الملخص الإنجليزي

Steganography is the art of concealing messages or information within other non-secret text or data.

Various steganography techniques have been proposed in literature.

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 exposed to steganalysis, efforts are being put together in order to make it more secure.

This study propose a new technique for image steganography, that uses the Least Significant Digit (LSD) to store text data inside colored images, each character is presented using its ASCII code which is made of three digits, the proposed technique use the RGB values of each pixel which enhance the ability of storing more data than previous known techniques, the embedding is achieved by replacing the LSD of each color of the pixel by a digit of the character ASCII representation, the results show that the value of colors effect the amount of data one is able to store in the image, the obtained results of the proposed study shows that the use of encryption in steganography using the proposed method does not affect the image quality.

It is also worth to mention that the storage capacity is better than LSB and DCT.
