for an Individual?
▪ Assets need to be collected by the Individual
▪ Data need to be stored at the side of the
individual
▪ The individual should choose:
▪ When to share
▪ What to share (data/analytics/….)
▪ How to share (anonymous/encrypted/etc….)
▪ With whom to share
▪ Under which conditions to share
▪ The Individual should be aware of his risk

▪ The Individual should trust the platform and be
trusted by the platform!
