I have written my own software to do Steganography. Basically, I am dividing the message (text) into bits and then hide them into pixels in jpg. After that I am saving the bitmap into .png (because .jpg's conversion may destroy the hidden message).
I would like to test my software. Do you know any framework that may find my text hidden in the image file? Or even if such a framework will be able to detect the fact of hidden message?
I am wondering what is the ideal implementation of steganography for images? I would like to master it. I have written my code just with my knowledge and my ideas, without looking into any theories. After speaking with my professor, he suggested that others may have implemented the same idea, and there may be some ways to make it better. Does anyone have some suggestions for me? Any name of concepts? Any algorithm names? Any papers?
