Abstract: This paper may deals with the miscellaneous troubles that may be occurs during the irrevocable compression applied on an encrypted grayscale image. This work is a comparative learn with diverse methods of irrevocable compression such as Compressive sensing technique and Iterative reconstruction technique on encrypted grayscale image. But they practiced a multiplicity of limitations. The major obscurity is to achieve higher compression ratio as well as the better quality of the reconstructed image. The higher compression ratio and the smoother the original image may furnish the better quality of the reconstructed image.

Keywords: Image compression, image encryption, image decryption, image decompression, image reconstruction.
