English Abstract
The method of steganography means the ability of hiding data inside a cover.
Steganography helps to hide data in another of a different type , and thus it can guarantee a high degree of security.
Previous studies proposed many algorithms that hide text inside colored images, some of these the algorithms depend on hiding data directly in a special domain.
There are other algorithms that depend on changing the image shape into another using discrete cosine functions (Transform domain techniques ).
The study proposed a new improved technique that takes the advantage of the 24 bits in each pixel in the RGB images and hiding data directly in a special domain, using the two least significant bits of red channel to indicate existence of data in the other two channels which are green and blue.
The number of bits which will be embedded in the right part are counted in the lift part of the channel which chosen for embedding.
This algorithm is characterized by the ability of hiding larger size of data and the data were embedded inside the image randomly in a new randomization technique which gave the message a higher security and resistance against extraction by attackers.
This algorithm has been compared with other known algorithms and the new results proved the power of the new algorithm to hide and extract data.
