What is steganography and how it works?

Steganography works by hiding information in a way that doesn’t arouse suspicion. One of the most popular techniques is ‘least significant bit (LSB) steganography. In this type of steganography, the information hider embeds the secret information in the least significant bits of a media file.

How do you implement steganography?

A Steganography system consist of an embedding process and an extracting process. A stego image is produced in the embedding process while a cover image and secret message will be required as input. To hide the secret information, the pixel of the cover image will be secretely chosen with a stego key.

What is LSB steganography?

The Least Significant Bit (LSB) steganography is one such technique in which least significant bit of the image is replaced with data bit. As this method is vulnerable to steganalysis so as to make it more secure we encrypt the raw data before embedding it in the image.

What are the types of steganography?
