Module Description

Cloud storage services are extremely popular, both among companies and private users. However, the fact that with such services data is stored, transmitted and processed outside of the premises of the user, often raises concerns about data security, in terms of privacy, confidentiality, integrity, and availability.

There is an increasing tendency among the users (private or company) to find out more about their data are treated and preserve their privacy.

To help them to determine this, and cover these concerns, privacy metrics should be identified. Identifying these metrics and concerns could lead to a methodology to evaluate the data privacy regarding the user perspective on cloud services.

Corresponding evaluating and ranking algorithms could turn the public view on service providers and change the business plan.

The objective of this seminar is to perform an extensive analysis of the state of the art in which privacy concerns and threats, and the implementation of counter-measures will be identified and analysed.

Learning Goals and Competencies

  • Basic understanding of privacy threats and privacy enhancing technologies in the field of cloud services
  • Basic understanding of user perceptions of privacy
  • Basic understanding of cloud services
  • Communication of the obtained results in a clear and comprehensible manner
  • Critical discussion of all results in the group

In order to successfully pass this module, you need to write a paper (60%) and make a presentation (40%). Each partial requirement needs to be passed with a grade of 4.0 or better.

Topics are in the area of:

  • Privacy concerns in cloud data storage
  • Privacy concerns in cloud services
  • Privacy-preserving methods in cloud services
  • Adopting privacy metrics for the cloud service
  • Economic incentives for privacy-preserving Cloud service providers
  • Privacy-preserving cloud computing

Specific topics will be provided during the kick-off session before the registration. The methodologies will be presented and discussed in the group before the allocation of the topics.

Students are still required to work through the methodology of their topic carefully.
