[0204] Alternatively, in the first step, the number of bits of depth of the screenshot data is obtained, which is recorded as M=8;

[0205] The second step is to convert the pixel value (155, 111, 18) of each pixel in the screenshot data (taking the pixel (554, 1243) as an example) into binary (10011011, 1101111, 10010) and the screenshot code (96B53D57F00E578698AF448F841028FDCBE20D7CDD8007F5ECD6EFF9) into binary (1001011010110101001111010101011111110 00000001110010101111000011010011000101010111101000100011111000010000010000001010001111110111001011111000100000110101111100110110000000000011111110101111011001);

[0206] The third step is to convert the binary pixel value (10011011, 1101111, 10010) of each pixel in the screenshot data (taking the pixel (554, 1243) as an example) into a pixel value with 8 bits (10011011, 01101111, 00010010);

[0207] Step 4: Get the first digit of the screenshot code, recorded as N=1; convert the digit 1 to 8, that is, 11111111;

[0208] The fifth step is to calculate the converted pixel value (10011011, 01101111, 00010010) and the converted 8-bit value 11111111 to obtain the screenshot security data (taking the pixel point (78, 1919) as an example, the pixel value of this point is (01100100, 10010000, 11101101)); the binary pixel value can also be written as decimal (100, 144, 237) or hexadecimal (64, 90, ED).
