A resilient and secure two-stage ITA and blockchain mechanism in mobile crowd sourcing

Mobile crowd sourcing offers a way for an organization to gain afar their "base of minds" of workforce offers in the form of idea competitions or innovation contests where task is divided among individuals to achieve a pooled result using mobile devices. However, mobile crowd sourcing consequence to an urban bias in addition to other key challenging issues such as safety, privacy and connectivity or data fault tolerance. Fault tolerance in mobile crowd sourcing is a property to tolerate any fault related to data collected or the working of the system. Further, it is needed to ensure a secure resilient mechanism due to de-centralized behavior of the network. In this paper, we have proposed a resilient-improved two-stage auction (ITA) and blockchain mechanism in mobile crowd sourcing beneficial for the organizations. The resilient technique and secure scheme is beneficial for the organizations that select the workers according to their budget and time. Further, an akka API tool is implemented upon already existing mobile crowd sourcing technique i.e. ITA. The proposed resilient mechanism is initially implemented over. The proposed resilient ITA mechanism is analyzed over further crowd sourcing mechanisms needed for workers selection in order to benefit the organizations. Further, the resilient-ITA is measured against database connection loss that is considered as a promising type of fault occurring during the workers selection.
