الملخص الإنجليزي

This study presents a steganography technique to hide secret text inside color image, by using the principle of LSB, where the secret text is hidden in the least significant bits of the pixels, with more randomization in selection of the pixels used.

Two kinds of stego key were presented, the first part is a predetermined pattern which can be generated from an image, and the second is the color histogram of 128 color.

The image will be partitioned into segments of a predefined size, then the color histogram will be calculated for each segment separately.

Both keys are used to control the embedding and extracting processes.

This technique is applied to RGB images of BMP format.

The advantages of the proposed technique can be summarized as follows, perceptibility on stego image and its histogram.

High statistical image quality measurements, i.e.

higher Peak Signal to Noise Ratio (PSNR) and lower Mean Square errors (MSE) prove that the proposed technique has good quality of the stego images.

Also it is highly acceptable by the human visual system HVS.

Relatively high data hiding capacity, comparing to some other random selection based techniques.

The stego key space size is very large.

Which is hard to detect by brute force attack, thus the level of security for the proposed technique will be increased.
