Information technology and modern challenges in civil protection create many questions concerning infrastructure security and reliability. In particular, mobile communications and the spread of mobile phones among citizens offer new opportunities of fine-grained disaster management using location based services (LBS). At the same time, location based services are regarded as very privacy-invading, and are regulated in many countries by law. In our article, we analyze the requirements of a LBS based disaster management scenario and propose a solution on how to build a privacy-friendly, multilaterally secure disaster management infrastructure based on robust, mobile phone infrastructures with high reachability of citizens and the possibility to manage disaster specialists.
