Novel Steganographic method for Encrypted Image as a cover media for Binary image, Text and Audio

Abstract: Data hiding is an important branch of information security. Imperceptibility and Hiding Capacity are very important aspects for efficient secret communication. In this paper we propose a Steganographic method for encrypted image. In this method our aim is to embed the data like binary image, Text and Audio file in encrypted cover media. This method first encrypts the Cover media with encryption method and after Encryption secrete data can be embedded into the Encrypted cover object by modifying a small proportion of Encrypted data. PSNR (Peak Signal to Noise Ratio), EC (Embedding Capacity) and NBE (Number of Bits Embedded) these three are the quality parameters.

Keywords: Steganography, Encryption, Data hiding, Secrete Communication.
