Problems solved by technology

First, it only considers the location privacy of workers, not the privacy of task locations
Second, it mainly performs task assignment based on the worker's traveling distance without taking into account other important factors such as the worker's traveling speed, which makes the assignment results sometimes unsatisfactory

Embodiment Construction

[0051] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0052] 1. System model and problem definition

[0053] figure 1 A system model for spatial crowdsourcing is described. For non-private space crowdsourcing (see figure 1 (a) There are three components, namely SC server (SC-server), workers (workers) holding mobile devices and space task requester (taskrequester). The SC server is responsible for assigning appropriate workers to space tasks created by task requesters. Workers need to report their private information (such as location and velocity) to the SC server through their mobile devices. Based on this framework, we give the following definitions.

Abstract

The invention discloses a task distribution system model of privacy protection space crowdsourcing. The task distribution system model comprises a space outsourcing server, an encryption service providing unit, a space task request unit and a worker mobile terminal; the space task request unit is used for creating the space task, and transmitting the task information to the space crowdsourcing server; the space outsourcing server is used for distributing the task to the worker mobile terminal; the encryption service providing unit is used for providing the privacy protection task distribution management for the space task request unit, the space crowdsourcing server and the worker mobile terminal. Furthermore, the invention further discloses a realization method of the system model. The system model firstly realizes the dual-party privacy protection in the space crowdsourcing, not only protects the privacy of the worker, but also protects the task privacy. The efficient task distribution is performed in the space crowdsourcing, and the privacy protection on two aspects of the worker and the task is provided.

Description

technical field [0001] The invention belongs to the field of computers, and specifically relates to a task distribution system model of space crowdsourcing, in particular to a task distribution system model of privacy protection space crowdsourcing; in addition, the present invention also relates to the task distribution system of privacy protection space crowdsourcing The implementation method of the model. Background technique [0002] Crowdsourcing has revolutionized the problem-solving landscape by outsourcing a task (usually performed by a designated agent) to the masses through an open call. Crowdsourcing can provide on-demand talent capacity and expert services at a much lower cost than hiring professionals, and has been successfully applied to transcribing books, protein folding, galaxy classification, and traffic monitoring. Recently, crowdsourcing has also been widely used in emergency management, as it enables efficient and low-cost collection of critical informa...
