Privacy Considerations when Designing Social Network Systems to Support Successful Ageing
summary
A privacy-by-design prototype envisions a smartphone-linked social recommender that logs activity, location and facial cues to suggest local events, but user testing finds sharp limits: 6-person sociograms show many will share location broadly while tightly guarding mood and sensitive details from friends, and a follow-up 20-person Johari-window study reveals people often want privacy from their own data (not knowing declining steps or cognition). Participants reject automatic mood-publication, prefer fine-grained friend-based controls or overlapping groups, and want shorter time windows to avoid discouraging users.
