Towards full lifecycle privacy protection on cloud

云上用户数据的隐私保护在用户信息生命周期的各个阶段都存在风险，面临着阶段自适应保护、跨系统保护、隐私入侵追踪与预测等重大挑战。目前的做法主要集中在某一阶段的具体情况，因此无法通过考虑所有阶段来妥善解决这些挑战。该项目旨在系统地调查这些挑战，并期望建立创新的研究和解决方案，以实现云上的全生命周期隐私保护。项目成果将有助于在快速增长的在线网络世界中保护澳大利亚社区，并有利于快速增长的隐私敏感数据托管和云应用程序。

Privacy protection in user data on cloud is now at risk throughout all stages of user information lifecycle facing significant challenges such as stage adaptive protection, across-system protection, privacy invasion tracing and prediction. Current approaches mainly focus on a specific case at certain stage, hence cannot address those challenges properly by considering all stages. This project aims to systematically investigate those challenges and expects to establish innovative research and solutions for enabling full lifecycle privacy protection on cloud. The project outcomes will help to safeguard Australian community in fast-growing online cyber world, and benefit to fast-growing privacy sensitive data hosting and applications on cloud.
