Description: A frequency-domain encryption algorithm, the image obtained through the DCT transform DCT coefficients, and then encrypt the DCT coefficients. And then encrypted DCT coefficients DCT inverse transform image data. The last of its encrypted image data linear transformation to adjust the image data ranges in [0,255]. Finally the image is encrypted
