The IEEE International Carnahan Conference on Security Technology (ICCST) is an annual conference sponsored by a number of international organizations that have a sincere interest in creating an open forum for the exchange of information related to security technology. The ICCST is directed toward the research and development aspects of electronic security technology, including the operational testing of the technology. It establishes a forum for the exchange of ideas and dissemination of information on both new and existing technology. Conference participants are stimulated to consider the impact of their work on society. The Conference is an interchange of knowledge through the presentation of learned papers that have been selected by the ICCST organizing committee. It is where engineers, physicists, scientists, security professionals and social scientists share with each other the results of their research and development on crime countermeasures. The ICCST also provides a basis for long range support and assistance to authorities and agencies responsible for security, safety and law enforcement in the use of available and future technology. A conscientious effort is made to communicate the significance of developments to other interested groups. Liaison is maintained with professional societies and information media not especially related to engineering. The ICCST has existed for longer than any other conference, anywhere in the world, on this subject. In addition, it has continuously documented the advances in security technology through its proceedings, published beginning with the 1968 conference.
