According in the security documents that the composite anti-fake document structure tree method of the embodiment of the present invention generates, according to false proof demand, one or more the false proof figures in false proof shading figure, anti-duplicating figure, micro text figure and two-dimension code pattern can be added in documentation page.Can make to demonstrate the figure different from original paper in the documentation page copied according to the anti-duplicating figure added, consumer can the true and false of identification document intuitively.When adding micro text figure in security documents, key message micro in document can be generated micro text figure, realize key message to a certain degree hide, two-dimension code pattern can also be added in addition in security documents, realize the inquiry being carried out anti-counterfeiting information by Quick Response Code, be convenient to the Antiforge inquiry of consumer to document.Therefore the security documents of security documents generation method generation according to the above embodiment of the present invention, reduces the difficulty that consumer identifies true and false document, improves the antifalse effect of security documents.
In the embodiment of the present invention, in the documentation page of specifying, the false proof figure of true-to-shape is added by preset rules, generate security documents page, the false proof figure wherein added can be one or more in false proof shading figure, anti-duplicating figure, micro text figure and two-dimension code pattern.
When adding false proof shading figure in the documentation page of specifying, comprising: in the documentation page of specifying, determine multiple reference mark; Generate the SPL by multiple described reference mark; False proof shading figure is formed by multiple described SPL; Described false proof shading figure is joined the assigned address in the documentation page of specifying, generate security documents page.
In the embodiment of the present invention, structure batten is exactly by given one group of reference mark (one group of XY value) in the O-XY coordinate system of specifying, such as given following four reference mark (X is value between 1 to 100);
A(10，15)、B(28，78)、C(68，32)、D(76，12)
According to four reference mark provided, calculate a function Y=F (X);
Then X is substituted into this function entirely from 1 to 100, just obtain 100 points, by 100 the some structure SPL drawn.
When the number ratio at reference mark is more, by reference mark segmentation computing function, such as front 4 dot generation Y=F1 (X), lower four another functions of dot generation Y=F2 (X) ... SPL is combined into by multiple sectional curve.
Keep level and smooth for making the junction of the curve of segmentation, certain condition of continuity (continuitycondition) need be determined, by the parametric derivative connected at the public semi-match of segment of curve, thus set up parametric continuity (parametriccontinuity).
Particularly, generate the SPL by multiple described reference mark in the embodiment of the present invention, comprising: determine the SPL by multiple reference mark by cubic spline interpolation.
The piecewise function that cubic spline generates is cubic polynomial, cubic spline differential technique is provide a rational half-way house between the dirigibility of SPL and computing velocity, compared with higher level polynomial expression, cubic spline function only needs less calculating and storage space, and it is more stable, compared with polynomial of lower degree, cubic spline seems more flexible when simulating Arbitrary groove profile.
Mathematically, the quantitative description of smooth degree is: the k order derivative of function (curve) exists and continuously, then claims this curve to have k rank slickness.Wherein the smooth degree of the higher curve of exponent number is better.
Can the curve obtained be made to have higher-order slickness in the situation compared with polynomial of lower degree by cubic spline difference.
Particularly, determine that the method for cubic spline function is in the documentation page of specifying, set up O-XY coordinate system, in the O-XY coordinate system set up, note cubic spline function is designated as s (x), and its interval of definition is [a, b];
This cubic spline function s (x) meets at each minizone [Xi-1, Xi] on be a cubic polynomial function, and on whole interval [a, b], its second derivative exists and continuously, so can ensure that cubic spline function is continuous in the second derivative of each Nodes.
Cubic spline functions defining method is: given function f (x) at n+1 node x0, x1 ..., the functional value at xn place is y0, y1, ..., yn, asks cubic spline function s (x), make its meet
s(xi)＝yi,i＝0，1，…，n；
Piecewise linear interpolation, in two parameters of the linear function of each section, is uniquely determined by two equations (functional value of two end points is set-point); For cubic spline interpolation, the cubic function on each interval has four parameters, and is that set-point is merely able to generation two equations by the functional value of two end points on this interval, and only this is not enough to uniquely determine four parameters.Notice the requirement of cubic spline function to whole smooth, its second derivative exists and continuously, considers that the relation of number of parameters and equation number is as follows from the angle of the overall situation:
Parameter: each segment is determined 4 parameters, n segment determines 4n parameter altogether;
Equation: each segment obtains 2 by given function value, equation, n segment amounts to 2n equation;
Slickness requires that the single order at each internal node place, second derivative are continuous, and show that its Derivative on the left or on the right is equal, therefore, each node produces 2 equations, amounts to 2 (n-1) individual, can obtain 4n-2 equation thus, now also need to determine two equations.
For this reason, conventional method is to boundary node subsidiary boundary condition except functional value, by respectively determining that a boundary condition obtains two required equations for two, left and right end points, wherein determines that the mode of end points boundary condition has three kinds:
(1) m boundary condition: s'(X0)=m0, s'(Xn)=mn, namely the first derivative values of two boundary nodes is set-point: m0, mn.
(2) M boundary condition: s " (x0)=m0, s " (xn)=mn, namely the second derivative values of two boundary nodes is set-point: m0, mn.
Especially, when m0 and mn is zero, natural boundary conditions is called.
(3) periodic boundary condition: s'(x0)=s'(xn); S " (x0)=s " (xn).
