Hide a Secret Message inside a Photo with Steganography

Have a secret that you want to share with others? Why not hide it in a picture? That’s a great idea, yet far from complicated. Have you ever wanted to hide a secret message inside a photo? I know that feeling too and it is a great one. Knowing that you have the power to keep your secrets safe or to communicate efficiently is amazing! That is what you get with Steganography, a special app which was developed as a first semester project of the Software Development bachelor, at the Copenhagen School of Design and Technology.

With the help of this app, you can easily encode/hide a message in a picture or turn into the one who successfully decodes secret messages out of encoded images and transmit images. You can use the camera to take your photo or select from the photos that you’ve already taken.

Like that, you can make sure that only the intended receiver can read the message, while other could just see a boring landscape photo or something similar. This is a fun and easy way to share hidden messages without anyone knowing. Just take the matter in your hands, take those pixels, twist them in a knot, and see for yourself!

However, you must understand from the start that due to the nature of steganography, images transmitted with messaging apps that compress attachments, e.g. Facebook’s Messenger, won’t contain the hidden message. Even so, it is a well-designed app, I really like the UI design and it works great on Android.

Steganography can be taken right away and yes, it is available for free. And don’t be surprised to find out that it is quite popular and is installed on more and more Android devices every day. We all like to keep our life private, so why not using such apps?
