“…Abdulaziz and Pang [55] use vector quantization called Linde-Buzo-Gray (LBG) coupled with Block codes known as BCH code and 1-Stage discrete Haar Wavelet transforms. They reaffirm that modifying data using a wavelet transformation preserves good quality with little perceptual artefacts.…”

Steganography is the science that involves communicating secret data in an appropriate multimedia carrier, e.g., image, audio, and video files. It comes under the assumption that if the feature is visible, the point of attack is evident, thus the goal here is always to conceal the very existence of the embedded data. Steganography has various useful applications. However, like any other science it can be used for ill intentions. It has been propelled to the forefront of current security techniques by the remarkable growth in computational power, the increase in security awareness by, e.g., individuals, groups, agencies, government and through intellectual pursuit. Steganography's ultimate objectives, which are undetectability, robustness (resistance to various image processing methods and compression) and capacity of the hidden data, are the main factors that separate it from related techniques such as watermarking and cryptography. This paper provides a state-of-the-art review and analysis of the different existing methods of steganography along with some common standards and guidelines drawn from the literature. This paper concludes with some recommendations and advocates for the object-oriented embedding mechanism. Steganalysis, which is the science of attacking steganography, is not the focus of this survey but nonetheless will be briefly discussed.

“…[50] [51] [52].Abdulaziz and Pang [53] is of the view that when the quantization vector is used it is said to be LBG (Linde Buzo Gray) which is paired along the block codes commonly called BCH code and 1-stage discrete Haar wavelet transforms. It is also established fact that data transformation with wavelet transform saves some better quality along with the perceptual aretfacts.…”

For hiding information in a digitalized object Steganography is an important technique. It is a special kind of scientific technique which involves the secret information communication inside suitable cover objects of multimedia like image files, audio or videos. The embedded data and its existence are hidden with the help of Steganography. It is a method of hiding data which has enormously improved the security level of confidential data with the help of special hiding mechanism and is considered as remarkable achievement in the computational power. The main aims of Steganography are; capacity of concealed data along with its robustness, lack of detection etc. These are some of the additional features which make it distinguishing from other older techniques like watermarking as well as cryptography. In this research paper, we have surveyed Steganography of digital images and cover the basic and key concepts. In spatial representation the development of image Steganographic methodology in the format of JPEG, along with that we will also debate on the modern developments as far as Steganography is concerned. For increasing Steganographic security, specifically used approaches are shortlisted and the developments made after investigations are also presented in this paper.

“…In this domain various algorithms are Li and Wang steganography [5], McKeon 2DdiscreteFourier transform (DFT) based steganography [44], Jsteg for jpeg images [6,7], OutGuess [8], -F5''algorithm [9]. Besides some DWT based techniques like W.Y.Chen, Color image steganography scheme using set partitioning in hierarchical trees coding [11], Abdulaziz and Pang technique based upon vector quantization called Linde-Buzo-Gray (LBG)coupled with block codes known as BCH code and 1-stage discrete Haar wavelet transforms [12] are certain wavelet based steganography techniques. The DWT-based embedding technique is still in its infancy.…”
