Imagine you have some images and want to send to your friend or something like this. you can post them simply in a social media or send with email. bot you don't want anybody can see those.
What does it mean? simply, you want to send them or even post in a social media bot no one can't see them unless your friend.
How you can do this?
so first you should have two Images, one for post in social media and it is a normal image and second one
is your main images. now you can Hide your main image in the first one and nobody can not extract that without
your permissions(with parameters).
you have this one and want to send to your friend but not in the common ways. so you pick another image and then hide this one in that one and send that to your friend or even post in internet.
the main image will hide in this image.
interesting :)
this is so much similar to the base image but the big difference is that this one includes another image. we can not understand it, even if we can find out this image includes data still can not extract data.
here our hided image in the base image.
stegano.pyfile is the main logic.encode.pyfile encode an image in another.decode.pyfile decode an image from another image.
encode.py file has two outputs, first the encoded image and second is a file.txt file that include
details and parameters that require for decoding the image.
text file with needed information is like this:
- file name: stegano_encode_1425199
- memorize: 1
- height: 1080
- width: 700
- key: 18144000
after encoding an image simply send encoded image and text file togather.
then for decoding should use the information in text file to decode the encoded image.
