Steganography technique for embedding a variety of binary images inside a grayscale image

الملخص EN

Because of the rapid development and use of the Internet as a communication media emerged to need a high level of security during data transmission and one of these ways is "Steganography".

This paper reviews the Least Signification Bit steganography used for embedding a variety of related binary images in a single grayscale image rather than traditional methods of embedding information which is embedded one image in another image (cover image).

First three images represent the secret images which are used for hiding from unauthorized users while other images used for making more difficult and more secret watermark.

In this paper, we have merged both methods of hiding and watermark.

Instead of either creating a watermark or hiding secret data in a grayscale image, we can use both of them at the same image to take advantage of both the hiding and watermark properties at the same time.

The findings of the research were the results as a new watermark composed of multiple related binary images and hidden secret multiple binary images inside.
