Steganography

Steganography is the art of hiding a secret message within a normal message. This is used to transfer some secret message to another person; with this technique, no one else in between will know the secret message you wanted to convey.

This art of hiding secret messages has been used for years in real-life communications. Since the evolution of digital communication, it has also been used in digital conversations.

This secret hidden information can be a plaintext message, ciphertext or image. One can hide information in any kind of file: common choices include images, video and audio files, which can be used to hide plaintext or image messages. There are now specific tools available for this purpose.

The main reason for using steganography is that you are hiding your secret message within an ordinary file. No one will suspect the file and your secret message will go undetected. The file used to hide a message will function normally.

Secure transmission of files is often very important. Hackers are everywhere and always try to intercept communications (Read more...)
