Securing the medical images to make it tamper free is a terribly difficult task. With the advanced digital watermarking (DWM) technique, we are able to protect the medical images by evaluating validation, dependability, privacy and integrity. The DWM is implemented in two main domains: transform and spatial. The DWM is mostly implemented using the transform techniques such as singular valued decomposition (SVD), discrete cosine transform (DCT), discrete wavelet transform (DWT), integer wavelet transform (IWT) and combination of these techniques. One of the foremost challenges in these technologies is information embedding capability and this parameter is considered for evaluation of the system. One of the possible ways to reduce the number of embedding bits in information is to use quick response code (QR). The proposed DWM system uses: IWT, bit plane and QR code.
