Batch png lsbhiding. Can be used to generate data set

lsbhide.py

Install stegano pip3 install stegano

Change the target_dir. It refers to the directory containing cover images. hide_len is the range of random ascii string's length. secret.save("")is the path of result. The directory should be made before running if it is not existed.

Run python3 lsbhide.py

It implements batch png lsbhiding via stegano, the hide_msg are ascii strings which are randomly generated.

bitStream

pip3 install --upgrade pip #pip3 >= 19.3
pip3 install opencv-python

The embedding rate is around(lower than) 80%. It can be changed by s. Change cv.imwrite('',imgStego) to path of your results. The directory should be made before running if it is not existed. Change target_dir to the directory containing cover images.

Run python3 lsbhide_bin.py

It implements batch png lsbhiding by generating a random bit stream of certain length. The length of the bit stream depends on the embedding rate you want. It also normalizes the bit stream and gets the positions to embed randomly.
