Embodiment 1
[0026] Such as figure 1As shown, a settlement processing system integrating medical insurance and multiple payment methods, the system includes: a security control device and a payment device; the security control device includes: a data extraction device for extracting data of each function node in the payment device and a data control device for encrypting and decrypting the function node data; the method for encrypting the function node data by the data control device performs the following steps: Step 1: first convert the extracted function node data into image data; Step 2 : Use calculus imaging to convert the image data to be encrypted into a unit image array; Step 3: Generate a key; Step 4: Encrypt, according to the generated key, perform the first chaotic random modulation on the unit image array, and then perform For the first modulus transformation, the transformed unit image array is subjected to the second chaotic random modulation, and then the second modulus tran...
Embodiment 2
[0030] On the basis of the previous embodiment, the method of converting the image data to be encrypted into a unit image array using calculus imaging in step 2 performs the following steps: Step 2.1: Convert the image data into a unit image array through the following formula : O(x,y)=S(-xv+kγ,-yv+1γ); wherein, S is the original image, O is the unit image, x is the abscissa, y is the ordinate, γ is the spacing constant, and the value range is 5~8; v is the enlargement factor, and the numerical range is 1.3~1.5; The unit image array after described transformation is represented by the following formula: Among them, f(x, y) is the unit image array; p and q are the number of unit images, k and l are natural numbers; as the result of multiplying the two by the spacing constant value γ and the amplification factor v is larger, its The higher the computational complexity, the more accurate the result, so the values of the pitch constant and the magnification factor can be adjust...
Embodiment 3
[0032] On the basis of the previous embodiment, the function node data is the data transferred between each unit and / or module and / or each device in the payment device; Data passed between modules and / or devices.
