Trust in ICT 1

In case trust evidence is not available in one administrative domain, architecture must support the
propagation of recommendations requests to other domains, for example, using existing social network
connections such as buddy lists.
As future work it is needed to use context information to improve the recommendation process. For example,
context can be used to determine the suitable target entities to request recommendations from. This will
allow anonymous and still useful recommendations exchange. Context can also be used to dynamically adapt
the user goals. In certain context situations (e.g. health care service) users may not have privacy as first goal
when they need the best service adaptation (e.g. to send an ambulance to their current trustworthy location).

7 Architecture framework for trusted social cyber physical infrastructure

7.1 Social-Cyber-Physical Infrastructure

While traditional ICT infrastructures have focused on computer-centric approaches to data processing as well
as network-centric approaches to information collection, the emerging ICT infrastructures will use human-
centric approaches. The transformation toward a hyper-connected society will contribute to our everyday
lives with ICT problem-solving support, and will (hopefully) change to a more user-friendly, fun and enjoyable
experience in terms of ICT provision.

The advent of applications such as content distribution, cloud computing and IoT requires the underlying
network to be able to understand the context of various services. An emerging networking paradigm enables
in-network knowledge generation and distribution in order to develop the necessary network control
intelligence for handling complexity and uncertainty of future networked services and the multitude of users
[43]. To support this paradigm, telecommunication infrastructures must be enhanced to make better use of
the knowledge of networks, services, end users and their devices.

The evolving trend of telecommunication systems and ICTs has been to move from the living space of home
appliances to large-scale communities in buildings, such as workspaces and digital infrastructures like smart
cities. The IoT plays a major role in the rapid development of these technologies. The IoT initially focused on
network connectivity for supporting heterogeneous communications interfaces but recently it has been
developing to provide convergent services that integrate ICT in various industrial areas to offer a common
service platform. These convergent services have been required to obtain reliable knowledge from raw data.
As an aim of intelligent service provision is to make autonomous decisions without human intervention, trust
has been highlighted as a key issue in the processing and handling of data, as well as the provisioning of
services which comply with users’ needs and rights.
