A Review on different Patching Techniques

Abstract

Steganography is an advanced version of cryptography basically used for coding practice and for hiding private information. While cryptography provides privacy, Steganography is intended to provide secrecy. Steganography means hiding one piece of data within another. There are different types of Steganography: Text Steganography, Image Steganography and Audio Steganography. This work will focus on comparative study on major techniques like LSB, Masking and Filtering, Transformation Domain based technique, Chaffing and Winnowing, Jsteg and F5 algorithm. It will also present the best algorithm of steganography of each type.
