Inspiration
We have always been interested in steganography. This hackathon provided us with an excuse to actually delve into it.
How it works
Steganography is a process of using the colors of pixels in an image to store other useful data. This is a small tool to store text inside an image using steganography. The resulting image can then be used to send messages literally hidden in plain sight. The tool can also extract text for someone who knows of its presence within an image.
Challenges I ran into
We originally envisioned the project focusing on Twitter and using Twitter as a medium for exchanging images with messages secretly inside. However, we soon learned the lossy compression algorithm twitter runs foils our method of storing data.
Accomplishments that I'm proud of
It works. It actually works
What's next for Hide data for me
We could try using other steganography algorithms to preserve the data even through lossy compression algorithms. This will allow us to use social media to mass distribute steganographic images.
