In an optional scheme, the method can further comprise the following steps:
when the mobile phone receives the fee deduction request information firstly, acquiring a vein picture of an operation user, and sending the vein picture to a mother terminal through a mobile communication network;
and the mother terminal is used for comparing the vein picture with a preset template vein picture to determine whether the vein picture is consistent with the preset template vein picture, if so, determining that the mobile phone is a safe terminal, processing the fee deduction request information, and if not, determining that the mobile phone is an illegal terminal, and deleting the fee deduction request information.
The above determining whether the vein image is consistent with the preset template vein image by comparing the vein image with the preset template vein image may specifically include:
a parent terminal extracts an interested Region (ROI) of the vein picture to obtain a region picture, performs primary angle identification on each branch in the region picture to obtain an angle of each branch, performs gray processing on the region picture to obtain a gray picture, extracts a gray value of each pixel in the gray picture, forms a gray matrix according to the gray value of each pixel according to the position of the pixel, extracts a first angle corresponding to the first branch and the first branch in a first branch region of the gray matrix, determines a first branch and a second branch of the first branch region, divides the first branch into a first branch group according to pixel points, divides the second branch into a second branch group according to pixel points, calculates alpha position values (namely row values and column values of the matrix) of alpha pixel points of each branch line in the first branch group in the gray matrix according to a first set direction, and calculates alpha position values of alpha pixel points of each branch line in the second branch group in the gray matrix according to a second set direction Values (i.e., row values, column values of the matrix); calculating the absolute value of the difference between the α position values of the ith branch line segment in the first branch line segment group and the α position values of the h branch line segment in the second branch line segment group (corresponding to the ith branch line segment, e.g., i =2, then h =2, for distinction, described by using different letters), which is the absolute value obtained by subtracting the row value from the row value and subtracting the column value from the column value, and then combining the row value absolute value with the column value absolute value to obtain the absolute value of the difference, obtaining α absolute values, forming the x-th column element of the position matrix by sequentially combining the α absolute values, obtaining all column elements of the position matrix by traversing the first branch line segment group and the second straight line segment group, extracting the template matrix of the preset template vein picture corresponding to the first angle, obtaining the difference matrix by calculating the difference between the position matrix and the template matrix, and obtaining the difference matrix if the number y of the element values smaller than the preset threshold in the difference matrix is smaller than or equal to the number threshold, and determining that the vein picture is consistent with the template vein picture corresponding to the template matrix, and if the y is greater than a quantity threshold value, determining that the vein picture is inconsistent with the template vein picture corresponding to the template matrix.
Whether the vein image is consistent with the template vein image or not is determined in a vein identification mode, and safety is further improved.
It should be noted that the ROI region may be extracted by using an ROI algorithm, and the present application does not limit the specific manner of ROI acquisition. The method of performing the preliminary angle recognition on each branch in the region picture to obtain the angle of each branch may also adopt the existing angle recognition method, for example, directly obtain the coordinates of the pixel point of each branch, and calculate the corresponding preliminary angle according to the coordinates, where the preliminary angle is only used for the preliminary recognition and is only used for distinguishing the template matrix.
Referring to fig. 2a, fig. 2a is a schematic diagram of a gray matrix, where each square represents a gray value of a pixel point, where gray represents a gray value of a pixel point where a vein is located, and white represents a gray value of a pixel point where a non-vein is located, as shown in fig. 2a, a first branch line of a first branch in an icon is represented by 301, and a second branch line is represented by 302, where 3011 represents that 1 branch line segment (black display) in the first branch line is actually 4 branch line segments, each pixel point in a width direction may be 1 branch line segment, and 3012 represents a branch line segment in the first branch line. Because the number of pixel points occupied by branches in the vein picture is large, the vein picture can occupy a plurality of pixel points, so that the vein picture needs to be divided into a plurality of branch line segments according to the pixel points, alpha cannot be too high or too low due to the calculation reason, because the angle of the vein branch can change, the application extracts the pixel points near the intersection point of the branches for calculation, the range of the alpha can be 100,500, and in addition, the value of the alpha is controlled to reduce the calculation amount. The first setting direction may be a direction of the first branch line, as indicated by arrow 303 in fig. 2a, and the second setting direction may be a direction of the second branch line, as indicated by arrow 304 in fig. 2 a.
The principle of the above verification is that, for vein recognition, it can recognize the identity of an operation object, such as a person, because the vein shape is unchanged, but there is a difference in angle between a model vein picture and an acquired vein picture and a difference in acquisition range, which results in inaccurate recognition, the present application removes the angle difference as much as possible by means of matrix calculation, and for vein branches, if the operation object is the same person, the angle is the same, the applicant verifies that a matrix formed by the difference between corresponding gray values in the gray level images formed by the operation object is basically fixed, taking 90 ° as an example, the difference between two branches is a constant value, as shown in fig. 2b, it is assumed that the vein branches are translated (equivalent to different acquisition ranges), but the difference between row values and column values is basically unchanged, based on this principle, the influence of the range and the angle on the vein recognition accuracy can be avoided.
As shown in fig. 2b, the schematic diagram of two branches, because of the boundary of the diagram, where α =2, in practice, a value greater than 100 needs to be taken, and as shown in fig. 2b, the α position values of two branches (taking the width direction as an example, i.e. one branch line segment as an example) after displacement may be respectively (a 13, a 23) for 2 positions of the first branch 301, respectively (a 31, a 32) for 2 positions of the second branch 304, after displacement, the 2 position values of the first branch 301 are respectively (a 24, a 34), and the 2 positions of the second branch 302 are respectively (a 42, a 43), and then the absolute values of the calculated differences are respectively: subtracting the row values and the column values of a13 and a31 respectively, then taking the absolute value to obtain 22, and obtaining another absolute value of 11 by calculation in the same way; after displacement, two absolute values are calculated as: 22. and 11, calculating the difference value, determining the difference value as 0 and 0, and determining the difference value as a vein picture of the same person.
The foregoing detailed description of the embodiments of the present application has been presented to illustrate the principles and implementations of the present application, and the above description of the embodiments is only provided to help understand the method and the core concept of the present application; meanwhile, for a person skilled in the art, according to the idea of the present application, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present application.
