A reversible extended secret image sharing scheme based on Chinese remainder theorem

作者：

Highlights：

• CRT over polynomial ring is used to share secret image.

• The scheme uses LSB substitution to generate meaningful stego images.

• Both secret image and cover image can be recovered losslessly.
