This cluster focuses on the application of security techniques to protect data in its various guises as it is stored, transmitted, processed and archived by a variety of applications and systems for the full range of business purposes. The value of business and personal data is becoming increasingly recognized and this cluster covers the use of cryptographic and other means to protect data in a way which supports the business function and usability of relevant software applications.
Secure Communities of Data Sharers
This is an application of digital rights management technology to control the sharing of digital media within a community.
Universal XML Data Exchange Software
This software provides a bridge between relational database schema and XML. It allows XML documents to be generated and exported from a relational database, and the schema can be customized using a GUI. Similarly XML documents can be imported into a relational database without programming.
Data Recovery Suite
Tools to recover data from damaged memory cards and hard disks including deleted and corrupted files.
XML Visualization Framework
A software suite which facilitates the use of XML as an intermediate format to represent data in new visualization tools
Secure Outsource Database technology
A method to allow encrypted documents, stored remotely, to be efficiently searched without being revealed to the storing party. A key technology for secure out-sourcing of data.
Trust Extension Device
A USB based virtual computer to protect the mobile user from threats on temporarily used machines.
Secure Preservation of Digital Data
A PKI based system to provide secure archiving of digital repositories
Copy Detection Technology
This technology detects similarities in large collections of data. It has applications in plagiarism detection and copyright infringement, alterations and modifications.
Automatic Detection of Video and Film Copies Distributed on the Internet NEW
This reliable automatic detection system will assist companies in making cost savings by identifying, confirming and tracking non-authentic video film exchange over the Internet. Videos that are copied across peer-to-peer networks can be substantially altered. For example changes in spatial resolution, CODECS, colour depth and frame rates all increase the difficulty of retrieving a watermark for identification. This technology does not embed additional information in the video and automatically identifies computer derived/digital files containing copies of videos and movies. The performance is independent from CODEC, low bitrate, low frame rate, and noise artefacts.
A Fast Nearduplicate Video Clip Search Engine NEW
Near-duplicate video clip (NDVC) detection is an important problem with a wide range of applications such as TV broadcast monitoring, video copyright enforcement, content-based video clustering and annotation, etc. This system performs online NDVC detection and comprises two novel complementary schemes for detecting NDVCs. The first globally summarizes a video to a single vector which captures the dominating content and content changing trends of each clip. The second maps each clip to a sequence of symbols, and takes temporal order and sequence context information into consideration. It has emonstrated real-time NDVC detection with high accuracy.
