About Olmaredo Stego

Steganography is a technique with the ambition to conceal secret information into other information apparently innocuous. Regarding this app, it uses spread spectrum steganography applied to images.

The basic workflow is the following:
1. Open the app and pore over the INFO tab
2. Tap on ENCODE
3. Choose an image
4. Type the message or open a text file containing it
5. Launch the process
6. Copy the decoding key in the clipboard

Now, in order to your homie to read the glorious pun you just encoded, you have to send him the processed image alongside the decoding key.
Keep in mind that the image MUST NOT be compressed in any way, otherwise the information will be lost! With default setting the image shouldn't be compressed by popular messaging application like Whastapp. But this isn't true anymore stepping up the resolution in the SETTING tab.

This is what your bro has to do:
1. Tap the DECODE tab
2. Go to the INFO tab, read it, and then tap back again on DECODE
3. Choose the received image containing the message
4. Paste the key, without white spaces or other things
5. Start the decode process
6. The message will pop up below and will be possible to copy it

If you aren't color blind, you might enjoy encoding messages into color images, just enable the color mode in SETTING. Moreover will be possible to include three times the information than in black and white, but the computation time will be longer as well.


This app origins from the assignment for the Multimedia Apps and Future Internet course of the University of Genoa, Electronic Engineering and Information Technology.
The work is completely open source, you can find the source code following the link that is here somewhere or just look for OlimexSmart on GitHub.
Special thanks to Claudio MArtino and Edoardo Lorenzetti.
