How can I hide files in jpeg images?
It's a very simple trick. Just visit this link
Hide Files Inside an Image
I actually do it with a DOS Batch file / DOS commands.
- First, start with any standard jpg photo: my_photo.jpg
- Then, compress (Zip) the desired document that you want to hide into a zip file to make: my_secret.zip
COPY /B my_photo.jpg+my_secret.zip my_pretty.jpg
You end up with "my_pretty.jpg" which you can click on and it's a regular jpg photo.
If you "unzip" the "my_pretty.jpg" you get back the document that went into my_secret.zip (Note, you may have to rename the "my_pretty.jpg" into "my_pretty.zip" for your unzipper to work).
As a bonus, I use a password when I'm creating the zip file originally - which means that a person who casually extracts it - is still foiled with a password requirement.
Photo display apps ignore the zip part of the resulting file - and unzippers ignore the jpg part. There's no outside indication that this resultant jpg file is anything but a photo file.
There is a command in Microsoft DOS
If you have winrar installed it is as easy as renaming a picture to something.rar, then open it with winrar, drag your files and close winrar, then rename it back to jpeg.
$ cat >> foo.jpg < bar.txt
