Title (EN) WARRANTABLE TASK ALLOCATION SYSTEM AND METHOD FOR PRIVACY PROTECTED SPATIAL CROWDSOURCING
(FR) SYSTÈME D'ATTRIBUTION DE TÂCHES JUSTIFIABLES ET PROCÉDÉ D'EXTERNALISATION OUVERTE SPATIALE À CONFIDENTIALITÉ PROTÉGÉE
(ZH) 一种接受保证的隐私保护空间众包任务分配系统及方法
Abstract:
(EN) Disclosed are a warrantable task allocation system and method for privacy protected spatial crowdsourcing, comprising an SC server, a cryptographic service provider, a spatial task requester and a worker, wherein the cryptographic service provider generates a key and uses a Paillier cipher code and an ElGamal cryptosystem; the spatial task requester establishes spatial tasks, and returns task locations to the SC server; the SC server encrypts the task locations, and each worker calculates the distance between the task locations and the position of the worker; the velocity of each worker is encrypted and sent to the SC server, and each worker calculates the travel time thereof, encrypts the travel time and sends the travel time to the SC server; the SC server calculates winning workers with the help of the cryptographic service provider, the cryptographic service provider encrypts a winner set containing a plurality of winners and returns same to the SC server; and the SC server broadcasts the encrypted task locations to all workers, and the winning worker arrives at an appointed position for performance of the task. By the invention, the privacy of two parties is protected in spatial crowdsourcing and the calculation cost is greatly reduced, which can ensure the tasks are accepted in a high probability.
(FR) L'invention concerne un système d'attribution de tâche justifiable et un procédé d'externalisation ouverte spatiale à confidentialité protégée, comprenant un serveur SC, un prestataire de service cryptographique, un demandeur de tâche spatiale et un travailleur, le prestataire de service cryptographique générant une clé et utilisant un code de chiffrage de Paillier et un système cryptographique d'ElGamal ; le demandeur de tâche spatiale établit des tâches spatiales et renvoie des localisations de tâche au serveur SC ; le serveur SC crypte les emplacements de tâche et chaque travailleur calcule la distance entre les localisations de tâche et la position du travailleur ; la vitesse de chaque travailleur est cryptée et envoyée au serveur SC et chaque travailleur calcule son temps de déplacement, crypte le temps de déplacement et envoie le temps de déplacement au serveur SC ; le serveur SC calcule des travailleurs gagnants à l'aide du prestataire de service cryptographique, le prestataire de service cryptographique crypte un ensemble gagnant contenant une pluralité de gagnants et les renvoie au serveur SC ; et le serveur SC diffuse les localisations de tâches cryptées à tous les travailleurs et le travailleur gagnant arrive à une position désignée pour réaliser la tâche. Grâce à l'invention, la confidentialité de deux parties est protégée dans l'externalisation ouverte spatiale et le coût de calcul est fortement réduit, ce qui peut garantir que les tâches soient acceptées selon une probabilité élevée.
(ZH) 本发明公开了一种接受保证的隐私保护空间众包任务分配系统及方法,包括SC服务器、加密服务提供者、空间任务请求者和工人;加密服务提供者生成密钥,采用Paillier密码和ElGamal密码系统;空间任务请求者创建空间任务,将任务位置返回SC服务器;SC服务器加密任务位置,每个工人计算任务位置与工人位置的距离;每个工人的速度被加密发送SC服务器,每个工人计算其行进时间,加密后发送给SC服务器;SC服务器借助加密服务提供者计算获胜工人,加密服务提供者将含有多名获胜者的获胜者集加密后返回SC服务器;SC服务器加密任务位置向所有工人广播,获胜工人到达指定位置执行任务。本发明在空间众包中实现双方隐私保护,计算成本大大降低,能保证任务被高概率的接受。
