Using mozaiq practitioners and learners can hide secret, encrypted messages inside an image that will be invisible to the naked eye and undetectable to everything but careful mathematical analysis.

Even if detected, the message will be...

  • stored encrypted using a password of your choice;
  • all but impossible to read!

Hiding a message like this is known as steganography; part art form, part science and many different methods to do it. The Wikipedia article on steganography provides information on this practice.

Visitors to mozaiq can use either an image that they provide or a random image from the mozaiq library.

To use a personal image - select 'browse' in the box at the top right.

To use a random mozaiq image - Leave the same field blank.

Download the image (with hidden message) and pass the message along to fellow spies colleagues/learners/etc., along with the website address; that way, they can recover the message using the decryption page.

Visit http://mozaiq.org/encrypt/ to hide your message in an image.

Family Learning Providers will have great fun with the young learners. Oh, don't forget to tell them the password.
