A data hiding scheme using parity-bit pixel value differencing and improved rightmost digit replacement

作者：

Highlights：

• A novel embedding method based on pixel difference and digit replacement techniques.

• This improves the embedding capacity of classical pixel difference method.

• The closest selection process is used to maintain the visual imperceptibility.

• This method reduces the risk of RS and PDH steganalysis detection attacks.
