NOGRAPHY
Team Project @HTWG WS2020/21

What is NOGRAPHY?

NOGRAPHY is an encoding engine, that uses a dummy text and assigns different fonts to different letters in order to embed information. These fonts are hardly recognizable by sight but easily differentiable for the neural network of the engine, which also contains an error correction mechanism for better stability.

You can use the app here: NOGRAPHY App

Boundaries:

• please use short texts and even shorter secrets
• The website is like an old diesel engine: it is slow in the beginning, but then it speeds up.
