Ruby Hazarika, Rajiv Gandhi Salai · 2013
The paper discusses about securing of data in an encrypted image. The content owner in the first stage encrypts the original uncompressed image using the encryption key. The data hider then compresses the least significant bits of the encrypted image using data hiding key to create some space to accommodate some extra data. If the receiver has both the data hiding key and the encryption key only then receiver can extract the relevant data and the image.
