Abstract

Steganography has found its value for a long time in digital transformation/ communications. Cryptography is the oldest method to convert a plain text into cipher text. Steganography is the art of encryption. For example, a picture is used to cover details. Steganography in the local domain plays a major role because of its compatibility with images. Steganography is a study of undetectable communication that regularly deals the methods to hide the details of existence. Normally, secret data are embedded into a text message, image, voice, audio and video. Steganography is a process of embedding private information or a message into an image commonly referred to as stego-image (image with hidden message). This paper reviews books on various forms of steganography images in the local domain for the past 5 years. The main purpose of this paper is to study the methods and its findings along with their advantage and disadvantages of existing steganography techniques. The complete configuration of steganography techniques for buildings and their structures in the local domain is reduced. Researchers have already done a lot of research on image steganography but the embedded methods may be incomplete. In this article we have explored many steganographic methods in the local domain. This paper examined various steganographic tools and covered steganography summary in its main types, classification and applications.  This paper discussed various steganographic tools and techniques.  Also it covers the steganographic general ideas including the impacts and applications.
