Efficient and secure data integrity auditing on cloud

数据审计为验证云上用户数据的完整性提供了一种很有前景的方法，即验证云上用户身份信息等隐私敏感数据是否被修改或丢失。目前的审计方法缺乏足够的效率和安全性。这导致它们无法对潜在的数据丢失威胁提供及时的警告和预防。该项目旨在系统地调查这一重大挑战，并期望建立创新的研究和解决方案，以实现高效和安全的云数据完整性审计。项目成果将有助于在快速发展的网络世界中保护澳大利亚社区，并有利于快速增长的用户隐私敏感数据托管和云应用程序。

Data auditing presents a promising way for verifying user data integrity on cloud, i.e., whether user privacy sensitive data such as identity information on cloud is modified or lost. Current auditing approaches lack sufficient efficiency and security. This results in that they cannot provide timely warning and precaution on potential data loss threats. This project aims to systematically investigate this significant challenge and expects to establish innovative research and solutions for enabling efficient and secure data integrity auditing on cloud. The project outcomes will help to safeguard Australian community in fast-growing cyber world, and benefit to fast-growing user privacy sensitive data hosting and applications on cloud.
