Steganography of Confidential Information in Digital Images Based on Fuzzy Edge Detection

Steganography is the science of invisible telecommunication. This science aims to provide secure and inconspicuous communication. In fact, a steganography system should hide a confidential message in a media medium (voice, image, video, etc.), such that no tangible change is made in the media and the unauthorized eavesdropper of the channel (attacker) cannot notice the existence of hidden information. Steganography is the art and science of information embedding in a media medium with an increasing application considering digital communications. The main objective of steganography is security in the lack of proving the existence of a message. Most existing methods use common image steganography approaches, where attacks are discussed for decrypting the hidden message. Therefore, this paper provides a method based on fuzzy edge detection to embed information in digital images. Results of the proposed method show the high quality of the steganography image.
