Surveillance of the sea borders is a very important task for the Border Guard. Monitoring of country maritime border is an important task of the Border Guard. This task can be facilitated with the use of the technology enabling gathering information from distributed sources and its supervision and visualization. This task can be accomplished using a technology that allows to collect information from distributed sensors of different types, unify the collected information, and present the synchronized data. The system presented in the paper is an extension and enhancement of the previously developed distributed map data exchange system. The added functionality allows to supplement the map data with multimedia (telephone and radio calls, video (cameras), photos, files, SMS/SDS) and presentation of current and archival situation on a multi-display screen in the Events Visualization Post. In the paper, the system architecture, functionality and main system elements are described and supported with preliminary analysis and test results.

Non-cryptographic methods for improving real time transmission security and integrity

In this paper we present a few non cryptographic methods for improving the security, integrity and reliability of real time services. The methods presented in this paper apply to real time transmitting systems, which are based on the Peer-to-Peer (P2P) model. A basic idea of the first technique is to use agents for detecting steganographic content in packet headers, so packets with suspicious entries in the IP header fields will be blocked or the fields will be erased. The two other presented techniques are based on reputation and trust systems, so trust and reputation basic definitions, types and modelling methods are shown. Also a simple design scheme of using these mechanisms in a P2P real-time data transmitting infrastructure is presented. Additionally, we describe an idea of path selecting technique, which can be used to avoid paths that are susceptible to eavesdropping.
