We describe the application of our collaboration-oriented software engineering approach for the design of trust-aware systems. In this model-based technique, a specification does not describe a physical system component but the collaboration between various components which achieve system functions by cooperation. A system model is composed from these collaboration specifications and, by a set ...

Exchange of attribute credentials is a means to establish mutual trust between strangers that wish to share resources or conduct business transactions. Automated Trust Negotiation (ATN) is an approach to regulate the exchange of sensitive credentials by using access control policies. Existing ATN work makes unrealistic simplifying assumptions about credential-representation languages and creden...

We conduct an exploratory study using a customized Facebook application to understand how social ties are linked to economic measure of trust. We employ the Investment Game, a well-established economic game designed to generate a quantifiable trust measure. We consider the relationship between observed trust and three “revealed preference” tie strength measures: (1) the degree of interaction be...

Ours is, at its heart, a profession of service predicated on mutual trust. All too often policies aimed at resolving a particular problem in health care are inadequate not because they fail at what they were intended to do, but rather because of the unintended consequences, both direct and indirect, that are inevitable in complex systems where competing interests preclude unity of purpose. Ulti...

since last decades, there has been a growing interest in the human/social dimensions of natural resources governance especially the structure of social networks in achieving to successful co-management of natural resources. network analysis as a suitable tool in optimum planning of the “network management” of rangeland in regional scale, can improve inter-organizational decision-making and coor...

A trust negotiation is a mutual attribute-based authorization protocol between two entities. Trust Negotiation is an approach to regulate the exchange of sensitive information during this process. The proposed framework is a multisession dependable approach to trust negotiations. This framework supports voluntary and unpredicted interruptions, enabling the negotiating parties to complete the ne...

Ubiquitous computing has revolutionized interaction of humans and machines. Cloud computing has been mainly used for storing data and various computational purposes. It has changed the face of using the internet. But, as we know every technology has its pros and cons. Securing cloud environment is the most challenging issue for the researchers and developers. Main aspects which cloud security s...

Drawing principally on examples and literature from the Anglosphere, the author argues that the high salience given to "trust" and "trustworthiness" in recent scholarly literature, and which (notably in Putnam's work) attributes declining trust to a widely mistrusted mass media does not acknowledge the trustbuilding potential (realised in some instances) of interactive "Web 2.0" applications. D...
