specific Embodiment
[0072] The method for encrypting and decrypting the background picture of the slide track of the present invention will be introduced below through a specific embodiment.
[0073] Figure 9 In this specific embodiment, the background picture of the original plaintext sliding track generated on the server side. The server divides the original sliding track background image into 5 rows and 5 columns, and generates an array from 0 to (5*5-1), the array is ["0", "1", "2", "3", "4 ","5","6","7","8","9","10","11","12","13","14","15","16", "17","18","19","20","21","22","23","24"], assuming that the array after scrambling is ["20","8"," 7","4","22","5","16","23","10","15","13","3","11","24","17" ,"1","21","14","19","0","2","12","9","18","6"] to obtain the encryption factor. Then put the original sliding track background picture in accordance with this scrambled array, place the 0th at the 20th, the 1st at the 8th, the 2nd at the 7th,..., and get the sliding track background pictur...
