In this paper a new steganographic approach is proposed to increase the confidentiality of the hidden data in RGB images by placing the data randomly across the encrypted images. By using the secret key provided to the users, key based pixel selection approach is applied in order to randomize the pixel selection. In order to make the retrieved image and data free from error, space is reserved before image encryption. LSB replacement method is used to embed the data in the encrypted image.
