Prototype

This page contains an overview of the prototypes and open source results produced within PrimeLife.The site will be updated in regular intervals until the end of the project in 2011.

Identity Mixer

Identity Mixer (idemix) is an implementation of the Camenisch-Lysyanskaya anonymous credential system based on the Strong RSA assumption. The implementation is in Java and provides as a library the necessary cryptographic functions to issue and use credentials. It does however not provide any credential selection UI or policy components.

PRIME Core

The PRIME core is a toolbox to enhance applications with privacy features. It provides functionality via web services, so it can be used platform independent.

MediaWiki - Privacy enhanced access control extension

MediaWiki is enhanced with the PRIME-based access control based on policies and credentials. This way, MediaWiki users are enabled to restrict the access to a wiki page owned by the user to users proving the possession of indicated properties certified by (an) indicated party/ies. That way, the users are not obliged to rely on user accounts (provided by MediaWiki) when restricting access. This approach opens up potentials to foster social contacts without requesting any kind of managing identity data with the application platform. So, it allows to decouple functionality of identity management from actual application functions.

MediaWiki - Reputation extension

MediaWiki is enhanced by functionality to rate page revisions as well as to display the average rating of a page revision, to display the rating history, and to update the reputation of the author of the revision using the ratings weighted by raters' reputation. It uses policies and credentials and requires the MediaWiki - Privacy enhanced access control extension.

phpBB - Privacy-enhanced Access Control

Forum platform phpBB is enhanced with the PRIME-based access control based on policies and credentials. This way, phpBB users are enabled to restrict the access to an element of the content structure owned by the user (which could be the forum itself, topics, threads, and individual posting) to users proving the possession of indicated properties certified by (an) indicated party/ies. That way, the users are not obliged to rely on user accounts (provided by phpBB) when restricting access. This approach opens up potentials to foster social contacts without requesting any kind of managing identity data with the application platform. So, it allows to decouple functionality of identity management from actual application functions.

phpBB - Privacy-Awareness Mod

The perception of privacy in social settings depends on the anonymity or identifiability of the users on the one hand, and on the available audience, i.e., who may note the disclosed personal data, on the other hand. The privacy-awareness mod helps users to assess their level of privacy while interacting with others on the Internet and enable them to make informed decisions whether to disclose personal data in a phpBB forum.

First Version of Tools on Data Protection Mechanisms

This tool implements the greedy algorithm designed by UNIBG and UNIMI to solve the problem of creating unlinkable fragments in the storage of sensitive attributes.

First Version of Tools on Access Control Mechanisms

This prototype is a client-server web application, designed by UNIMI and UNIBG, that provides data sharing capabilities in an outsourcing scenario where the storage service provider is trusted neither for data confidentiality nor for enforcing access control functionalities.

dudle - Privacy-respecting establishment of collaborative groups

Dudle is an opensource implementation of doodle. Additionally it offers privacy-enhanced features which are achieved using homomorphic encryption.

Clique - privacy enhanced Social Network Site

Clique is a privacy enhanced Social Network Site based on the Elgg Open Source Social Network Site software. Clique is designed and implemented by TILT. It provides features for implementing and visualising audience segregation by means of fine grained access control policies. The prototype can be accessed clique.primelife.eu here.

Scramble - Enforce selective access control to Social network sites

Scramble! provides a mechanisms for users to enforce access control over their one data. Its main target is to protect users to share sensitive information with Social Network Sites providers. Allows the creation of a web of friends and by means of encryption to enforce access rights. Scramble allows users to create groups of friends and transparent decryption.
