Another important set of issues concerns privacy and selfidentity.
Through their mobile devices, people will not only
be always in touch with one another but may be willing
to share their mobile digital traces: the locations they
pass through, their activities, the profiles of other people
they pass on the way and the content they consume and
produce. This also suggests that increasingly people will
have to worry about personal information getting into the
wrong hands. It also raises issues about how we protect the
more vulnerable in our society, such as children.
