内容简介：
Steganography is the science of secret message delivery using cover media.

In this talk, I will introduce some novel steganographic methods based on different magic matrices Among them, one method that uses a turtle shell most interesting one. magic matrix to guide cover pixels’ modification in order to imply secret data is the newest and the Experimental results demonstrated that this method, in comparison with previous related works, outperforms in both visual quality of the stego image and embedding capacity. In addition, I will introduce some future research issues that derived from the steganographic method based on the magic matrix.
