3 Trust in ICT

– Customer & Market: Satisfaction, Life cycle of service, Developer ecosystem, etc.;

– Business model process (infrastructure): Mobile, Social, Cloud, Data analytics, Interoperability,
Standardization, etc.

With these backgrounds, this clause intends to categorize new market disruption into three platform types
of products, market and software. In fact, on the road of disruptive innovation, the related researches are
almost about the platform strategies and the meaning of platform business has been expanded from the
products & services to market & software ecosystem. In these three types of platforms, there are rationalities
specific for each platform as follows [b-Sandberg] and the rationalities are related to the trust attributes [b-
Mayer, b-McKnight]:
– Rationality of product platform (Integrity, ability and functionality): Modularity allows re-use and
decreases complexity, standardization of platform combined with customization allows economies
of scale and scope. The overarching goal is product efficiency and functionality;
– Rationality of market platform (Integrity, ability and benevolence): Re-use of infrastructure allows
efficient transactions. Focus on market efficiency and transaction costs. Competitive advantages are
achieved by attracting a large number of providers and customers through strategic decisions;
– Rationality of software ecosystem platform (Integrity, reliability and helpfulness): Shared
functionality in codebase allows specialization, distribution of development costs and access to
users. Commonality achieved through shared platform rather than application area.
Based on disruptive model theory and ICT symmetry following Table 9-1 is presented, and detailed examples
are shown in Appendix III.

10 Use cases of Trust Provisioning for ICT infrastructures and services
This clause discusses six use cases of trust provisioning for ICT infrastructures and services. The use cases can
be shown in wide range of service domains requiring trust. Although each use case has different purposes
and consists of different actors, it is true that trust can play an important role of mitigating risks of violation
of security as well as privacy and mediating interactions among actors.

Use case #1: Trustworthy smart home service

Trustworthy smart home service is a service to monitor, control and manage home appliances and smart
devices by using trust information. This use case focuses on a trust provisioning at home. The home gateway
collects personal data from the household devices. After aggregating the personal data, the home gateway
sends data to the remote service platform and service platform generates trust information from data and
provides trust information to service providers for managing home appliances and other devices.

Use case #2: Trustworthy smart office service
This use case allows users utilizing various facilities in office based on the trust level of users. For the trust
management, various properties like social/business relationship and membership of each user can be
considered to determine each user’s trust level. Smart office provider offers office facilities to users based
on the users’ trust level estimated by trust management platform.
