Abstract EN
This paper proposes a new steganography method for hiding data into dynamic GIF (Graphics Interchange Format) images.
When using the STC framework, we propose a new algorithm of cost assignment according to the characteristics of dynamic GIF images, including the image palette and the correlation of interframes.
We also propose a payload allocation algorithm for different frames.
First, we reorder the palette of GIF images to reduce the modifications on pixel values when modifying the index values.
As the different modifications on index values would result in different impacts on pixel values, we assign the elements with less impact on pixel values with small embedding costs.
Meanwhile, small embedding costs are also assigned for the elements in the regions that the interframe changes are large enough.
Finally, we calculate an appropriate payload for each frame using the embedding probability obtained from the proposed distortion function.
Experimental results show that the proposed method has a better security performance than state-of-the-art works.
