摘要

In the new era of technology, more attention is needed to be given to hide some personal data or secret information, etc. This can be exactly brought out through Reversible Data [1] Hiding, since it maintains the splendid property that the original cover can be retrieved back after data is embedded. It can be extracted while protecting the image content confidentially. We suggest a new method by method of encryption after appropriating room with a conventional method. The proposed method can achieve real concealment, that is, data revealing and image recovery with some loss in data. If the receiver has the encryption key, he/she can decrypt the data to obtain an image similar to the original, but cannot extract the extra data. Experiments show that this method can embed more number of times as large number of data for the same image quality as the conventional methods, such as for PSNR & MSE.
