Abstract:
Smartphones are more and more gaining
popularity, creating novel application areas as their
capabilities increase in terms of computational
power, sensors and communication. Emerging new
features of mobile applications and devices give
opportunity to new threats. As a result, research
addressing information access in smartphones
environment has proliferated. The important feature
of smartphones is to restrict the behavior of users
using applications and services to a certain level and
the existing access control mechanism on
smartphones mostly holds a coarse-grained.
This paper proposes how role-based access
control mechanism has motivated the creation of finegrained access control mechanism. In this paper, a
finer access control mechanism which is called
context-related role based access control (CtRBAC)
is presented. CtRBAC is based on traditional role
based access control by incorporating with the
contextual information of user and system
environment. CtRBAC categorizes the mobile phone
users according to their access rights of device’s
resources and services. By using simple policy and
context, the system fulfills necessity of existing access
control mechanism.
