Beyond format-compliant encryption for JPEG image

作者：

Highlights：

• Significantly increase the scope of permutation for DCT coefficients.

• Robust against sketch attacks.

• Offer extra feature of data embedding to format-compliant encryption.

• Design VQD (virtual queue decomposition) data representation scheme where carrier capacity can be increased without giving any impact to bitstream size.

• Design an adaptive scanning order to suppress the bitstream size increment.
