Report UN Rapporteur for Privacy

what is privacy Posted on Mon, May 16, 2016 19:01

This is the first
report of the first United Nations Special Rapporteur for Privacy. He is
planning to look for a definition of privacy in order to make the understanding
of the right more relevant to a digital age where the internet operates without
borders. The rapporteur is pursuing an analysis of privacy as an essential
right which enables the achievement of an over-arching fundamental right to the
free, unhindered development of one’s personality. Not everyone will find a
definition a good idea, but it is at least a very interesting exercise. The
report also mentiones some important evolutions and cases.

On the site of the
International Justice Resource Center
you can find a good summary of the report.

Attribute Based Credentials ABC4Trust

pseudonymisation Posted on Sun, May 01, 2016 11:42

“The goal of ABC4Trust
is to address the federation and interchangeability of technologies that
support trustworthy yet privacy-preserving Attribute-based Credentials (ABC).
So far credentials such as digitally signed pieces of personal information or
other information used to authenticate or identify a user where not designed to
respect the users privacy. They invariably reveal the identity of the holder
even though the application at hand often needs much less information, for
instance only confirmation that the holder is a teenager or is eligible for
social benefits. In contrast to that, Attribute-based Credentials allow a
holder to reveal just the minimal information required by the application,
without giving away full identity information
. These credentials thus
facilitate the implementation of a trustworthy and at the same time
privacy-protecting digital society.”

“1st Pilot – Privacy
in Online Evaluation and Feedback Systems

Deployment: Patras University, Greece
Scenario: Students evaluate anonymously the courses
they attended

2nd Pilot – Privacy
in social communication fora

Deployment: Söderhamn Secondary School, Sweden
Scenario: Pupils communicate using pseudonyms on
the school communication system

Benefits of

– Privacy-ABCs are by default untraceable (no
– Enable minimal disclosure (user reveals only the
necessary information)
– User can chose to stay anonymous or generate
(unlimited number of) pseudonyms
– Advanced security (no sharing of credentials,
device-binding for extra protection)

implementation with ABC functionality

– Coded in the ABC-Engine
– Exposed to the application layer as web-services
– As open source.

For developers

– Easier application development
– Cryptographic operations are abstracted away from.

For users

– Only need to install a browser plug-in”

Handbook On Increasing Resilience in a Surveillance Society

surveillance Posted on Sat, April 23, 2016 15:18

Key considerations for policy-makers, regulators, consultancies,
service providers, the media, civil society organisations and the public

Beknopte en
overzichtelijke gids naar een bewuster omgaan met toezichtsystemen, zowel
die van bedrijven als die van de
overheid. Met vragen die de belangrijkste betrokken partijen (waaronder ook
consultants en IT-dienstenleveranciers) zich zouden moeten stellen. Bevat ook
achtergrond met definities en een overzicht van maatregelen voor alle
betrokkenen. Zeer goede basistekst.

aim of the IRISS handbook on Increasing Resilience in Surveillance Societies is
to help increase resilience in surveillance societies. It is aimed at six main
groups of stakeholders: policy-makers and regulators, consultancies, service
providers, the media, civil society organisations and the public.”

handbook is divided into three main parts.

One provides some background on resilience in surveillance societies.
defines the terms and identifies features of resilience and today’s
surveillance society.

Two lays out
a set of questions addressed to each of the stakeholder groups.
The questions are intended to provoke consideration of a proposed or existing
surveillance system, technology, practice or other initiative, whether the
surveillance system is truly necessary or proportionate, whether stakeholders
are being consulted.

Three offers a list of measures
that can be taken to increase resilience in a
surveillance society and to restrict the scope of surveillance systems to what
can be legitimately justified and to minimise the impacts of surveillance
systems on the individual, groups and society.”

handbook is not intended to be or replace a full-fledged surveillance impact
assessment (SIA) or privacy impact assessment (PIA). However, the handbook may
stimulate awareness that an SIA and/or PIA should be undertaken, especially in
the context of a mass surveillance system.”

Increasing Resilience in Surveillance Societies (IRISS) project received
funding from the European Union’s Seventh Framework Programme for research,
technological development and demonstration under Grant Agreement No. 285593.
IRISS comprises 16 partners from nine EU countries.”
