Scramblingembedding for JPEG compressed image
Degrade image quality while embedding external data in a JPEG compressed image under a single framework. Achieve scramblingembedding using the properties derived from the components (i.e., DC coefficient and AC coefficient) of a JPEG compressed image. Minimize the bitstream size increment caused by scramblingembedding, which is inevitable for the conventional methods. Achieve scalability in both image quality degradation and data payload. Achieve complete reversibility.
