[author here] Visualenv is a use case of a backend steganograpy engine. The main job is done in the backend.
A: The usage may not be clear from the samples. Let me explain step-wise:
1. Client sends text data to the backend to hide it in an image
2. Server;
2.1 Randomly creates a host image
2.2 Hides data in the image making use of the client's steganogprahy key in that is available in its database
2.3 Returns the stego image filename to the user (a unique name)
3. Client downloads stego image to its local.
4. Client extracts hidden data in an image by either:
4.1. Uploading image
4.2. Sending filename (assuming user let it be saved in the server)
P.S. Another user in the server cannot extract the hidden data since he cant access owner's stego key.
B: Steganographic operations are performed in the backend. Client host just waits for the result.
