"Advances in Security Technology" is a specialized book that addresses the latest developments in the field of security technology. In an era where security technology is becoming increasingly specialized and fragmented, this work highlights the common themes and connections between various disciplines. It demonstrates how advancements in one area of security technology can be transferred to other fields. The hybrid approach, which combines ideas from different disciplines to achieve more significant results, is particularly emphasized. This collection includes expanded versions of contributions presented at the International Conference on Security Technology 2008 and the Conference on Advanced Science and Technology 2009. The editors and the international program committee have worked diligently to publish these advancements to promote the exchange and further development of security technology.
