A Novel Approach for Reversible Data Hiding in Encrypted Images Using Key Based Pixel Selection
Journal Title: International Journal of Computer Science & Engineering Technology - Year 2014, Vol 5, Issue 6
Abstract
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. The basic idea in the newly proposed method is to embed the data into the least significant bits of pixels of red plane which are placed diagonally within the cover image. Replacing the Least Significant bits in a single RGB plane does not provide any distortion to the restored image which can be visible to human eye.
