Steganography is the art of covered writing or hidden writing. The steganography can be done in six types of techniques, namely: substitution system technique, transform domain technique, spread spectrum technique, statistical method technique, distortion technique and cover generation technique. This paper deals with substitution system technique and transforms domain technique. This paper deals with four methods of steganography, namely: plain LSB steganography, inverted LSB steganography, pattern based steganography and two-sided, three-sided, four-sided side matched methods steganography. The performance and evaluation of these methods are done in the following sections.
