Cybercrime and Online Safety in Cyberspace
Cybercrime is essentially a transnational crime with a ‘modus operandi’ that exploits inter-state differences in the capacity to respond to such crime, and appears in the same company as such powerful global concerns as civil war, genocide and poverty (United Nations 2004). This transnational character provides cybercriminals, especially organized crime (OC), with the agility to avoid counter-measures even when implemented by capable actors (Brenner 2002, 2006; Council of Europe 2004). Although some have questioned the existence of organized criminal activities in cyberspace, several studies have noted the potential and actual synergy between organized crime and cyberspace in recent years. This paper outlines some of the issues and problems in respect to the role of OC in cybercrime.
Cybercrime in Asia: Trends and Challenges
The rapid growth in Internet use in Asia, including a tenfold or more increases in access in China, Indonesia, and India since 2002 has also been accompanied by significant increases in cybercrime. The development of commercial-scale exploit toolkits and criminal networks that focus on monetization of malware has amplified the risks of cybercrime. The law-enforcement response in Asia is briefly reviewed in the context of the 2001 Council of Europe’s Cybercrime (Budapest) Convention. We describe the nature of cybercrime (including both “hate” or content and “crime-ware” such as botnets) and compare the laws and regulations in Asian states with the provisions of the Convention. The challenges faced in developing effective cross-national policing of cybercrime in Asia are also addressed as problems emerge around cloud computing, social media, wireless/smart phone applications and other innovations in digital technology.
Application of Automatic Tracking Correlation Filtering in Motored Spindle Dynamic Balancing
According to the information characteristics of the dynamic imbalance signal and the definition of correlation function,the principles and algorithm of relevant filter with automatic tracking is given.In labview development system,based on the principles of relevant filter with automatic tracking,the graphics programming of extracting the dynamic imbalance signal is developed.With this programming,the vibration signal including different frequency harmonic signals and noise is processed by simulation and on-site experiment.The results show that: through relevant filter with automatic tracking,the dynamic imbalance signal under different rotating speed can be extracted accurately,and it can meet the requirement of motored spindle dynamic balancing measurement.
