2018年8月12日 · This article details a common steganography method known as the Least Significant Bit. This technique is very efficient because of its simplicity and its ability to be undetectable to the naked eye .

LSB - Least Significant Bit. This method is the simplest method of digital image steganography. The method consists in replacing the least significant bits of the container image with the bits of the message. The logic of the method can be illustrated by the following picture

2020年9月1日 · In this article you will learn how the LSB (Least Significant Bit) method works and how to use the PyLSB software to read and write secret messages in the pixels of an image. Steganography is...

2021年12月12日 · LSB stands for Least Significant Bit. The idea behind LSB embedding is that if we change the last bit value of a pixel, there won’t be much visible change in the color. For example, 0 is black. Changing the value to 1 won’t make much of a difference since it is still black, just a lighter shade.

It can be safely claimed that the image steganography quality is significantly improved through LSB via enhanced PSNR (Peak Signal-to-Noise Ratio) and MSE (Mean Square Error). However, the size and secrecy of secret data is the biggest challenge while applying LSB techniques.

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. Keywords— Steganography, data-hiding

2022年3月11日 · Least significant bit (LSB) insertion is a common and simple method to embed data in an image file. In this approach the LSB of a byte is restored with an M’s bit. This technique operate well for image steganography. For hiding data within the images, the LSB (Least Significant Byte) approach is generally used.

2017年10月29日 · This paper reviews the method of steganography based on Least Significant Bit Substitution of digital image and analyzed pattern of LSB substitution which hides the message in the form of bits. The pattern of LSB are categorized into Bitwise and Blockwise and then again classified further into linear and nonlinear.

2021年2月8日 · We can divide the LSB-based steganography methods into two categories: LSBR (LSB replacement) and LSBM (LSB matching). LSBR simply replaces each bit of the secret message into the lowest bits in the cover image.

Least Significant Bit (LSB) embedding is a simple strategy to implement steganography. Like all steganographic methods, it embeds the data into the cover so that it cannot be detected by a casual observer.
