Digital identities represent who we are when engaging in
online activities and transactions. The rapid growth in the
number of online services leads to in an increasing number
of different identities that each user needs to manage.
As a result, many people feel overloaded with identities
and suffer from password fatigue. This is a serious problem
and makes people unable properly control and protect
their digital identities against identity theft. This paper
discusses the usability and privacy in online identity
management solutions, and proposed a general approach
for making users better able to control and manage their
digital identities, as well as for creating more secure identity
management solutions. More specically, we propose
a user-centric approach based on hardware and software
technology on the user-side with the aim of assisting users
when accessing online services.
