A Survey on various types of Steganography and Analysis of Hiding Techniques
Journal Title: INTERNATIONAL JOURNAL OF ENGINEERING TRENDS AND TECHNOLOGY - Year 2014, Vol 11, Issue 8
Abstract
Digital Steganography is the science that involves communicating secret data in an appropriate multimedia carrier, e.g., image, audio, and video files. Under this assumption, if the feature is visible, the point of attack is evident, thus the here goal is conceal to the existence of the embedded data .This is totally review paper, in which we provide the comparison of available steganography technology hiding text in an image file using Least Significant Bit (LSB) based Steganography, Discrete Cosine Transform (DCT) based Steganography and Discrete Wavelet Transform (DWT) based steganography. The LSB algorithm is implemented in spatial domain in which the payload bits are embedded into the least significant bits of cover image to derive the stego-image whereas DCT & DWT algorithm are implemented in frequency domain in which the stego -image is transformed from spatial domain to the frequency domain.
