Abstract
In this paper, a new methodology is used to preserve confidential information (for e. g. If we like to preserve an information which is in image form i. e. confidential image) which is a blue channel replacement technique, in order to hide maximum amount of data in an image without degrading its quality. In the proposed technique, the emphasis is placed on maximizing the embedding capacity and imperceptibility. Finally, the performance of the scheme is evaluated by using performance metrics such as Peak Signal to Noise Ratio (PSNR), Root Mean Square Error (RMSE). Several experiments have been performed and have been compared and it has been observed that the RMSE is inversely proportional to PSNR from the results obtained with the already existing schemes.
