Text image secret sharing with hiding based on color feature

The Secret Sharing is a scheme for sharing data into n pieces using (k, n) threshold method. becomes an efficient method to ensure secure transmission. Some visual cryptography techniques don’t guarantee security transmission because the secret information can be retrieved if hackers obtain number of shares. This study present with hiding based on YCbCr color space. proposed text file or image cover image. passes through three main steps: first convert and all images from RGB YCbCr, second step each band binary vector, then divide this in four-part, part appended vector variable locations, third converting space generated shares, hidden covers, are ready over network. Even get piece even all, they cannot retrieve whole picture do not know where hide information. results sending receiving any length. provides more reliability when compared others. It hides size (234x192) pixels four covers. MSE result 3.12 PSNR 43.74. shows good results, correlation between strong ranging (0.96 0.99). In reconstructed quality good, original Entropy 7.224, 7.374 respectively.
