“…And uses the stego key for extraction the data hidden (secret image) from stego cover through use the process embedding inverse. Divya.E [5] presented hiding text message inside grayscale image using two approaches which are : Particle Swarm Optimization algorithm (PSO) and Discrete Wavelet Transform (DWT) . In the end, the researcher concluded that both these approaches gives excellent peak-signal-to-noise-ratio.…”

Because of the rapid development and use of the Internet as a communication media emerged to need a high level of security during data transmission and one of these ways is "Steganography". This paper reviews the Least Signification Bit steganography used for embedding text file with related image in gray-scale image. As well as we discuss the bit plane which is divided into eight different images when combination them we get the actual image. The findings of the research was the stego-image is indistinguishable to the naked eye from the original cover image when the value of bit less than four Thus we get to the goal is to cover up the existence of a connection or hidden data. The Peak to Signal Noise Ratio(PSNR) and Mean Square Error (MSE) value is calculated so that the quality of the cover image before and after the data hiding is evaluated.

In the case of hiding of information (Steganography), the third party does not know that there is something hidden or that is a contact between the two parties because it was used as an intermediary to hide this contact completely [2]. Related WorksOver the past years, information security has become the focus of many researchers who are trying to find new solutions, technologies and ideas that ensure the safe transfer of information through the network, especially the Internet, without interference. As a result, there are many techniques and methods currently used in information security. In this article we will highlight some ways to protect information.Vijay kumar [3] proposed a new algorithm of steganographic which is based on logical process for embedding MSB of secret image in to LSB of cover image which resulted in a significant improvement with lower computational complexity. A.S.Mahdi et al. [4]. designed proposed system is to hide image in image by using discrete cosine transformation method (DCT) and discrete wavelet transformation method (DWT) and Least Significant Bit (LSB). The system will embed the (input) secret image color inside a cover image color the secret image apply it discrete cosine transformation method (DCT) and ...
