In the area of data encryption and hiding in colour images, hackers are ready to hack the information which is to be hidden. In this concern it is very important to secure the data by using highly secured reversible data hiding and encryption techniques. The proposed algorithm proposes a new way to image encryption with reversible data hiding (IERDH) scheme with a unique private key in RGB images. A room is allocated in medical image for embedding the data by combining 2-level discrete wavelet transform and 4x4 discrete cosine transform. For any medical images, the patient details are also important to store along with actual image. So these details are imported from excel sheet, and encrypted with the help of carrier image which is generated by special key. This Cipher data image is embedded into allocated transformed image. Combine the individual components to get the transmitted medical image with hidden patient’s details. Reverse is possible to restore patient’s details from received medical image.
