Thus, not only GSR but also primer mixtures generated from both reference cartridges and confiscated illegal cartridges were analyzed in this work. The aim of this work is to obtain elemental composition data of primer mixtures of handgun cartridges frequently encountered in Taiwan and to provide procedures for identifying cartridge used in criminal activities through elemental analysis of GSR and primer mixtures of suspected cartridge. Twenty-five kinds of cartridges with noncorrosive primers or lead-free primers were disassembled or test-fired to collect primer mixtures or GSR, respectively. Bullet and propellants of unfired ammunition were removed, the cartridge case was deprimed, and primer mixtures were then recovered. Gunshot residue samples were collected from shooter's hand, spent cartridge case, and target surface after test firing. Both primer mixture and GSR samples were then subjected to SEM/EDX analysis. The results revealed that all of the noncorrosive primer mixtures and GSR generated from cartridges with these primers contained unique elemental composition of lead (Pb), barium (Ba), and antimony (Sb). Only Ba and Sb were detected in two kinds of lead-free primer mixtures and GSR generated from cartridges with these primers, where none of Pb, Ba, and Sb were detected in samples from the other four kinds of lead-free cartridges. Characteristic elements of Pb, Ba, and Sb were detected in all primer and GSR samples collected from illegal cartridges and were not detected in samples from police duty cartridges. These results indicated that lead-free cartridges have not yet been used by criminals in Taiwan. The significant elemental difference between GSRs from different sources is especially useful in identifying possible shooter while the fired bullet is missing.","PeriodicalId":344868,"journal":{"name":"IEEE 37th Annual 2003 International Carnahan Conference onSecurity Technology, 2003.

Access control through authorization is important to a high-secure system in military or government where unauthorized users are not allowed to access secret data. A real application system for the high-secure military workflow is considered. Every particular working activity in the workflow must associate multiattributes. The application system is based on the Petri net model, we define the access control problem in our system as a multiattribute hierarchy environment. A Petri net is represented by a directed, bipartite graph in which nodes are either places (represent conditions) or transitions (represent activities). A token that is located in a place signifies that its condition is true. When all the places to a transition have a token, the transition is enabled. Our problem objective is to assign suitable cryptographic keys to this multiattribute hierarchy. Based on a description on security requirements, our algorithm can verify and generate the keys automatically.","PeriodicalId":344868,"journal":{"name":"IEEE 37th Annual 2003 International Carnahan Conference onSecurity Technology, 2003.

It is important to maintain Internet security system during and after the occurrences to collect evidence and forensics essences by various devices, such as hard disk, system log, firewall, IDS log, processes, as well as Internet connections. It would be even more beneficial to the forensic process if evidence could be established and kept well before such an incident happened. Most government organizations lack sufficient knowledge of security system techniques and they still believe that this technical part of the work belongs to the police. In fact, we cannot guarantee a perfect stage, but at least we can figure out what the problem is and trace where the attack is from, and that is the mission of computer forensics. Schools or institutes that are engaged in research and development of relative security system techniques are doing their own work; thus, capabilities of computer forensics have been dispersed. Therefore, in order to enhance the forensic skill of information and communication security and ability, what we really need is a complete plan so as to integrate the forensic skill of information and communication security and ability.","PeriodicalId":344868,"journal":{"name":"IEEE 37th Annual 2003 International Carnahan Conference onSecurity Technology, 2003.
