The authors consider the use of a CD model to reconstruct a crime scene using the technology of artificial intelligence, with particular reference to gunshot-caused bloodstain evidence. They attempt to incorporate the domain knowledge of mark theory and the experiences of investigators in their expert system, which helps both the investigators and qualifies practitioners to gain enough evidence from the crime scene.<>

Dornier has developed a radar intrusion detection sensor (RADOBS) which largely eliminates environmental and ambient effects such as rain and electromagnetic interference. RADOBS is a monostatic pulse Doppler miniradar for mobile and stationary use. The system can be installed in two versions: RADOBS-R for omnidirectional detection by means of a ring zone and RADOBS-V with a directed sector zone. The detection zones of both versions can be defined precisely to ensure that no alarm is released outside these defined zones.<>

The authors discuss concepts used in developing the CSC (Correctional Services Canada) Duress Alarm Location System (DALS). A block diagram and theory of operation for the system are presented. A sample data and test results for an actual test installation are presented and analyzed. It is concluded that the DALS is able to acknowledge and locate a duress alarm within an indoor environment with useful precision and reliability.<>

Based on the concept of public key distribution (PKD), a new practical design for a secure broadcasting system is proposed. The proposed secure broadcast cryptosystem is based on the Diffie-Hellman public key distribution concept. The communication key is hidden with the RSA scheme. The security of the cryptosystem is therefore the same as that of the RSA scheme. The single key concept is used to reduce the load of additional control messages.<>

A tool for verifying security properties of data is described, based on colored Petri nets. A conceptual data model for complex applications and a mandatory security model based on the principles of Bell-LaPadula are presented. The tool operates on such models, using the Petri net analysis techniques, based on the reachability graph. The absence of interference of sensitive associations, the reachability of information, and the temporal relationships among data access properties are studied, and conditions on the reachability graph are defined, to guarantee that such properties hold in the system.<>

The authors propose a dynamic access control model (DACM) to meet the access control requirements of an environment that frequently changes and adjusts user access privileges and/or target object confidential level. For the DACM, one uses an object-oriented technique to describe the whole model and also to implement its access control mechanism called the dynamic access control system. A real case similar to the DACM has been implemented in the Administration Information System of the Central Police University. The performance shown in this case is quite good from the viewpoint of the end user and system developers/maintainers. The DACM technique can be used to cope with a dynamically changing environment.<>

The role of the passive infrared (PIR) motion detector is reviewed. It is noted that, currently, it is peripheral component of security systems, installed to overlook a specific area. Future needs for integrated building automation systems require more powerful sensors that approach true presence detection, in order to provide the basic information from every room: the presence of people. From such detectors, a complete picture of occupancy of a building is obtained which meets the needs of a security system as well as energy control and safety. A highly sophisticated self-learning sensor technology has been developed for these requirements. Several thousand detectors have been installed over the last few years in various buildings, with excellent results.<>

An alternative approach to applications which need expensive smart cards with cryptoprocessors is suggested. The idea is to perform cryptographic features in special smart card reading devices. Thus, the price of data protection and access control in computing systems and networks may be substantially reduced. In most applications cheap EEPROM smart cards can be used instead of microprocessor cards.<>

A password authentication scheme which can verify remote passwords without the use of a verification table is presented. Each user possesses a smart card which is used for login and authentication, as introduced by A. Shamir (1985). During the login, the user types in his identity and the password associated with his smart card, along with the identity of the other user with whom he wishes to communicate. The smartcard uses a signature scheme to check whether or not the login can be accepted. As well as modifying Shamir's algorithm for the signature scheme checking by using a theorem about relatively prime numbers, one also adds communication timestamps to prevent replaying of a previously intercepted login request.<>
