AI Technical Summary

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 privacy-protected space crowdsourcing task assignment system model, which includes a space crowdsourcing server, an encryption service providing unit, a space task request unit, and a worker mobile terminal; the space task request unit is used to create a space task, and The task information is sent to the space crowdsourcing server; the space crowdsourcing server assigns tasks to the workers' mobile terminals; Workers' mobile terminals provide privacy protection task assignment management. In addition, the invention also discloses the realization method of the system model. The present invention realizes privacy protection of both parties in space crowdsourcing for the first time, not only protects the privacy of workers, but also protects the privacy of tasks, realizes efficient task allocation in space crowdsourcing, and provides privacy protection for both workers and tasks.

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...
