Steganography is the practice of hiding messages within media. The picture below is a form of physical steganography, but don’t worry, you don’t have to be both an artist and an expert in exotic ciphers to be able to encode messages. Modern digital steganography tools make this process a snap.

Steganart example. Within this picture, the letter positions of a hidden message are represented by increasing numbers (1 to 20), and a letter value is given by its intersection position in the grid. For instance, the first letter of the hidden message is at the intersection of 1 and 4. So, after a few tries, the first letter of the message seems to be the 14th letter of the alphabet; the last one (number 20) is the 5th letter of the alphabet.

With online photo encrypters such as Mozaiq, you simply upload your image, type in the message, and select a password that the recipient will need to know to be able to decrypt the hidden message.
