A Steganography Model Based on Least Significant Bit Algorithm for Hiding Text Data in Digital Files

Steganography in the modern-day sense of the word usually refers to information or a file that has been concealed inside a digital file. With the rise of the Internet, one of the most fundamental factors is the security of information. It involves communication taking place without being known, by providing a method of writing hidden information in such a way that no one, apart from the sender and intended recipient, suspects the existence of any information/obscurity. This is the reason why in the encoding process, steganography tends to replace this redundant data with the secret message. Thus, this paper was enhanced and a new LSB algorithm developed in which it came out with a better result for the quantity of data hidden (Stego image). The paper was evaluated by using Least Significant Bit (LSB) algorithm, providing promising results in terms of quantity and image quality.
