The paper discusses the security issues in the context of an open, multimodal, end-to-end tracking and tracing system. A brief overview of the system architecture is followed by an analysis of potential security threats to the system. These threats are countered by a security concept involving a two-stage authentication process and an advanced access control scheme. Conventional access control schemes either provide access to accurate information or restrict access completely. This is not appropriate for a tracking and tracing system and thus a scheme based on changing the accuracy of information is presented.
