About the Report:

The outsourcing computations in distributed environments suffer from the trust problems between the outsourcer and the workers. The rational lazy-and-partially-dishonest workers in the outsourcing computation model seems sufficient, but it still does not represent the real life situation. The notion of outsourcing computation is closely related to crowdsourcing. Crowdsourcing is an emerging and exciting technology to acquire services by soliciting contributions from a large group of community, rather than traditional employees or suppliers. With crowdsourcing, the power of people (and hence, the "crowd") will be unleashed to help solving our problem. The situation becomes complex in a commercial setting. Participants will receive payment upon their contribution, and hence, there is incentive for dishonest participants to claim credit for work they did not perform. Additionally, the job owner may not honour its obligation to pay upon the completion of participants' contribution. In this talk, we will go through the challenges that are related to the fairness for all entities, and some research questions.
