This document summarizes a survey paper on different steganography techniques. It begins by defining steganography and its types such as linguistic, image, network, video, audio, and text steganography. It then focuses on least significant bit (LSB) steganography, explaining how it works by replacing the LSB of image pixel values with secret message bits. The paper compares the histograms of cover and stego images, showing they are almost identical. It discusses the advantages of steganography and concludes by analyzing steganography methods and suggesting areas for future work such as increasing embedding capacity while maintaining secrecy.
