Modern technologies have eased the way for adversaries to bypass the conventional identity authentication and identification processes; hence security systems have been developed to a great extent for protection of privacy and security of identities in different applications. The focus of this thesis is digital watermarking, security and privacy, as well as the ability to employ electrocardiogram as a method to enhance the security and privacy level. A high capacity reversible multiple watermarking scheme is introduced to mainly target the medical images. Furthermore, the use of ECG biometric signals in the form of the embedded watermark is studied. Experimental results indicate that the reversible data hiding scheme outperforms other approaches in the literature in terms of payload capacity and marked image quality. Results from the ECG mark embedding also show that no major degradation in performance is noticeable compared to the case where no watermarking is needed.

Generating employee rosters on a 24 hour, 7 day per week basis taking into account fluctuating demand for employees, employee skills, working conditions, training and employee preferences, while ensuring efficiency and equity between the employees is a very difficult task due to the very large number of possible rostering combinations available. The research done in this thesis sets to solve this exact problem for CS Energy's Swanbank Power Station located in Queensland, Australia. / thesis (PhDMathematics)--University of South Australia, 2002.
