In this paper the authors propose a narrative reversible data embedding system within an image which is encrypted using a public key generated by ECC algorithm. Then the data which is to be hided can be embedded into the image by modifying a fraction of encrypted data. This encrypted image containing additional data will be decrypted using the private key, and the decrypted edition is similar to the original image. According to the data embedding key, with the aid of spatial correlation in natural image, the embedded data can be successfully extracted and the original image can be perfectly recovered.
