|
In the proposed work the theme is separable data hiding into encrypted compressed image without any error and without degrading the quality of natural image. In the first phase, the original image is encrypted using standard image encryption technique. Then, a data-hider uses vector quantization algorithm to embed secrete data. In the second phase, with an encrypted image containing embedded data, if a receiver has the data-hiding key, he can extract the only embedded data though he does not know the image content. If the receiver has encryption key, he can decrypt the received encrypted image to obtain an original image, but cannot extract the embedded data. If the receiver has both the data-hiding key and the encryption key, he can extract the embedded data as well as recover the original image without any error. |
