Abstract

Today, most of the services one may think of are based on a collaborative paradigm (e.g., social media services, IoT-based services, etc.). One of the most relevant representative of such class of services are inter-organizational processes, where an organized group of joined activities is carried out by two or more organizations to achieve a common business goal. Inter-organizational processes are therefore vital to achieve business partnerships among different organizations. However, they may also pose serious security and privacy threats to the data each organization exposes during the collaboration. This is mainly due to the weak trust relationships that may hold among the collaborating parties, which result in a potential lack of trust on how data/operations are managed. A promising approach to cope with this issue is leveraging on blockchain technology by encoding with smart contracts the business process execution. This brings the benefits of trust decentralization, transparency, and accountability of the service composition process. In this thesis, we propose a framework to deal with the challenges in executing a inter-organizational business processes on the blockchain. In particular, we focus on how blockchain can be exploited to ensure a correct and secure execution of a business process collaboration, a dynamic discovery and assignment of services to process, a secure off-chain resource sharing, and a trustworthy certification process. Finally, we show the results of our proposal and outline possible future research directions.
