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
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

Credential Systems and Their Applications in Securing Electronic Health Records. The expected result of this project will be frontier technologies that are essential in applications and services, whose acceptance and take-up will depend on users' assurance of their security in the cyber world. In particular, a service such as the EHR system, which is known to be a complex system, requires the use of new and innovative credential-based systems. The result will also contribute to maintaining Austr ....Credential Systems and Their Applications in Securing Electronic Health Records. The expected result of this project will be frontier technologies that are essential in applications and services, whose acceptance and take-up will depend on users' assurance of their security in the cyber world. In particular, a service such as the EHR system, which is known to be a complex system, requires the use of new and innovative credential-based systems. The result will also contribute to maintaining Australia's leading position in the telecommunication and information technology industries, which has been recognised by increased government funding levels. The resulting applications of this project will place Australia as the first country able to design and implement a secure EHR system.Read moreRead less

The expected results of this project will be frontier technologies that are essential in applications and services whose acceptance and take-up will depend on users' assurance about their security in the cyber world. The project will contribute to the economic and social advancement of Australia by allowing effective usage of advanced IT technologies. This development will also maintain Australia's leading position in the telecommunication and IT industries, which is well recognised by increasing levels of government. The resulting application will place Australia as the first country able to design and implement a provably secure and practical e-payment system.Read moreRead less
Secure and Dynamic Single Identification Systems. The expected results of the project will be frontier technologies that are essential in applications and services whose acceptance and take-up will be dependent on users' assurance of their privacy. Services, such as medical information or bank information, require a secure identification scheme. Securing such services will encourage new forms of collaboration among a wider range of users with the likely impact of a more productive global economy ....Secure and Dynamic Single Identification Systems. The expected results of the project will be frontier technologies that are essential in applications and services whose acceptance and take-up will be dependent on users' assurance of their privacy. Services, such as medical information or bank information, require a secure identification scheme. Securing such services will encourage new forms of collaboration among a wider range of users with the likely impact of a more productive global economy. This impact will be particularly emphasised in Australia with its geographically disperse population. Securing vital electronic transactions will ultimately contribute to lowering costs and increasing productivity and so creating a more competitive economy.Read moreRead less

Using provably secure short signature schemes in the Internet world will ultimately contribute to lowering costs, increasing productivity and therefore, a more competitive economy. The project will produce high quality graduates by generating research opportunities for students.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.

Working, socialising, establishing commercial and government institutions on the Internet, is rapidly becoming a common way of life. Digital signatures are the main mechanism for providing authentication and accountability for electronic transactions, and are indispensable in securing electronic exchange and collaboration. Existing digital signatures only provide security for a limited time period and cannot be used when long term security is required. This project will provide the required foundations and construction for building a timeless `trustworthy cyberspace' and will enable deployment of a wider range of advanced information technology and telecommunication services.Read moreRead less
