Logging you, Logging me: A Replicable Study of Privacy and Sharing Behaviour in Groups ofVisual Lifeloggers. Proc. ACM Interact. Mob.

Low cost digital cameras in smartphones and wearable devices make it easy for people to automatically capture and shareimages as a visual lifelog. Having been inspired by a US campus based study that explored individual privacy behaviours ofvisual lifeloggers, we conducted a similar study on a UK campus, however we also focussed on the privacy behaviours ofgroups of lifeloggers. We argue for the importance of replicability and therefore we built a publicly available toolkit, whichincludes camera design, study guidelines and source code. Our results show some similar sharing behaviour to the US basedstudy: people tried to preserve the privacy of strangers, but we found fewer bystander reactions despite using a more obviouscamera. In contrast, we did not nd a reluctance to share images of screens but we did nd that images of vices were sharedless. Regarding privacy behaviours in groups of lifeloggers, we found that people were more willing to share images of peoplethey were interacting with than of strangers, that lifelogging in groups could change what denes a private space, and thatlifelogging groups establish dierent rules to manage privacy for those inside and outside the group.
Designing the Wearable Camera
This camera was designed to study privacy and sharing behaviour in groups of visual life-loggers. Files are present at: https://github.com/vllstudy16/vllstudy16
