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
Approximate authentication systems for digital information. Assurance about the origin and integrity of digital content is crucial not only in high security applications but also in everyday life scenarios such as providing proof that an X-ray image presented as part of an insurance claim is authentic, or a news clip is not tampered with. The outcomes of this project will significantly enhance trustworthiness of multimedia information systems which are increasingly used in areas such as surveil ....Approximate authentication systems for digital information. Assurance about the origin and integrity of digital content is crucial not only in high security applications but also in everyday life scenarios such as providing proof that an X-ray image presented as part of an insurance claim is authentic, or a news clip is not tampered with. The outcomes of this project will significantly enhance trustworthiness of multimedia information systems which are increasingly used in areas such as surveillance (traffic control), health, digital content production and distribution, tourism and journalism. It will also result in the development of secure biometric authentication systems which are critical in securing cyber space.Read moreRead less
Information security and digital watermarking with Latin squares. The importance of digital information is increasing constantly. Audio, video, and still image data dominate our daily lives. Such information has commercial and strategic importance. It is invaluable in crime prevention: for example, video from security cameras. The protection of commercially valuable material against piracy and sensitive information against security breaches is vital to our economy and our safety. This project ad ....Information security and digital watermarking with Latin squares. The importance of digital information is increasing constantly. Audio, video, and still image data dominate our daily lives. Such information has commercial and strategic importance. It is invaluable in crime prevention: for example, video from security cameras. The protection of commercially valuable material against piracy and sensitive information against security breaches is vital to our economy and our safety. This project addresses these issues, by developing new, secure watermarks and fingerprints to protect digital information. Such watermarks can also protect radio communication channels, which is important due to the rising demand for wireless connectivity.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.
