Data systems and cyber security

Flagship leaders

This flagship encompasses research into innovative data management, storage and indexing techniques as well as addressing the challenge of keeping data secure in the rapidly changing and increasingly online data ecosphere.

The ability to capture, analyse and utilise data is crucial to decision making on many levels. The proliferation of mobile devices, sensors and social networks has led to the generation of massive amounts of data about individuals, groups of individuals and organisations. Besides having to deal with  this deluge of data in terms of storage and efficient access, current data systems must also deal with new types of data analysis. Both challenges require re-thinking of the way data management systems should be developed. In addition, the adoption of online computing services and communication devices  in recent years has brought with it a wide variety of security challenges, from privacy violations through to financial fraud and service interruptions. These challenges have been aggravated due to the lack of effective technologies for enforcing security without compromising the convenience of use of  online services.

The flagship currently incorporates, amongst others, projects in high performance databases, spatial data management, information retrieval, cryptographic technologies, information forensics, network security and biometrics.

Research themes

The major research themes that the flagship operates under are as follows:

Data systems

  1. Research and develop technology that supports data analytics at large scale for industry and research community.
  2. Research and develop technology for individual data capture, analysis and visualisation of individual data from mobile device and sensors.
  3. Development and investigation of the application of innovative data system solutions to a specific industry and/or research problems.


Research and development of technology that:

  1. Provides robust authentication and identification in uncontrolled environment with pervasive devices and limited special infrastructure
  2. Ensures information privacy, integrity and robustness to users of information and communication technology
  3. Leverages today's online, mobile and cloud-based computing infrastructure
