Enhancement of Data Hiding Process in Encrypted Image Using Advanced Encryption Standard

Abstract

In this paper a scheme known as separable reversible data hiding is proposed for the secured transmission of data. This scheme uses Advanced Encryption Standard for secured data transmission. The basic technique used here is image encryption, data embedding along with data extraction and image recovery phases which uses same keys for both encryption and decryption. To make the data transmission process secure additional data is added using the data hiding key so that original data can’t be extracted without both encryption and data hiding key. The data embedding technique uses data compression which is a lossless technique creating space for the additional data to be added. This technique using the AES algorithm improves the PSNR ratio.
