Text with Image Editing Using Steganography

Abstract

“Editing Text With Image Steganography” is the software developed for hiding information which uses the technology called as steganography, which is the art of hiding information in ways that prevent its detection. A message in cipher text may arouse suspicion while an invisible message is not. The conventional way of protecting information was to use a standard symmetric or asymmetric key system in encryption. Steganography can also be used to place a hidden “trademark” in images, music, and software, a technique referred to as watermarking. Steganography, if however used along with cryptography then the message will become quite secure as far as cryptanalytic attacks are concerned. Now, if this cipher text is embedded in an image it is even more secure. If an encrypted message is intercepted, the interceptor knows the text is an encrypted message. With steganography, the interceptor may know the object contains a message. Data hiding is a technique that conceals data into a carrier for conveying secret messages confidentially. Digital images are widely transmitted over the Internet; therefore, they often serve as a carrier for covert communication. Images used for carrying data are termed as cover images and images with data embedded are termed as steganography images. The least significant bit substitution method, referred to as LSB.
