Abstract
Steganography is the art of concealing security data in media, such as pictures, audio, video, text, and protocols. The objective of this paper is hiding a secret message in a colour image to prevent an attacker from accessing the message. This is important because more people use the Internet all the time and network connections are spread around the world. The hidden secret message uses two general algorithms that are embedded and extracted. This paper proposes a new algorithm to conceal a secret message in a colour image in LSB. This algorithm includes three phases: 1) dividing the colour image into a number of blocks, 2) concealing the secret message, and 3) transmitting the stego-image from the sender in a multiplexer network and receiving it through a demultiplexer network using an electronic workbench. The outcome of the new algorithm demonstrates good efficiency, high security, and robustness and is executed quickly. The system is evaluated through the measurements of mean square error, peak signal-to-noise ratio, correlation, histogram, and capacity.

The frame relay is used to join local area networks (LAN), and it is not executed in a single area network, whereas the data in ATM are within a single LAN
This paper describes a proposed system to hide a secret message inside a block image using LSB
Summary
Steganography is the art of concealing security data in media, such as pictures, audio, video, text, and protocols. The information-hiding method is an innovative kind of mystery communication technology It comprises embedding data into digital media (image, video, audio, text, and protocol), with a minimum appreciable declination in the steward signal, for the objectives of identification, controlling access to digital media, and copyright [4]. Facciolo et al (2014) suggested integrating image impersonation, which is a wonderful idea that allows one to evaluate the sum of picture values in rectangular areas of the image for four processes, regardless of the volume of the areas It was first suggested under the name of the “summed region table” in the Computer Graphics Society to efficiently change textile maps. Shirur (2018) suggested a wireless criterion frame status that is executed for time-critical signals (voice and video) and datum signals based on user priority in version 802.11 This proposed action is designed in such a way that forthcoming data are prioritised and integrated into Ethernet frames by tagging. The word “steganography” comprises two words of old Greek origin: steganos, which means „covering, concealed, or protected‟ and graphical, meaning „lettering‟ [14]
