Have you ever wanted to send sensitive information to someone else over the internet?
I’m sure you must’ve felt a little paranoid about your details getting stolen along the way.
Ever wished there was a way to send messages across to a friend without others knowing?
Or even not having the slightest hint that you’re sending a secret message?
Magicians often use this method to distract their audiences away from what is really happening – it’s calledmisdirection.
The method is calledsteganography.
Tina alsodiscussed steganographyback in June for Windows computers and her article is also definately worth reading.
The utility featured here today is iSteg.
As the name goes, it uses steganography to conceal messages within photos.
Think of it as “invisible ink”, if you will.
Using iSteg is pretty easy.
The output photo is aptly named ‘output.jpg’.
Renaming it won’t ruin the encryption so go ahead and rename it whatever you like.
The only change here is to uncheck the ‘Encode’ box.
Then hit ‘Process’ and the message will be revealed.
Now you are able to send anything and no one will even have a clue.
Just bear in mind that this method is more about the fun of sending secret messages.
iSteg only works on Mac OS X and is available fromhanynet.com.
The source code is also available from the website.
Can anyone tell me what was hidden in the photo above?
