A novel API and associated algorithms will be developed to exploit the emerging technology of software defined networks (SDN) for improving the efficiency and responsiveness of interactive media browsing applications. The approach applies to conventional streaming video as well as more interactive services based on scalable media compression and communication technology, notably JPIP (IS15444-9) video. Recent advances in motion coding will be combined with new spatio-temporal transforms to develop an efficient inter-frame extension to the JPEG 2000 standard that is fully compatible with JPIP. Each of these innovations is important in its own right, but together they will facilitate a highly compelling interactive media browsing experience.Read moreRead less

Applications for large format video surveillance are about to grow rapidly, starting with military applications and then moving into the civilian arena, highlighting the importance of compression for interactive dissemination, so as to make best use of limited communication channels. This project will develop an innovative representation for motion and depth/elevation maps, which addresses a key obstacle in the deployment of technology for efficient interactive access to large format video and geospatial imagery. These applications are relevant to Australia's defence and infrastructure for smart information use. Moreover, this is a strategic proposal to strengthen Australia's existing lead in aspects of interactive media dissemination.Read moreRead less
Security Techniques against Denial of Service Attacks in Networked Systems. As more and more business opportunities are created over the Internet, dealing with network-based intrusions and denial of service (DoS) attacks is becoming increasingly critical (as witnessed recently last year).

As more and more business opportunities are created over the Internet, dealing with network-based intrusions and denial of service (DoS) attacks is becoming increasingly critical (as witnessed recently last year). The proposed research addresses systematically the theory and analysis of DoS attacks and develops new techniques and practical solutions to counteract them. We will investigate a hybrid method to counteract DoS, propose a new technique to identify malicious packets in the Internet to handle distributed DoS, consider a new approach using smart packets and develop enhancements to intrusion detection systems using data mining. Proposed techniques are analysed in practical situations.Read moreRead less
