Enhancing Privacy for Digital Communication. Protecting one's privacy in cyber world is a challenging task. Every contact to a Web server leaves a digital footprint that can be linked with other publicly available information to compile a profile of one's activities. Anonymous communication is a powerful tool for enhancing individuals' privacy and providing services such as electronic election where a person's vote must be unlinkable to him/her. However, anonymity may be misused by criminals to ....Enhancing Privacy for Digital Communication. Protecting one's privacy in cyber world is a challenging task. Every contact to a Web server leaves a digital footprint that can be linked with other publicly available information to compile a profile of one's activities. Anonymous communication is a powerful tool for enhancing individuals' privacy and providing services such as electronic election where a person's vote must be unlinkable to him/her. However, anonymity may be misused by criminals to hide their identities and engage in illegal activities. The aim of this project is to design and analyse privacy enhancing communication systems that balance individuals' privacy and accountability, and develop criteria and metrics to compare performance of these systems.Read moreRead less

Collusion secure fingerprinting for dynamic groups. Digital fingerprinting systems make personalised copies of digital objects by embedding a unique mark in each copy so that pirate objects can be traced to those who make illegal copies of their objects. Key fingerprinting systems use a similar approach to trace pirate decoders in paid broadcast systems such as Pay-TV. Existing fingerprinting systems do not have the flexibility that is required in advanced applications such as secure tele-col ....Collusion secure fingerprinting for dynamic groups. Digital fingerprinting systems make personalised copies of digital objects by embedding a unique mark in each copy so that pirate objects can be traced to those who make illegal copies of their objects. Key fingerprinting systems use a similar approach to trace pirate decoders in paid broadcast systems such as Pay-TV. Existing fingerprinting systems do not have the flexibility that is required in advanced applications such as secure tele-collaboration. This project develops theories and techniques that can be used for fingerprinting in these applications, hence addressing one of the most challenging problems of today's content distribution systems.Read moreRead less
Timeless digital signature for self-organising groups. Working, socialising, establishing commercial and government institutions on the Internet, is rapidly becoming a common way of life.
