Abstract: A submission auditing system is described herein that audits to measure participation and to prevent fraud in online crowd-sourced competitions. Auditability increases the acceptance of crowd efforts. Individual contributors and competition organizers also want to have the individual contributors receive credit from the project sponsor(s), their employer, and/or government or other entities for their time investment. An employer may encourage employees to volunteer time with various charitable organizations, and may use the system to monitor participation and award prizes based on participation. The submission auditing system addresses the problem of auditing engagement in crowd-sourced scenarios, by providing a workflow for measuring engagement with a crowdsourcing project, detecting fraud as part of that measurement, and then delivering a receipt for the individual and third parties that provides tracking for participation.
