A Web Based Crowdsourcing Framework: Lost Child Case

The great rise of smartphones has allowed the emergence of many new concepts such as the supply by the crowd. The constant movement of the crowd accompanied all the time by their mobile devices leads to the creation of needs and applications that require the joint contribution of the human effort and the use of new technologies. These information systems primarily help achieve tasks involving the collection of historical and real-time location data. In this paper, we introduce a framework which can be used by government organizations in order to encourage the public to participate in a crowdsourcing initiative while capitalizing on advantages of interactive technologies. We also present the overall design and implementation of this framework in the context of the child's loss.
