Experience Design Framework for Securing Large Scale Information and Communication Systems
1. Security and Privacy Concerns
2. Information and Communication Systems (ICSs) Concerns
3. Complex Systems and ICSs
4. Security and Privacy Framework
5. Implications
6. Conclusions

1 . Security and Privacy Concerns
As designers, what and howdo we think about
security and privacyof Information and
Communication Systems?
People have di!ferent privacy and security concerns

responsibility on the users’ hands
between public and private
Unknown and unpredictable security and privacy threats and failures
2. ICSs concerns
Heterogeneity of users

diverse people: a “world” using icss
ICSs entailmultiple use scenarios
same system, different use
different security and privacy scenarios
Use scenarios change over time
Information and Communication Systems also change
3. Complex Systems and ICSs

As complex systems, ICSs entail user-system coevolution

ICSs entail a challenge forboth design practice
and design pedagogy
6. Conclusions
We proposed an experience design framework constituted
by six security and privacy principles

Our attempt is to open a conversation about security
and privacy, and also about the implications of user-system
coevolution in ICSs for experience design.
