This paper proposes a reversible data hiding method for supporting hierarchical control of access to data embedded in a medical image. The proposed method firstly hides the most important information to a medical image by the reversible manner in which information is enciphered. To the stego image to which once information is hidden, this method embeds different information that is enciphered with a different key. In the proposed method, only one key corresponding to the most important data is managed, and other keys are generated from the managed key through a one-way hash function. The privileged user such as the attending doctor receives the managed key and he/she extracts and deciphers all hidden data, whereas the unprivileged user like an ordinary nurse receives a key that for the least important data. The proposed method also has tamper detection ability. Simulation results show the effectiveness of the proposed method.
