ABSTRACT
Generally, Compression-Then-Encryption (CTE)
paradigm meets the requirements in many secure
scompression and encryption needs to be reversed in
some other situations. Practically, image encryption has
to be conducted prior to image compression. For
designing a pair of image encryption and compression
algorithms such that compressing the encrypted images
can still be efficiently performed, there is some problem.
Most of the existing Encryption-Then-Compression
(ETC) solutions induce significant penalty on the
compression efficiency. High level of security is being
provided in the proposed image encryption scheme
operated in the prediction error domain. It is also
observed that in terms of compression efficiency, the
proposed compression approach applied to encrypted
images is only slightly worse than the state-of-the-art
lossless/lossy image coders, which take original,
unencrypted images as inputs. In this paper, we design a
highly efficient image ETC system, where both lossless
and lossy compressions are considered. We also
demonstrate that an arithmetic coding-based approach
can be exploited to efficiently compress the encrypted
images.
