Those include ‘security through obscurity,’ and ‘out of sight, out of mind.’ Here’s a clever way to employ steganography to hide a file inside an image or photo. The process is very simple, too.
Mission Not Impossible
Steganography is the art of hiding a message, file, or image within another message, file, or image. Steganos is greek for ‘covered, concealed, or protected.’
For Mac users who have messages or documents or files they want to hide, Outguess is the app that does the deed.
The whole process of embedding the file or document in a photo or image is straightforward enough. Select the image or photo in Outguess. That’s called the ‘container.’
Then, select the file or document or text you want to hide. That’s called the ‘content.’
Click the Hide button.
Outguess then embeds the file into the code of the image so all you can see is the image or photo.
Extraction of the file or document from an image works much the same way.
Select an Outguess image from the extract panel in Outguess. Type in the secure key in the extract panel, and click the Extract button.
That’s it. The file or document is saved on your Mac.
Preferences are nominal but useful, including the keys needed to extract, JPEG image quality, and more, but the process couldn’t be much simpler. There’s plenty of security built in to Outguess, especially considering the 99-cent price tag, but I would like to see an easier way to manage the security keys used to extract files from a photo.
