What is it?
Basically, it’s the embedding of data in other data. I was just watching an episode of Numb3rs in Season 2, and they mention embedding of data in images. So I’ve been thinking of posting a photo of myself again, so I thought I’d hide it

I searched freshmeat.net and found a program that actually looked like it was maintained, Steghide. Actually, it’s already in the Debian repository, and also in the Ubuntu universe repositories

So heres the photo:

And the command to extract it is:

steghide extract -sf picture.jpg

Whats the passphrase? Well it’s a photo of me, so naturally the password is my full name No capitals, all one word. Have fun!
