The success of the Web is based largely on its open, decentralized nature; at the same time, that allows for a wide range of perspectives and intentions. Trust is required to foster successful interactions and to filter the abundance of information. In this review, we present a comprehensive survey of trust on the Web in all its contexts. Three main targets of trust are identified: content, services, and people. Trust in the content on the Web, including webpages, websites, and Semantic Web data is addressed first. Then, we move on to look at services including peer-to-peer environments and Web services. This includes a discussion of Web policy frameworks for access control. People are the final group, where we look at the role of trust in web-based social networks and algorithms for inferring trust relationships. Finally, we review applications that rely on trust and address how they utilize trust to improve functionality and interface.
