Abstract

The invention discloses a task assignment method for privacy protection in space crowdsourcing, involving three entities, including space crowdsourcing platform, agents and workers, using an anonymous data collection protocol to safely send user data to space crowdsourcing Platform; use the reverse auction-based task allocation algorithm to help the spatial crowdsourcing platform generate task allocation and reward reward schemes, and ensure the honesty of users. Through the above method, the privacy-protected task allocation method in space crowdsourcing provided by the present invention uses an anonymous data collection protocol to ensure the security of worker location data, and uses a reverse auction-based task allocation algorithm to ensure the honesty of workers , is based on a semi-trusted model, has the advantages of high security and high efficiency, and has an extremely bright application prospect in the field of spatial crowdsourcing.

Description

technical field [0001] The invention relates to the fields of spatial crowdsourcing, spatiotemporal data processing and mobile computing, and in particular to a task assignment method for privacy protection in spatial crowdsourcing. Background technique [0002] In recent years, a new mode of solving work problems that are difficult for computers to complete alone by integrating the labor force of the network platform - Crowdsourcing (Crowdsourcing) has received extensive attention from industry and academia. The so-called crowdsourcing usually refers to "a distributed problem-solving model that outsources the work tasks performed by full-time employees in the past to non-specific solution provider groups in a voluntary form through an open Web platform." As the embodiment of "group wisdom", crowdsourcing has a wide range of application scenarios and markets. For example, early crowdsourcing platforms usually refer to "question answering system" platforms, such as Wikipedia...
