hen surfing <strong>the</strong> web today,<br />

users leave digital traces<br />

without noticing. This trail <strong>of</strong><br />

personal data puts <strong>the</strong> autonomy <strong>of</strong> <strong>the</strong><br />

individual at risk in an unprecedented<br />

way. Unlike footprints on <strong>the</strong> beach,<br />

which are washed away by <strong>the</strong> sea, data<br />

stored online do not dissolve after time<br />

but remain available <strong>for</strong> a lifespan <strong>and</strong><br />

even beyond. But personal in<strong>for</strong>mation<br />

must only be carved in stone where <strong>the</strong><br />

user is aware <strong>of</strong> this an explicitly decides<br />

to do so.<br />

Approach<br />

Preserving privacy over a whole lifetime, in<br />

collaborative settings <strong>and</strong> virtual communities<br />

imposes new challenges to research. The<br />

paradigm <strong>of</strong> privacy protection by data<br />

minimisation fails <strong>for</strong> use cases such as web<br />

2.0 applications where users need or want to<br />

reveal large amounts <strong>of</strong> personal data. Here<br />

<strong>the</strong> EC-funded project PrimeLife aims to<br />

solve <strong>the</strong> challenges concerning privacy, identity<br />

<strong>and</strong> trust management. PrimeLife’s vision<br />

is to counter lifelong data trails without compromising<br />

on functionality. This requires<br />

substantial progress in <strong>the</strong> underlying technologies,<br />

<strong>and</strong> subsequent adoption. To reach<br />

<strong>the</strong>se aims PrimeLife is segmented into<br />

highly interacting activities.<br />

Privacy in Life<br />

The project is arranged around <strong>the</strong> activity<br />

“Privacy in Life” which studies how privacy<br />

can be established in real life. Demonstrators<br />

will be built to validate <strong>the</strong> research done <strong>and</strong><br />

to show how <strong>the</strong> challenges <strong>of</strong> lifelong privacy<br />

can be met. The demonstrators build upon<br />

<strong>the</strong> requirements collected <strong>and</strong> <strong>the</strong> research<br />

done within PrimeLife’s o<strong>the</strong>r activities.<br />

Mechanisms<br />

The activity “Mechanisms” researches on<br />

basic methods <strong>for</strong> privacy-enhancing identity<br />

management <strong>and</strong> trust establishment inter<br />

alia by refining existing cryptographic methods<br />

such as anonymous credentials.<br />

Privacy <strong>and</strong> Identity Management<br />

in Europe <strong>for</strong> Life<br />

Privacy Live<br />

The dissemination activity “Privacy Live”<br />

interacts with <strong>the</strong> community <strong>and</strong> o<strong>the</strong>r EU<br />

projects to support <strong>the</strong> use <strong>of</strong> <strong>the</strong> developed<br />

privacy-enhancing mechanisms. To this end,<br />

PrimeLife organises workshops, contributes<br />

to st<strong>and</strong>ardisation bodies <strong>and</strong> provides educational<br />

material <strong>for</strong> pupils, students <strong>and</strong> <strong>the</strong><br />

broader public.<br />

Usability<br />

The best privacy, identity <strong>and</strong> trust management<br />

mechanisms are useless if intuitive interfaces<br />

are missing. Users need guidance to<br />

underst<strong>and</strong> privacy-enhancing identity management,<br />

trust <strong>and</strong> assurance models or privacy<br />

policies. Such interfaces are provided by<br />

<strong>the</strong> activity “Usability”.<br />

Policies<br />

“Policies” are <strong>the</strong> central mechanism <strong>for</strong> enabling<br />

privacy, identity <strong>and</strong> trust management.<br />

In particular, policies must govern such a<br />

system from end-to-end <strong>and</strong> throughout different<br />

applications. All o<strong>the</strong>r activities will<br />

employ policies <strong>for</strong> practical implementations<br />

in tools or demonstrators. The goal <strong>of</strong> <strong>the</strong><br />

policy activity is to ga<strong>the</strong>r <strong>the</strong> requirements<br />

<strong>and</strong> to specify <strong>the</strong> required languages.<br />

Infrastructures<br />

The activity “Infrastructures” addresses <strong>the</strong><br />

question what kinds <strong>of</strong> infrastructures are<br />

needed <strong>for</strong> privacy, identity <strong>and</strong> trust management.<br />

It collects <strong>the</strong> requirements <strong>of</strong> such<br />

an infrastructure <strong>and</strong> proposes how <strong>the</strong>se can<br />

be met.<br />
