摘要：A multiple, fragile image authentication scheme is proposed for DICOM images using discrete wavelet transform. This scheme addresses critical health information management issues, including source authentication, data authentication and transfer of patient diagnosis details. The robustness of the method is enhanced through a form of hybrid coding, which includes repetitive embedding of BCH encoded watermarks. The watermarked images were tested with common attacks to evaluate the behaviour of the algorithm. Conclusions were drawn based on the algorithms performance when the images were subjected to various attacks. The algorithm was also tested by changing the wavelet function used in the algorithm and the results show that the Haar wavelet is the most suitable wavelet. The experimental results on different medical images demonstrate the efficiency and transparency of the watermarking scheme, which fulfils the strict requirements concerning the acceptable alterations of medical images.
