A Steganographic Technique Involving Jpeg Bitstream

  Manikandan.G,  Jeya.R

Steganography is the technique of hiding secret data into a cover image, audio, text using a key which can be later recovered using the same key. The owner of the sensitive cover image cannot hide the details of the image from the data hider. A Reversible Data Hiding (RDH) technique on a compressed image is proposed along with encryption of the cover image. The cover image is first compressed. The compressed cover image is encrypted with using encryption key. The contents of the image are not disclosed to anyone without the encryption key. The data hider embeds the secret data into the encrypted cover image. At the receiver end the embedded data is extracted from the cover image using the embedding key. The cover image can be decrypted using the encryption key. The cover image can be also decrypted without extraction of the embedded data using the encryption key to produce an approximate image.
