Embodiment Construction

[0035] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0036] The structure diagram of the TOR method is as follows figure 1 shown.

[0037] When a car-hailing user as a requester sends location information in order to obtain a taxi service, the LBS (Location Based Service) server can broadcast the verification requirements to the neighboring car-hailing users. These users are called observers, and the observers are required to check. Whether the distance between the requester and the observer is within the radius r of the requester; in order to ensure the credibility of the verification and improve the verification efficiency, the trust evaluation based on the requester and the observer is used to support the trust judgment. Only when the value is greater than the threshold will the trusted observation process within the radius r be invoked.

Abstract

A false location recognition method applied to a car-hailing system, comprising the following steps: Step1, U i Send query message to LBS server Q [ i ]=(U i ,l i ,sv i ,st i ); Step2, the LBS server sends U i Respond to query results QH [ lbs ]=( lbs,j i ,r,st i ),if RT i < δ or ST i < δ , j i = 0, LBS server rejects U i service request; if RT i ≥ δ , j i =1, the LBS server is starting with U i as a center, r To broadcast verification requirements to nearby users within the radius, all observers must return the observation results within the valid time; radius r It can be dynamically adjusted according to the user's activity range; if there are more users in the car-hailing system, the radius r is specified as a smaller value and vice versa; Step3, U i to the radius r The observers in the broadcast verification help; Step4, the observers measure the received VH[i] signal strength to estimate with U i distance; Step 5, the LBS server sends U j returns a result notification, final i It is the last service decision of the LBS server; it has the advantages of high efficiency, low latency, identifying dishonest users, and motivating selfish users.

Description

technical field [0001] The invention belongs to the technical field of online car-hailing position identification, and in particular relates to a false position identification method applied to an online car-hailing system. Background technique [0002] In recent years, car-hailing has emerged as a new trend in the field of transportation systems. Its emergence stems from the support and guidance of national policies, as well as the support of emerging technologies such as mobile Internet, big data, and the Internet of Things. [0003] Car-hailing is a case of combining emerging concepts with traditional industries. It combines information technology and digital taxis to change people's traditional way of taking taxis. Users don't have to wait on the roadside for a car that doesn't know when it will come. Reserving a car online brings a lot of traversal to people's travel, and at the same time alleviates the problem of 'difficulty in getting a taxi'. [0004] The online car...
