Efficient reversible data hiding in encrypted images based on multi-stage integer wavelet transform

作者：

Highlights：

• We proposed an IWT-based data hiding scheme for encrypted images.

• We further proposed an adaptive correction method to improve the embedding rate.

• The proposed method is completely reversible.

• Better reconstructed image quality is provided.

• The proposed method achieves high embedding capacity.
