Privacy Framework for Open Environments

With the explosion of internet services, new types of applications are emerged that are steered by self-interested entities. As there is no central control on these entities and they autonomously interact and deliver services to others, it creates an open environment that is the context of various types of nowadays applications. Formally, it can be described as Cooperative Distributed Systems in which interacting entities are autonomous and self-interested and they need capabilities of others to achieve their goals. Sensitive information is exchanged between entities while they are interacting. Exploiting sensitive information may violate entities´ privacy. This paper proposes a privacy model that captures privacy solutions at the interaction level. This work provides analysis of privacy issues in interactions of entities and provides solutions to reduce the risk of privacy violation in CDS. Accordingly, it results in a privacy framework that is associable in information systems and architectures. Integration of the proposed framework and scheduling solution as an example of information systems is presented in this paper as well. Also, the implementation details of applying privacy framework on architectural platforms are provided.
