English Abstract

Steganography is defined as a science of concealing the secret information within several different carriers.

Due to the web images widely used as a carrier for hiding the secret information, and the increased demand of the security level for sending secret information securely at different levels, image steganography became a significant filed in the steganography science.

But it extremely became vulnerable for many different attack types.

This paper will present a new method for hiding messages in 24 bit BMP images using LFSR-based stream cipher technique.

The proposed algorithm depends on the least significant technique (LSB).

LFSR generated-sequence will be used for encrypting the message bits, and then three encrypted bits will be hidden per pixel.

This method got high quality ; since the naked eye can’t distinguish between the cover image and the stego image.

Also it is a secured method ; according to the RS analysis (which depends on the difference between the bits or pixels between the stego-image and original one) results of this proposed method comparing to other results obtained with different steganography tools.
