Information Hiding In Images Using Least Significant Bit Steganography

Steganography is an ancient practice. When spies in the Revolutionary War wrote in invisible ink or when Da Vinci embedded secret meaning in a painting that was steganography. Steganography is an encryption technique that can be used along with cryptography as an extra-secure method in which to protect data This book presents a detailed exposition of one of the simplest technique of covert communication in an extremely simple language. Least Significant Bit Embedding are a general steganographic technique that may be employed to embed data into a variety of digital media but one of the most studied applications is using LSB embedding to hide one image inside another. This book focuses on Least Significant Bit embedding with grayscale images. The concept of understanding by example and experimental result has been stressed throughout the book.
