The Security Challenges, Issues and Countermeasures in Spatiotemporal Data: A Survey

Abstract

In recent decades, the Wireless Sensor Network (WSN) is used in potential areas like battlefield surveillance, border security surveillance, disaster management, forest monitoring system, ocean surveillance and real time navigation system. The WSN’s generates a large amount of spatiotemporal data. Providing the data security in WSN is itself challenging task. So when the spatiotemporal data needs to be handled, the security mechanisms demands more careful strategies to be adopted. In order to provide security for spatiotemporal data, the following concepts such as secure access control, log management, security model, activity pattern, secure range queries for legitimate users, key management, privacy preservations and secure spatiotemporal data applications are studied here. In this paper, to facilitate an effective security mechanism for spatiotemporal data in WSN, the above said security related mechanisms are discussed in detail.
