Mechanical Design of a Device for Automatic Implementation of Security Features on Passports

In general, biometrics is concerned with the identification and verification of a person's identity. The biometric passport is one of the forms of identification for establishing an individual's identity in their home nation and abroad. Various national and international regulatory and security requirements govern the size, content, and structure of biometric passports. The mechanical design of a biometric passport marking device is the subject of this research article. The purpose of this research is to generate a practical design that meets all legal and safety standards. The best option is chosen from a variety of design concepts.

An alternative to fortified schools: Using crime prevention through environmental design (CPTED) to balance student safety and psychological well‐being

AbstractIn response to tragic school shootings, heightened attention has been devoted to making schools safer through the implementation of security features. However, excessive security measures have a negative impact on school climate, student functioning, and academic achievement. Therefore, there is a critical need to design schools that are safe and secure, yet also welcoming and comfortable. As a promising approach in this regard, crime prevention through environmental design (CPTED) is an architectural philosophy that aims to deter criminal or antisocial behavior through environmental design, and it includes a focus on natural surveillance, access control, and territorial reinforcement. This review discusses pertinent effects of the school environment on student outcomes, extant research on the impact of visible security measures, the relationship between students’ perceptions of safety and academic functioning, and how using CPTED could concomitantly address the physical safety and psychological comfort of students at school.

Security-Performance Tradeoffs in a Class of Wireless Network Scenarios

There has been an extensive and widespread deployment of wireless local area networks (WLANs) for information access. The transmission, being of a broadcast nature, is vulnerable to security threats and hence, the aspect of security provisioning in these networks has assumed an important dimension. The security of the transmitted data over a wireless channel aims at protecting the data from unauthorized access. The objective is achieved by providing advanced security mechanisms. Implementing strong security mechanisms however, affects the throughput performance and increases the complexity of the communication system. In this paper, we investigate the security performance of a WLAN based on IEEE 802.11b/g/n standards on an experimental testbed in congested and uncongested networks in a single and multi-client environment. Experimental results are obtained for a layered security model encompassing nine security protocols in terms of throughput, response time, and encryption overhead. The performance impact of transmission control protocol and user datagram protocol traffic streams on secure wireless networks has also been studied. Through numerical results obtained from the testbed, we have presented quantitative and realistic findings for both security mechanisms as well as network performance. The tradeoff between the strength of the security protocol and the associated performance is analyzed through computer simulation results. The present real time analysis enables the network designers to make intelligent choices about the implementation of security features and the perceived network performance for a given application scenario.
