An Investigation for Steganography using Different Color System

Steganographic techniques are generally used to maintain the confidentiality of valuable information and to protect it from any possible theft or unauthorized use especially over the internet.In this paper, Least Significant Bit LSB-based Steganographic techniques is used to embed large of data in different color space models, such as (RGB, HSV, YCbCr, YIQ, YUV). The idea can be summarized by transforming the RGB value of the secret image pixels into three separate components into the pixels of the cover image.
The measures (MSE, SNR, PSNR) were used to compare between the color space models, the comparisons proved that steganography with color systems (RGB and HIS) shown a best results.
