A Framework for Mobile Forensic Readiness in Yemen

One of the most important inventions of the 20th century is the mobile phone. In addition to making and receiving phone calls, a mobile phone can be used for texting, gaming, taking photos, recording movies, and accessing the internet, among many other things. This paper develops a framework for mobile forensic readiness in Yemen. In addition, mobile forensic readiness (MFR) aims to know the level of readiness for mobile forensic in Yemen, the level of mobile forensic factors in Yemen, and factors that affect the readiness for mobile forensic in Yemen. The main goal of forensic preparedness is to maximize an organization's capacity for establishing the viability of conducting forensic investigations and for accessing digital evidence at the lowest possible cost of an inquiry. Fundamentally, the primary goal of forensic preparation is to guarantee that the evidence is pertinent and comprehensive enough for the forensic investigation. The research is descriptive and collects indicators of MFR from literature review and 110 questionnaire that given to the Yemeni criminal investigation bureau employees, technology users, public prosecutor office employees. Furthermore, through the interviews were done with the police station managers and their employees. However, the returned questionnaires were 101. Statistical Package for the Social Sciences (SPSS) was used to analyze and test the data through mean, standard deviation, and one sample T- test. Moreover, SPSS AMOS was used to design the framework. All mentioned hypotheses were tested using regression, T- Value, Beta, P- value, and R-square. Therefore, the results show that all hypotheses were supported. This paper develops a framework for mobile forensic which reveals if we have a suitable infrastructure for mobile forensic and increase the awareness of mobile forensic which assists the experts to recover and analyze data. Furthermore, this research increases the potential use of digital evidence and increases the trust in the mobile forensic process.

Latent fingermark development using low-vacuum vaporization of ninhydrin

The vacuum technique is a method of vaporizing a solid material to its gas phase, helping deposit reagents gently on target surfaces to develop latent fingermarks. However, this application is rarely reported in the literature. In this study, a homemade fume hood with a built-in vacuum control system and programmable heating system designed by the Taiwan Criminal Investigation Bureau is introduced. Factors that affect the instrument's performance in developing fingermarks are discussed, including the quantity of chemicals for vaporization, heating program arrangement, and paper of different materials.The results show that fingermarks are effectively developed by vaporizing solid ninhydrin. This would be an alternative application in selecting a solvent-free method for protecting the environment and reducing health hazards in the lab. In terms of the heating program, the result indicates that under a low-vacuum condition (50mTorr), 80–90°C is a suitable temperature range for ninhydrin vaporization, allowing ninhydrin to be vaporized without bumping and waste. In terms of the performance on different material papers, this instrument demonstrates its capacity by developing latent fingermarks on thermal paper without discoloration or damaging the original writing, and the same results are also observed on Taiwan and United States banknotes. However, a coherent result could be hardly obtained using the same vaporization setting because different banknotes have their own surface features and water absorption ability or other unique factors may influence the effect of ninhydrin deposition. This study provides a reliable application for developing latent fingermarks without using solvents, and it is also expected to contribute to environmental protection along with the trend of green chemistry technology.

Comparison of immunostrips with mouse bioassay and bacterial culture in detecting botulinum toxins in bottles from suspected Taiwan high-speed rail bomber

In April 2013, a bomb-threat incident occurred on the Taiwan high-speed railway. Two suspects claimed to have placed explosive devices on a high-speed train and outside a lawmaker’s office. Afterward, the Criminal Investigation Bureau also found several bottles in the main suspect’s apartment labeled “botulinum toxin.” The Institute of Preventive Medicine was entrusted by the Institute of Forensic Medicine, Ministry of Justice, to verify whether the bottles contained botulinum neurotoxin (BoNT). Three different analyses, including rapid detection strips, toxin neutralization tests, and bacterial culture, were processed. The results provided conclusive evidence that botulinum neurotoxin type A (BoNT/A) was present in the samples. This study demonstrated that the BoNT/A strip assay is an excellent method for BoNT/A detection, and has potential use as an early warning tool in screening of food products for botulinum toxins.

A Real-time Crime Detection System Based on Lawful Interception - A Case Study of MSN Messenger

In recent years, the number of online crimes (e.g., the various emerging scams and criminal schemes) has increased. Online crime suspects utilize the anonymous nature of web to disguise their identity through various methods and evade detection and surveillance from law enforcement agencies. This study proposes an effective lawful interception system, Real-time Crime Detection System (RCDS), which includes Criminal Investigation Bureau (CIB), Internet Service Providers (ISP), and Network Interception Server (NIS) to establish a legally sanctioned lawful interception process which can collect and store evidence for criminal detection in real time. We provide a case study of MSN Messenger to describe the MSN Protocol (MSNP), information flow process, and lawful interception methodologies. The RCDS can provide criminal detection and surveillance services for MSN to obtain criminal communication records in turn reducing online criminal activities.

Education Improvement in Construction Ethics

Billions of new Taiwan dollars NTD; about 30 NTD 1 USD are invested in infrastructure construction by public agencies and private sectors each year in Taiwan. However, some projects have been plagued with poor workmanship, structural failure, and resultant deaths. In numerous cases, innocent people suffer and blame the actions of predatory constructors. Although some unprincipled contractors and corrupt government officials—or even high-ranking officials—have been sentenced to jail, cases have also occurred in which outstanding members of the profession have been imprisoned because of a lack of understanding of engineering ethics and professional standards. For example, ZeYuan Wu, former chief of the Department of Residential and Urban Development in the Taiwan Province Government, was charged with corruption during the construction of a pumping station at a sewage treatment plant in Taipei County. Taiwan Panchiao District Court judges sentenced the former Chief Wu to life in prison in 1996 Law and Regulations Retrieving System 1996 . Nevertheless, Wu did not agree with the judgment and appealed to a higher court. In the meantime, he applied for a visit abroad and then went abroad. He never went back, even when his mother died in Taiwan. Since then, the Criminal Investigation Bureau has ordered the arrest of Wu and placed him on the most-wanted list, with a reward of ten million NTD National Police Agency 2006 . This is a total loss to both the individual and to society. Civil engineers should have ethical responsibilities not only to clients but also to those who are exposed to their structures Robinson 2000 . Public safety is endangered if unprofessional construction practices cannot be stopped Barkdoll 1998 . Even one single severe violation of ethical behavior can damage the whole profession Riihela and Vayrynen 1997 . Ethics is one of the most important problems for engineering education Vesilind 2001 . Engineering students should not only be educated in physical science and engineering concepts but also

Cybercrime & Cybercriminals: An Overview of the Taiwan Experience

This paper explores the increasing number of cybercrime cases in Taiwan and examines the demographic characteristics of those responsible for this criminal activity. The report is based upon data taken from the Criminal Investigation Bureau of Taiwan’s cybercrime database over the interval of 1999 through 2004. The paper defines cybercrime, analyses cybercrime case statistics and examines profiles of cybercrime suspects’ characteristics. The findings show that of all types of cybercrimes committed over the past six years, the top five are distributing messages regarding sex trading or trading sex on the Internet, Internet fraud, larceny, cyber piracy and cyber pornography. As for suspect characteristics, the findings show that 81.1% were male; 45.5% had some senior high school; 63.1% acted independently; 23.7% were currently enrolled students; and 29.1% were in the 18-23 age bracket, which was the majority group. For those enrolled student cybercrime suspects, the findings show that the percentage of junior high school and senior high school student suspects constituted 69.0% (2002), 76.1% (2003) and 62.7% (2004) of cybercrime suspects in their respective years. The high rate shows that the number of currently enrolled students suspected of involvement in cybercrime is cause for concern. Finally, this paper offers recommendations to governments, social agencies, schools, and researchers in their efforts to reduce cybercrime.

The Impact of an Antiamphetamine Law on Juvenile Delinquency in Taiwan

In October 1990, Taiwan changed its criminal code on amphetamines, making possession and use of such substances a punishable act. Strong government intervention against amphetamines-related offenses supported by an uncritical general public has created an increasing criminal population. This article focuses on how the newly enacted antiamphetamines law affects the extent and nature ofjuvenile delinquency in Taiwan. Data arefrom the Crime Statistics compiled by the Criminal Investigation Bureau. The study found that the volume of delinquency has increased since 1990, the average age of official delinquents has not changed, and the gender ratio in delinquency involvement has decreased.
