Degrade image quality while embedding external data in a JPEG compressed image under a single framework. · Achieve scrambling–embedding using the properties ...

This paper gives a comprehensive cryptanalysis of the image scrambling scheme, and draw a conclusion that it is not sufficiently secure against various.

This paper proposes a novel method of unified data hiding and JPEG scrambling. This differs from the traditional image encryption algorithms in that, ...

By rearranging the DC components, we expect to achieve scrambling effect without sig- nificantly affecting the bitstream size. However, the outline of the ...

Wyner has proposed an elegant one-dimensional (1-D) scrambling scheme without bandwidth expansion, making use of the discrete prolate spheroidal sequences (DPSS) ...
