Towards a unified trust framework for trust establishment and trust based service selection

Trust is an important factor in online communication. Trust is used as a criteria for service selection. The first step to build a trust solution is to define trust and trust principles. Most current trust-based service selection approaches do not define trust and they establish trust for services by ranking services or finding the services´ compliance and reputation. In addition, most studies do not consider trust principles that underpin trust concepts and do not address trust challenges that should be resolved as a part of the trust solution. This paper proposes a framework to build trust for services and to select services based on trust criteria. The main purpose is to move towards a unified framework that includes the main trust components to have a complete trust solution based on trust definition and trust principles.
