The efficiency of Color Models layers at Color Images as Cover in text hiding

The color images are used widely as a cover in hiding of the information. Since variety applications image there several models image. Most consist three layers. nature mode plays main role determining robustness and security algorithm.
 objective this paper tests layers, components, images, to figure out which layer each model is best (less affected) use hide information within process. experiments concentrate on texts two positions layer, 7th bits 8th (LSB). Mean Square Error (MSE) Peak Signal Noise Ratio (PSNR) were measure affected hidden text done nine colors models: RGB, HSV, HIS, HSL, HSB, YCbCr, La*b*, LUV CMYK.
 results show that some have such HSI, CMYK, HSL . In other been tested, not distinctive layer. H worst because any leaves clear impact
