Malicious software (Malware) in form of Internet worms, computer viruses, and trojan horses poses a major threat to the security of network systems. Identification of malware variants provides great benefit in early detection. Taking into account that variants of malware families share similar functions reflecting its origin and purpose, we propose a method focusing on the features of functions that...
To defend a network system from security risks, intrusion detection systems (IDSs) have been playing an important role in recent years. There are two types of detection algorithms of IDSs: misuse detection and anomaly detection. Because misuse detection is based on a signature which is created from the features of attack traffic by security experts, it can achieve accurate and stable detection. However,...
This paper discusses the vision-based UAV formation flight methods, describes the critical section-formation guidance, moving object extracting, object tracking in detail. At the same time, we propose a real-time video drawing method to apply to flying vehicle object extracting, and introduce the unscented Kalman filtering(UKF) into object tracking to improve the often-used extended Kalman filtering(EKF)...
