[Abstract]:With the rapid development of wireless communication and mobile computing technology, GPS and Beidou global positioning navigation systems are widely used. The convenient location acquisition method has given birth to a large number of space-time trajectory data describing mobile objects (such as people, vehicles and animals). With the rapid growth of the social network service market and fierce competition, the current social network services tend to be mobile to form mobile social network. In mobile social networks, people with common interests use mobile devices such as mobile phones or tablets to communicate, allowing users to track and share location-related information at any time. Massive spatiotemporal data in mobile social networks bring new opportunities to study the mobile behavior of objects in mobile social networks. In this paper, a novel method of user mobility model construction and similarity measurement in mobile social networks is proposed to meet the needs of massive spatio-temporal data analysis in mobile social networks. In addition, in order to meet the requirements of real-time security monitoring, this paper proposes an algorithm based on Hausdorff distance based grid sequence clustering to detect the abnormal trajectory of large-scale trajectory data. In this paper, the real data set GeoLife published by Microsoft Asia Research Institute is used to evaluate the effectiveness and real-time performance of the proposed algorithm. The experimental results show that the proposed algorithm can effectively construct the mobile model of mobile users and is superior to the traditional similarity measurement method in the accuracy of similarity measurement. In addition, the anomaly trajectory detection algorithm proposed in this paper not only effectively detects abnormal behavior, but also greatly reduces the time consumption of the traditional anomaly detection algorithm, and makes a certain contribution to the on-line real-time anomaly detection.
