DO YOU SEE THE DIFFERENCE?

YOU CAN'T: BUT THE ONE ON THE RIGHT
CONTAINS 32 kB OF HIDDEN DATA


It's a trick question: visually, there is no difference! But the one on the right has 32 kB of hidden data inside, even though it has almost the exact same file size as before.

These small size fluctuations happen any time you edit and re-save image file in a graphics editor. So there's no way you or anyone else can tell the difference.

Not sure yet? Try extracting the hidden data from the image.


EXTRACT HIDDEN DATA FROM THE RIGHT IMAGE


  1. Download and install Secret Layer on your computer.


  2. Download the right-hand image by right-clicking (“Save as...”) or by clicking here.


  3. Start the SecretLayer unpacking wizard (check video tutorial) or read help.


  4. Add the image you just saved and follow the steps in the wizard.


  5. Look at the message hidden in the image and open the files in any text or graphics viewer.

HOW DOES IT WORK?

Secret Layer very slightly tweaks the color of specific pixels. You can't distinguish the altered photo from the original one: even if a forensics specialist opens the image in a text editor, there's no way they can detect signs of any ”extra” information inside.



This way of hiding information is called steganography. Unlike cryptography, hiding the secret message content, steganography hides the fact of its existence. Steganography is often used with cryptography as a complement. The advantage of steganography over cryptography is that secret messages don’t attract any attention. The messages with unhidden encryption are suspicious and may be even incriminated in countries where cryptography is forbidden. In such a way, cryptography protects the massage content and steganography hides the existence of any hidden information. The most comfortable containers for data are pictures because of wide-spreading and different opportunities of transferring or publication.

ENCRYPTION IS NOT ENOUGH


Sure, you can save or send encrypted files out in the open way. Just slap a password on it and send. People do that every day. But every time you send encrypted files, you're taking a risk: you draw attention to the data inside. Prying eyes know that if you have something to encrypt, you have something to hide. It's like putting a massive lock on a suitcase and then leaving it out in the open place — people start wondering what the big fuss is for. And what if the “people” are hackers or identity thieves?



It's not enough to encrypt your documents. For real protection, you have to hide in plain sight.



Secret Layer lets you encrypt your data (so you're no worse off than before) and then hide that encrypted data in ordinary images, like the ones used every day on all websites and email attachments.

ENCRYPT AND HIDE YOUR CONFIDENTIAL DATA


The Pro version of Secret Layer supports encryption of your data:

  • Encryption type: AES, Key length: 128, 196, 256 (bits)
  • Encryption type: Blowfish, Key length: 128, 196, 256, 384, 448 (bits)
  • Encryption type: Cast-128, Key length: 40, 64, 128 (bits)
  • Encryption type: Cast-256, Key length: 128, 160, 192, 224, 256 (bits)
  • Encryption type: DES, Key length: 64 (bits)
  • Encryption type: IDEA, Key length: 128 (bits)
  • Encryption type: RC5, Key length: 64, 128, 192, 256, 384, 448, 512, 1024, 1536, 2040 (bits)
  • Encryption type: Twofish, Key length: 128, 192, 256 (bits)

  • A container with the encrypted data is hidden inside of an ordinary-looking image. This is all done automatically and in the background: you don't have to do anything extra.


    DATA TRANSFER—HIDDEN


    Any time you transfer an encrypted file to someone by email, Skype, or another method, anyone on your network can see that you're transferring something encrypted. But when you hide your data in a image, to everyone else it looks like you're uploading another photo to the web, just like billions of other people. In other words, your photo can slip away in the crowd, no different from everyone else.


    DATA EXISTENCE—HIDDEN


    To hide 1 GB of data you'll need about 5 GB of .png images.
    So how big is your photo collection? Pretty big, right?
    But if you happen to need more photos, or different photos, just use a macro. Quick and easy.
