Design of Dynamic and Personalized Deception: A Research Framework and New Insights

Deceptive defense techniques (e.g., intrusion detection, firewalls, honeypots, honeynets) are commonly used to prevent cyberattacks. However, most current defense techniques are generic and static, and are often learned and exploited by attackers. It is important to advance from static to dynamic forms of defense that can actively adapt a defense strategy according to the actions taken by individual attackers during an active attack. Our novel research approach relies on cognitive models and experimental games: Cognitive models aim at replicating an attacker’s behavior allowing the creation of personalized, dynamic deceptive defense strategies; experimental games help study human actions, calibrate cognitive models, and validate deceptive strategies. In this paper we offer the following contributions: (i) a general research framework for the design of dynamic, adaptive and personalized deception strategies for cyberdefense; (ii) a summary of major insights from experiments and cognitive models developed for security games of increased complexity; and (iii) a taxonomy of potential deception strategies derived from our research program so far

From 11.07.10 to 16.07.10, Dagstuhl Seminar 10281 ``Dynamically Reconfigurable Architectures \u27\u27 was held in Schloss Dagstuhl~--~Leibniz Center for Informatics. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar as well as abstracts of seminar results and ideas are put together in this paper. The first section describes the seminar topics and goals in general. Links to extended abstracts or full papers are provided, if available

Empirical Study of Car License Plates Recognition

The number of vehicles on the road has increased drastically in recent years. The license plate is an identity card for a vehicle. It can map to the owner and further information about vehicle. License plate information is useful to help traffic management systems. For example, traffic management systems can check for vehicles moving at speeds not permitted by law and can also be installed in parking areas to se-cure the entrance or exit way for vehicles. License plate recognition algorithms have been proposed by many researchers. License plate recognition requires license plate detection, segmentation, and charac-ters recognition. The algorithm detects the position of a license plate and extracts the characters. Various license plate recognition algorithms have been implemented, and each algorithm has its strengths and weaknesses. In this research, I implement three algorithms for detecting license plates, three algorithms for segmenting license plates, and two algorithms for recognizing license plate characters. I evaluate each of these algorithms on the same two datasets, one from Greece and one from Thailand. For detecting li-cense plates, the best result is obtained by a Haar cascade algorithm. After the best result of license plate detection is obtained, for the segmentation part a Laplacian based method has the highest accuracy. Last, the license plate recognition experiment shows that a neural network has better accuracy than other algo-rithm. I summarize and analyze the overall performance of each method for comparison
