Cloud storage is a becoming a preferred method for storing data, largely owing to its cheapness, scalability and flexibility.  Individuals and companies utilize data from public cloud storage repositories knowingly or ignorantly.  However, recent events have shown that data outsourced to the public cloud providers cannot be assured of privacy and security, unauthorized  access to data can be made from several  sources including untrusted providers, government security agencies or other malicious third parties.  This has an undesired affect on the adoption of cloud storage and creates a choice for other similar options which are usually more expensive like private cloud storage.

The focus of the seminar is to design and develop innovative approaches for securing public cloud storage. Current seminar topics focus on the field of secure authentication and device management.


Programming skills in Java are desirable, also students may benefit from previous experience of the lecture "Internet Security".

Lern- und Lehrformen

This seminar is focused on practical work. Students will familiarize themselves with the topic "Privacy in Public Clouds" and develop ideas to solve specific given challenges. The main part of the seminar will be design and implementation of a suitable solution. Finally, students will be expected to present their results and submit a technical report. The bulk of seminar sessions will be dedicated for group work with provision for physical meetings with the tutors


The final evaluation will be based on:

  • Concept development & presentation: 10%
  • Implementation: 50%
  • Result presentation: 20%
  • Report/Documentation: 20%


After two to three introductory sessions meetings will happen on demand rather than on a weekly base.
