Data hiding in encrypted images based on predefined watermark embedding before encryption process
作者：
Highlights：
• We provide an approach of hiding a message into an encrypted image.
• We show that the embedded message can be read whether the image is encrypted or not.
• We present an implementation of our method based on LSB substitution scheme and RC4.
• We discuss the performances and the security of the proposed implementation.
• We precise how our approach can be used for verifying image reliability.
