An efficient reversible image authentication method using improved PVO and LSB substitution techniques

作者：

Highlights：

•

• Block features are embedded to improve the performance of tampered detection.

• One bit is embedded into each un-embeddable block for the authentication purpose.

• The proposed method can recover the original image if the marked image is un-tampered.
