Trust in ICT 1

Trusted data process and analysis

Information which is processed by home gateway and service platform should be trustworthy. Collected data
is processed and analysed in a gateway to decide extra actions depending on policies stored in the gateway.
Also, the gateway can put additional data (e.g. location, time, etc.) to collected data for sending data to
service platform. Service platform also can process and analyse data from the gateway to produce useful
information to a user. Since the gateway and service platform manipulate collected data, the trustworthiness
of information (i.e. processed and analysed data) is required to be maintained in each process.

Trustworthy application
Application (service provider) notifies processed information to user depending on their subscription profile.
The trustworthiness of application is recommended to be maintained in each process.

Privacy
When home energy management system notifies energy consumption information to user, providing
displayable consumed energy-related information to the end-user/consumer terminals (PC, mobile phone,
tablet, TV screen, etc.) may be unintentionally exposed. Application (or service provider) utilizes user’s data
for big data process, and this may cause user privacy issue.

5.2.5 Smart Office Service
5.2.5.1 Description

Trust based smart office service provides users with various office facilities based on the trust level of users.
This service can allow different type of permission (or access) to facilities according to user’s trust
information. For example, it is assumed there are three kinds of trust level like high, middle and low trusted
user. For the permission of cloud storage service, high trusted user can access with the authority of read,
write, and middle trusted user can access with the authority of read only. Low trusted user has no right to
access. Figure 9 shows an example of smart office service with different priority of users and different
permission to office facilities.
For the trust management, various properties like social/business relationship and membership can be
considered to analyse user’s trust level.
