture being generated, this method is by forming contour mould and according to contour mould from Background
Piece isolates sliding picture two parts, realizes two width pictures of pair of sliding picture validation code；The contour mould is program
It generates, what is ultimately generated is that the profile diagram that is formed there are two types of the color of significant difference of a secondary tool (drawn with black by such as white background
One circle of stroke, definition black circle are profile)；Have this profile diagram, then prepare a secondary background picture can be carried out as
Lower processing: profile diagram and background picture are loaded into the memory picture that system forms RGB mode；From random one of background picture
Position is as base coordinate, then by being compared with profile diagram, to form a width according to outline portion from background separation
Picture out；For example profile diagram is the picture of 100*100 pixel, background picture will select length and width pixel to be all larger than equal to 100
Picture, the pixel of profile diagram is divided into two types: one is background parts, another kind is outline portion；Two kinds of picture
The rgb value of element can be distinguished obviously；By each pixel of scanning profile figure, to extract the pixel coordinate value of profile, so
Sliding picture is extracted from background picture with this coordinate value afterwards；The part of background separation carries out Fuzzy Processing；Thus obtain
Two width pictures of pair of sliding picture validation code: a width is the sliding picture cut according to profile, a width is to obscure profile
Partial background picture.
The technical personnel in the technical field can readily realize the present invention with the above specific embodiments,.But it answers
Work as understanding, the present invention is not limited to above-mentioned several specific embodiments.On the basis of the disclosed embodiments, the technology
The technical staff in field can arbitrarily combine different technical features, to realize different technical solutions.
