Encrypted image-based reversible data hiding with public key cryptography from difference expansion

作者：

Highlights：

• We propose a new encrypted image-based reversible data hiding with public key cryptography from difference expansion.

• The core of the proposed scheme is to pre-process an image with the property of difference expansion before encrypting.

• The proposed scheme provide good payload and image quality.
