Project summary

The overall goal is to enable communicating organisations to include privacy enhancing technologies (PETs) in large-scale web-based services for the general public and customers.

Motivation for this project arises from the following:

1. Communication services and networks have become complex and highly interconnected, and the cost of storage is approaching zero for all practical purposes. This means that there is no longer any pressing need to remove redundant or duplicate data with the result that the volume of stored data is enormous and constantly increasing. The web makes it easy to access data and easy to aggregate and correlate data from numerous different sources.

2. In the long run, access restriction alone cannot suffice to protect privacy and the enforcement of privacy using traditional methods of access control/PETs becomes difficult since it does not scale adequately to the increased volume of data/information.

3. Therefore it is necessary to investigate new approaches to privacy enhancing technologies in order to arrive at technologies that are scalable, practical and in accordance with relevant legislation.

Principal objectives and subgoals

The primary objective is to devise a framework for facilitating the development of the next generation of privacy enhancing technologies in large-scale web-based services.

The sub-objectives are as follows:

1. Analyse the requirements communicating organizations have when using next-generation PETs in large-scale web-based services

2. Analyse and identify gaps and hindrances to the application of PETs in such services

3. Devise a framework to assist in the development of web-based services when these services include next-generation PETs

4. Perform a case study and validation of the results using the MinSide service

5. Disseminate knowledge and results from the PETweb project
