This document summarizes a presentation given by Souheil Bcheri of Eurodocs AB about a pilot project testing the company's Privacy-ABC technology. The project involved 381 students, parents, and teachers from a school in Söderhamn, Sweden. The technology allowed users to authenticate to a restricted area application with credentials that protected their anonymity and privacy. Over two rounds, the pilot demonstrated how the technology could enable anonymous chat, discussions, counseling, and document sharing while verifying users' school affiliation. Feedback showed users understood the privacy concepts and trusted the system to protect their privacy. Next steps may include expanding the technology's use to other schools and organizations.

Objectives of the Pilot
• To demonstrate how ABC technology can
successfully provide trusted identification
while protecting anonymity and privacy of
children in real life applications where this is
desirable
• To meet the requirements of the school and
local (in this case Swedish) authorities.
 The Swedish National Agency for Education
 The Swedish Data Inspection Board

The Swedish pilot scenarios
• School internal community interaction among students,
guardians and school personnel
• Main scenarios:
 Chat communication
 Political discussions
 Counseling with health personnel
 Document sharing and access

Political Discussions
• For some people the ability to express a
political opinion anonymously is essential to
discuss sensitive subjects.
• Students prove that they belong
to the school but can still
remain anonymous

nationalities

10. 20.01.2015 Souheil Bcheri, Eurodocs AB
Counseling
• Get help and advice from school personnel
 Students will discuss, get help or get advice from
authorized professionals regarding
psychological, physical and other problems
 The students prove to
belong to the school
but can still remain
anonymous

11. 20.01.2015 Souheil Bcheri, Eurodocs AB
Sharing Documents
• The school is producing many important
documents (exam results, grades, individual
development plans, etc.) that need to be
shared with and distributed to the students
and their parents.

Necessary features
• The school needed a way to stop usage of already
issued credentials in case a student
 changes class or subject
 no longer belongs to the school
 …
• The school is responsible for the well being of the
students while at the school and using tools
provided by the school
 What if anonymous users misbehave?

Approach
• Users were identified by smart cards they
received from the school administration. The
smart cards contained ABC software, credentials
and attributes (name, class, date of birth,
gender, etc.)
• Students, guardians and school personnel used
their smart cards to sign in to the school
application (the Restricted Area Application)
