Identity Management (IDM) in cloud-based Internet-of-Things (IoT) applications is critical in many businesses. However, most conventional IDM systems are costly and hinder the innovation and greater customer experience. By using blockchain, a new way of managing the identities is proposed. This paper presents an initiative to improve IDM by integrating face recognition approach and blockchain technology in an integrated IoT -cloud application. To illustrate the proposed initiative, a decentralized campus wide printing service is chosen as a use case. In this use case, face recognition is used as an entry point to the service. Since face recognition involves a lot of complex computations and machine learning, this process is executed on a cloudlet, hence minimizing the need for massive data transfer to a distant cloud. Once a user's login information is digitally verified via immutable blockchain, smart contract is …
