Individuals in the Information Society want to protect their autonomy and retain control over personal information, irrespective of their activities. Information technologies hardly consider these requirements, thereby putting the privacy of the citizen at risk. Today, the increasingly collaborative character of the Internet enables anyone to compose services and to contribute and distribute information. Furtehrmore, individuals will contribute throughout their life leaving a life-long trail of personal data.

This raises substantial new privacy challenges: a first technical challenge is how to protect privacy in emerging Internet applications such as collaborative scenarios and virtual communities. A second challenge is how to maintain life-long privacy.

PrimeLife will resolve the core privacy and trust issues pertaining to these challenges. Its long-term vision is to counter the trend to life-long personal data trails data without compromising on functionality. We will build upon and expand the sound foundation of the FP6 project PRIME that has shown how privacy technologies can enable citizens to execute their legal rights to control personal information in on-line transactions.

Resolving these issues requires substantial progress in many underlying technologies. PrimeLife will substantially advance the state of the art in the areas of human computer interfaces, configurable policy languages, web service federations, infrastructures and privacy-enhancing cryptography.

Our team at SAP research France is mainly involved in three activities:

  • Anonymity: in which we are currently working on a privacy risk estimation system able to evaluate the strength of a privacy policy according to the dataset on which it is applicable. This system is providing a risk metric indicator and can propose anonymization solutions that could be applied to the dataset and to the policy in order to minimize the private data inference risks.
  • Privacy policy: in this project we are leading the design and implementation work package. Our role is to develop a new advanced privacy policy language supporting access control, data handling, trust and obligation management.
  • Policy composition: the main goal of the PrimeLife project is to bring privacy to the real life application, and particularly web 2.0 applications. One of the particularities of this technology, is the possibility to combine more than one services in order to perform a task. This feature is called service composition (mash up, distributed workflows etc…). This concept raises new challenges regarding to the private data protection, since most of these services are dealing with different privacy policies. We are working on a smart system able to compose these policies in a non conflicting way in order to provide stable security system.

In this project we are collaborating with the most distiguished industrial partners like Microsoft (EMIC), IBM Zurich.
