In this paper we present an intrusion detection engine comprised of two main elements;firstly, a neural network for the actual detection task and secondly watermarking techniques for protecting the related information that must be exchanged between nodes. In particular, we exploit information visualization and machine learning techniques in order to achieve efficient and effective intrusion detection. In order to avoid possible modification or alteration of the maps produced by the intrusion detection engine, we focus on safeguarding and authenticating them using a novel embedded watermarking method. Previously, we had shown promising results in the intrusion detection task using this system. This paper focuses on the watermarking technique and gives a detailed exposition that includes an experimental evaluation of its quality.

Data mining algorithms have been proved to be useful for the processing of large data sets in order to extract relevant information and knowledge. Such algorithms are also important for analyzing data collected from the users' activity users. One family of such data analysis is that of mining of log files of online applications that register the actions of online users during long periods of time. A relevant objective in this case is to study the behavior of online users and feedback the design processes of online applications to provide better usability and adaption to users' preferences. The context of this work is that of a virtual campus in which thousands of students and tutors carry out the learning and teaching activity using online applications. The information stored in log files of virtual campuses tend to be large, complex and heterogeneous in nature. Hence, their mining requires both efficient and intelligent processing and analysis of user interaction data during long-term learning activities. In this paper, we present a bi-clustering algorithm for processing large log data sets from the online daily activity of students in a real virtual campus. Our approach is useful to extract relevant knowledge about user activity such as navigation patterns, activities performed as well as to study time parameters related to such activities. The extracted information can be useful not only to students and tutors to stimulate and improve their experience when interacting with the system but also to the designers and developers of the virtual campus in order to better support the online teaching and learning.

The rapid growth of computer technologies and the advent of the World Wide Web have increased the amount and the complexity of multimedia information. A content-based image retrieval (CBIR) system has been developed as an efficient image retrieval tool, whereby the user can provide their query to the system to allow it to retrieve the user's desired image from the image database. However, the traditional relevance feedback of CBIR has some limitations that will decrease the performance of the CBIR system, such as the imbalance of training-set problem, classification problem, limited information from user problem, and insufficient training-set problem. Therefore, in this study, we proposed an enhanced relevance-feedback method to support the user query based on the representative image selection and weight ranking of the images retrieved. The support vector machine (SVM) has been used to support the learning process to reduce the semantic gap between the user and the CBIR system. From these experiments, the proposed learning method has enabled users to improve their search results based on the performance of CBIR system. In addition, the experiments also proved that by solving the imbalance training set issue, the performance of CBIR could be improved.

The educational material which can be used under various situations has multiple variants even for one lecture theme. The lecturer often constructs and manages the variants separately with ad hoc reuse. This scheme of reuse raises a problem of consistency among multiple variants. To resolve this problem, we introduce concept of software product line engineering into educational material management. Separation of common parts and variable parts in the educational material enable generation of variants depending on reuse scene. We design and implement a generation tool to evaluate the scheme.
