The contributions are divided into two categories namely in spatial domain and frequency domain. Steganographic approaches described fall under single bit, two bits, three bits steganography both in spatial and frequency domains. Processes are illustrated and applied in various ways, providing a comprehensive understanding of the topic. The algorithmic design of the methods leads to a model towards end of the materials.
