Abstract
The privacy and security concerns in a crowdsourcing information system are dependent on how the ownerships of the content created by the system are managed. A crowdsourcing information system can use different ownership models: (a) creator owned, (b) system owned, and (c) group owned. In creator- owned systems, the creator of a data object is responsible for setting the access control constraints for the data object she creates. Examples of crowdsourcing information systems that use this model are online social networks and blogs. In system-owned crowdsourcing systems, individual contributors do not have the privilege of setting the access control policies for the content they create as part of their activities.
