Upon completion of the module the students are expected to be specialists in understanding the issues around privacy in computer systems and on-line services; aware of the best available techniques for mitigating important privacy threats through appropriate security and cryptography controls, namely the use of private communications, private authentication and private computations; be able to securely implement those techniques, as well as familiar with the process of building secure systems.

  10. Interdisciplinary aspects of privacy

Availability and prerequisites

This module delivery is available for selection on the below-listed programmes. The relevant programme structure will specify whether the module is core, optional, or elective.

In order to be eligible to select this module as optional or elective, where available, students must meet all prerequisite conditions to the satisfaction of the module leader. Places for students taking the module as optional or elective are limited and will be allocated according to the department’s module selection policy.

Programmes on which available:

  • MSc Information Security
  • MSc Information Security (Part time) (Year 1)
  • MSc Information Security (Part time) (Year 2)


To be eligible to select this module, students must have either taken in Term 1:


The course covers in depth major issues in computer security related to protecting privacy as well as threats to the privacy of computer users. In particular is covers the theory and practice of:

  • Private communications, anonymous communications, censorship circumvention and traffic analysis.
  • Private authentication, selective disclosure credentials for identify management, and zero-knowledge proof techniques.
  • Private statistics and computations through homomorphic encryption and secure multi-party computation and differential privacy.
  • Interdisciplinary (social, economic, legal, anthropologic) aspects of privacy

Students are introduced to both privacy threats such as pervasive surveillance, profiling, location analysis, and traffic analysis, as well as the technical mitigation techniques relying on modern cryptography and differential privacy.

An indicative reading list is available via


The module is delivered through a combination of lectures and supervised labs to support programming exercises. For the labs and programming exercises students, will be expected to run a pre-configured virtual machine using “VirtualBox” and be familiar with basic programming in C or Python.
