Privacy-respecting Authentication – Ioannis Krontiris Speaker: Ioannis Krontiris, is a senior researcher in the group of Mobile Business
and Multilateral Security at Goethe University Frankfurt. Ioannis holds a PhD
from Mannheim University, Germany and a MSc degree from Carnegie Mel on
University, USA. He is currently involved in the coordination of the EU-Project
ABC4Trust (Attribute-based Credentials for Trust) where he is also leading the
architecture work package. His main research interests include Identity
Management, Online Privacy, Security and Privacy in Pervasive Environments.
Europe aims for an electronic identity management infrastructure as a basis for trustworthy
services in e-government and e-commerce to overcome fragmentation, closed solutions and lack of
user control and transparency. The outcome of the EU-project ABC4Trust wil result in important input
for the design of the upcoming electronic identity management infrastructure, by closing the gap
between the architectural framework level and the crypto level that slows down the adoption of privacy
respecting attribute-based credentials systems (Privacy-ABCs), as wel as making the infrastructure
independent of specific implementations.
Towards this goal, ABC4Trust is implementing and deploying privacy-ABCs in two actual
production pilots. These two user-trials wil give the opportunity for the first time to test credentials use
and performance on a large scale and provide experiences on their operation, interoperability and user
acceptance. The first pilot scenario wil be deployed at a school in Soederhamn, Sweden, where
young students (youngsters and teenagers of both sexes) wil be able to communicate in an
anonymous and privacy preserving way with other pupils and with school health personnel (doctors,
nurses, psychologists and other coaches). The second pilot scenario wil be deployed at the University
of Patras, Greece, where students wil be able to anonymously evaluate courses they attended.
Thus, ABC4Trust is building its architecture based on privacy requirements collected within the
European setting (e.g. Greece and Sweden). However, privacy concerns differ in the international
setting. These differences can be attributed to differences in cultural values and perception of privacy,
differences in the familiarity with Web privacy practices, or even differences in regulations. In that
respect, international cooperation could greatly help exchanging views with other cultures, col ect
different application scenarios and requirements from other cultures and effectively broadening the
perspective of privacy-ABC architecture.
It is, therefore, an open research question to be discussed how privacy relevant processing with
and in countries like Brazil, India or South Africa can be handled within ABC-scenarios. How are
concepts like proportionality, unlinkability, minimal disclosure etc. being perceived in such countries?
How other legal systems outside Europe can be affected by and have effects on Privacy-ABCs?
Technological research can also be greatly benefited from international cooperation when it
comes to taking under consideration the human factor in designing technologies. How people perceive
technological solutions and how that affects the adoptability of the corresponding technologies? How
to best explain to people the potentials and features of the existing solutions? How to best design
user-interfaces to encourage usability and adoptability? The answers to these questions wil vary for
different cultures and by opening up beyond the European borders wil give us a great insight in these
aspects and eventual y help us design better technology.
To address the above challenges, col aboration opportunities should allow EU-project consortia
to open up and include various kinds of actors in the international setting: user communities,
governmental organizations, regulatory authorities, and research institutes. A framework for enabling
such col aboration should encourage joint working groups, organization of public events with experts
from both sides and collaboration in standardization activities.
Soma: origins and paths of an anarchist experiment Levier has been hosting 'Soma: body collaboration workshops' since 2007. Created in Brazil as an anarchist therapy, by Roberto Freire, Soma is used at these intensive workshops as a social laboratory, bringing art, activism and learning new skills together. Participants are invited to play as a way to rediscover the body, sharing collaboration g
Limoxifen: Developing a new drug as a supplement for hormonal treatment of breast cancer Background According to the guidelines of treating hormone-sensitive breast cancer, hormonal therapy is prescribed for 5 years to women who have already received other treatments. This improves their prognosis. However, hormonal therapy can produce numerous side effects, such as reduced sexual desire, joint pa
