Discrete pascal transform-based authentication schemes for DICOM images

With the prolific evolution of biomedical images acquisition from the analogue days to its current digital form, it is vital that the security of these images remain uncompromised. However, with widely available powerful digital image editing software, these images may fall vulnerable to untraceable modification leading to undesirable implications such as insurance and forensic fraud. This thesis highlights the relevance of watermarking in providing authentication for Digital Imaging and Communications in Medicine (DICOM) biomedical images in the Discrete Pascal Transform (DPT) domain. Three experimental schemes were proposed and their potential capabilities in digital biomedical media authentication applications are discussed in this thesis.
