Privacy-protecting Data Management in distributed Cloud Infrastructures

Abstract

Today's cloud infrastructure platforms such as Amazon Web Services (AWS) allow to deploy and run complex services without having to worry about scalability, reliability and general maintenance tasks. However, with distributed services running on multiple instances and on potentially untrusted nodes, the protection of data and in particular the preservation of privacy has become a huge challenge: On the one hand, data storage must be achieved in a way that an attacker with access to the file system, or in some use cases also the cloud operator, is not able to retrieve critical information such as personal data. On the other hand, the combination of individual data chunks to privacy critical information at runtime must be prevented when creating distributed applications.
