通过对基于位置的服务( LBS) 请求的用户及候选者身份进行匿名化处理,利用 DTW 算法依次计算出所有候选者与发起者在一定时间间隔内的轨迹相似值,从中选出最优相似轨迹的候选者替代真实用户请求 LBS 服务,从而实现用户身份与位置的隐私保护. |
Through anonymizing the identities of user and candidates who request location-based service ( LBS) ,and calculating the trajectory similarity between all candidates andthe initiator within acertain period of time by using the DTW algorithm,then choosing the candidate withthe optimal trajectory similarity to replace real user in requesting LBS,the real user privacy informationabout identity and location is effectively protected. |
