The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
Example 1
The form information is one kind of information interaction, and the interaction process is as follows: and the user perfects the form information at the web end or the mobile end and submits the form information to the background.
In the prior art, when the form information is submitted to a background, the form information is generally submitted according to a certain rule in a plaintext mode, the form information is easy to find and easy to tamper, and the safety factor is low.
In order to avoid form information being tampered, the application provides a form information submission method, and the core idea is as follows: converting the form information into binary codes, reading bit information of pixels of a preset picture, writing the binary codes of the form information into the bit information of the pixels of the preset picture according to a preset rule, converting the bit information of the rewritten pixels into pictures, uploading the pictures to a background, after receiving the pictures, reading the bit information of the pixels of the pictures according to the preset rule by the background, forming the binary codes by the read information, and converting the binary codes into characters so as to obtain the form information;
the form information submitting method is used for submitting the form information by taking the picture as a medium and through a preset rule, and the form information is hidden in the picture.
FIG. 1 is a flow chart diagram of a form information submission method of the present invention;
the invention takes an example that a user submits form information to a background on a web page of a PC web end or a mobile end h5 as an example, and as shown in figure 1, the form information submission method provided by the invention is applied to the web page of the PC web end or the mobile end h5 and comprises the following steps:
step 11: acquiring form information;
the acquired form information is the form information to be submitted by the user, and when the user completes the filling of the form information and the step of submitting the form information is carried out, the form information at the moment is acquired;
after obtaining the form information, carrying out the following steps;
step 12: converting the form information into binary codes;
the binary code is a code of '0101.. 0101', the form information mainly includes text, such as chinese characters, letters, and the like, and the conversion of the form information into the binary code means that the text content is converted into the binary code, in this embodiment, the form information is Unicode code, for example, in the coding process, the binary code corresponding to the characters is generally represented by 4 bytes, and when the characters are less than 4 bytes, 0 is supplemented forward, that is, the binary code bit number of the characters of the Unicode code is generally 32 bits, for example, the text 'single' is converted into the binary code of '00000000000000000101001101010101'.
Step 13: acquiring a preset picture, the number of pixels of the preset picture and bit information, wherein the preset picture is marked as a first picture;
specifically, one or more pictures are preset; when the number of the preset picture and the number of the pixels of the preset picture and bit information are directly obtained when the number of the preset picture is one, the picture is a preset picture appointed in the system, the pixel is appointed to be large enough according to practical application, and the phenomenon that the number of bits of binary coding of form information is larger than the number of the pixels is avoided;
when the number of the preset pictures is multiple, acquiring all the preset pictures and the corresponding pixel number and bit information, selecting the corresponding preset pictures according to the binary coded digits acquired in the step 2, for example, selecting one preset picture with the pixel number being more than or equal to the binary coded digits, and recording the picture as a first picture;
specifically, taking the JPG format as an example, 1 pixel of a picture is 24 bits; taking the PNG format as an example, 1 pixel of a picture is 32 bits; in this embodiment, a picture in the JPG format is taken as an example for explanation, that is, the preset picture in this embodiment is in the JPG format.
Step 14: rewriting binary codes into bit information of pixels of the first picture according to a first preset rule to generate a second picture;
the first preset rule is as follows: writing the binary code of the form information from the nth pixel, writing the binary code into one bit of bit information of the pixel of the first picture, and writing one bit of the binary code into one pixel; wherein n is more than or equal to 1; in the picture in the JPG format, 1 pixel is 24 bits, namely, one bit of 24 bits in bit information rewritten into the pixel during rewriting;
when the binary code is written into the bit information of the pixel of the first picture, the binary code of the form information is written into the n-th pixel one by one;
as a specific implementation of this embodiment, the first preset rule refers to: writing binary codes of the form information one by one from the 3 rd pixel, rewriting the binary codes into the last bit of the bit information of each pixel, and writing one bit in the binary codes into the last bit of the bit information of one pixel;
taking the above-mentioned word "single" as an example, the binary code of the word is 32 bits, the binary code of the chinese character is rewritten into the bit information of the pixel of the first picture according to the first preset rule, that is, the rewriting is started from the 3 rd pixel of the first picture, the first bit of the binary code of "single" is rewritten into the last bit of the 3 rd pixel of the first picture, for example, the first bit of the binary code of the word "single" is 0, the bit information of the 3 rd pixel of the first picture is "01.. 01", that is, the bit information of the 3 rd pixel of the rewritten first picture is "01.. 00";
the second bit of the binary code of the character 'single' is rewritten into the last bit of the 4 th pixel of the first picture, and by analogy, the binary codes of the Chinese characters are completely rewritten into bit information of the pixel of the first picture;
and rewriting all binary codes of the form information into bit information of pixels of the first picture through the rewriting process to form a picture, namely the second picture.
Step 15: submitting a second picture; and submitting the second picture to the background.
By the aid of the hidden form submitting method, risks of tampering form information can be reduced, and safety factors of form information submission are improved.

referring to fig. 2, the present invention further provides a form information reading method, which is applied to a background, and is used to ensure that form information rewritten in a first picture can be obtained, and ensure correctness of form information submission, and includes the following steps:
step 21: acquiring a second picture;
the second picture is submitted by the form information submitting method.
Step 22: reading bit information of pixels of a second picture according to a second preset rule to obtain binary information;
the second preset rule corresponds to the first preset rule, and the second preset rule is as follows: reading one bit rewritten according to a first preset rule in bit information of each pixel from the nth pixel of the second picture; for example, the first preset rule of this embodiment is to write the binary code of the form information from the 3 rd pixel, and rewrite the binary code into the last bit of the bit information of each pixel; therefore, the corresponding second preset rule is that the last bit of bit information of each pixel is read from the 3 rd pixel of the second picture, and the read information is combined to form binary information;
the digit of the binary code of the form information is N; and when the bit information of the pixels of the second picture is read according to a second preset rule, reading is started from the nth pixel, and the binary information obtained by reading the bit information of the N pixels is the binary code of the form information.
Step 23: and converting the binary information into characters to obtain form information.
Specifically, the characters converted from the binary information are form information.
