Steganography consists of concealing one message within another message. It is a good way to send documents anywhere in the world over the internet without needing to encrypt the documents. The operation consists of attaching a RAR archive to a JPEG image and thus, the documents are no longer visible to everyone. Your files remain protected as long as no one knows that there are files attached to the image and the image is no different from any other image. It's a quick and easy way to secure access to documents you might email or share on an online server.
