Steganography in the Best of the Web Directory


Top / Computers / Security / Steganography

Steganography is a form of security technology that hides a message within an image, audio, video, or other files. The objective is to send a message within a seemingly unimportant message or something that does not attract attention. While encryption prevents others from reading an encrypted file, steganography does not necessarily require decoding or decryption (similar to what is needed in encrypted messages) through it may include a password or a steganographic coding inside of a transport layer. This security method only conceals messages, eliminates suspicion, and is considered to protect both messages and the communicating parties. It is also an alternative security solution in countries where encryption is illegal.
