Information Security of Location Estimation - Increasing Trustworthiness

Vulnerabilities of GNSS (Global Navigation Satellite Systems) or non-GNSS based localization include (1) unintended disruptions of the position or timing solution, (2) malicious attack on the physical or virtual infrastructure of the localization engine, (3) theft of information from the localization engine or its associated modules, and (4) loopholes in the policy framework supporting the legal creation and exploitation of location-based applications jeopardizing the privacy of the individual. This paper gives a brief overview to the state-of-the-art in vulnerabilities in localization, including in its technology, security, robustness, privacy, and policy aspects. It discusses the requirements for enhancing the trustworthiness of localization as to overcome a majority of the vulnerabilities. The paper addresses in particular the question of what are the constraints of ensuring continuous logistics of a localization solution and potential solutions. Thus, this paper presents firstly a brief state-of-the-art analysis of vulnerabilities in localization and then focuses on the requirements for enhancing the trustworthiness.
