## What is least significant bit in steganography?

Least Significant Bit steganography is one such technique in which least significant bit of pixels of the image is replaced with data bits. This approach has the advantage that it is simplest one to understand, easy to implement and results in stego-images that contain embedded data as hidden.

### What is the least significant bit algorithm?

The Least Significant Bit Replacement algorithm is a com- monly used straightforward steganographic algorithm, which is used to embed secret message inside a cover medium. In this method, the secret message is stored in the least significant bits of the original cover image and the bits are flipped accordingly.

How do you do steganography in Matlab?

Traverse through each pixel of the image and do the following:

1. Convert the pixel value to binary.
2. Get the next bit of the message to be embedded.
3. Create a variable temp.
4. If the message bit and the LSB of the pixel are same, set temp = 0.
5. If the message bit and the LSB of the pixel are different, set temp = 1.

What is least significant bit in image?

5.1 Least significant bit algorithm Least significant bit (LSB) insertion is a common, simple approach to embedding information in a cover image [12]. The least significant bit in other words, the 8th bit of some or all of the bytes inside an image is changed to a bit of the secret message.

## What is steganography in MATLAB?

LSB Substitution Steganography MATLAB Implementation. Basically there are main four mediums in which steganography is to be carried out. These four mediums are Text, Image, Audio/Video and Protocol. Image stegnography plays important role in stenographic field.

### What is LSB substitution in steganography?

Steganography using LSB substitution. The basic concept of LSB substitution is to embed the confidential data at the rightmost bits (bits with the smallest weighting) so that the embedding procedure does not affect the original pixel value greatly.

What are the different mediums used in steganography?

Basically there are main four mediums in which steganography is to be carried out. These four mediums are Text, Image, Audio/Video and Protocol. Image stegnography plays important role in stenographic field.

What is the LSB value of a grayscale image?

In a grayscale (black and white) image, these pixel values range from 0-255, 0 being black and 255 being white. LSB stands for Least Significant Bit.
