Malicious software poses a great risk to critical infrastructure. Researchers have proposed numerous ways to analyze malware behavior in order to understand and respond to this threat. However, only little attention has been paid to the organization of the malware analysis process itself. In this paper we present the Malware Analysis and Storage System (MASS), a novel framework for malware analysis...
Remote experimentation has long conflicted with security policies imposed by networks administrators. To provide external access to experiment servers in a university, security measures are demanded. Such leads to an excessive dependency on the IT departments for services configuration and maintenance. In the present work, modifications in ISA/ELSA architecture are proposed to circumvent those problems...
The multi-user collaboration operation examination system based on the TCP is designed to solve the limitation of collaborative operations in previous novel marine engine virtual reality simulation platform system. This paper will use the design of the communication mode, operation of information processing and the establishment of evaluation module to realize the different terminals' collaborative...
Kaleido is a novel data system for multi-device synchronization. According to the theories of conflict-free replicated data types, Kaleido enables clients to synchronize replicated data types with operations, and gurantees high availability and eventual consistency. Implemented as a back-end as a service, Kaleido server is scalable so as to deal with a huge amount of requests from massive clients...
Geo-distributed clouds are composed of several virtual machine servers scattered over sites interconnected by a wide area network. In this scenario, the traffic generated by control messages can be prohibitive, because of the high bandwidth costs of these networks. This paper evaluates the impact of this type of traffic in the scalability of the cloud. Based on experiments with the OpenStack orchestrator,...
Curricula of the Universities and especially of the Universities of Applied Sciences should be, in the best case, developed in such way, that graduates' knowledge should reflect contemporary requirements of the industry, without to losing the assertion of universality as the central perspective of the higher education. This awareness is often identified, but in the real case, the organization of the...
In this demo, we present Coagmento 2.0, a Web-based, open-source platform that provides support for one working in individual or group projects spanning multiple sessions that involve looking for, collecting, and synthesizing information. The system also provides a highly customizable platform for researchers who want to investigate individual and group information seeking behaviors in a lab or a...
Hakkas tangible culture heritage are distributed in different areas widely. Management and preservation of Hakka cultural digital resources are achieved in different regions that has formed a new “information isolated island”. In order to improve sharing and utilizing of these data in different regions, service aggregation and database middleware technology are brought into data collaborative services...
We design a collaborative e-learning system for stable operation in an unstable environment of developing countries. The proposed system is used for providing a collaborative learning among local schools of rural area in Nepal. The stable operation of the system is realized by the redundant robustness in three different levels: network arrangement, energy management,, replicative database. In this...
Accurate sensing of the spectrum is one of the prime requirements for efficient functioning of cognitive Radio systems. But accurate sensing is a complex process, as signals of different modulations, coding methods and power levels along with fading and noise are present in the given radio environment. Collaborative sensing techniques can help to improve the sensing accuracy. One such collaborative...
Collaborative filtering is one of the most successful approaches to building recommendation system. However, it still has some known disadvantages. One of them is called cold start problem caused by lack of user's historical data. Another problem appeared because mobile technology develops in high speed. The phenomenon that users change their taste according to their position quickly in mobile environment...
Mobile users access location services from a location based server. While doing so, the user's privacy is at risk. The server has access to all details about the user. Example the recently visited places, the type of information he accesses. We have presented synergetic technique to safeguard location privacy of users accessing location-based services via mobile devices. Mobile devices have a capability...
The modern era witnesses the evolution of handheld devices from a simple communication medium to a sophisticated information access platform. Coupling it with intelligent recommendation techniques can transform it to an essential companion for users during their travel, purchases and other routine transactions. A recommender system extracts personalized information relevant to users, thereby limiting...
The patent information data has the characteristics of massive, open, scattered, but the lack of a well-designed platform which can make good use of these data is still a problem. The platform introduced in this paper which is mainly tailored for patent agencies can organize resource information, provide analysis report, and promote business cooperation. Based on cloud architecture, the platform has...
The goal of this study was to investigate the efficient use of role-taking embodied conversational agents in the facilitation of creative cognition during collaborative activities. Two factors were investigated through an experimental design addressing the number of conversational agents (one vs. two), and method of communication (voice vs. text). Participants engaged in a simple interpretation game...
Aiming at the development demand of the equipment command information system in modern war, the architecture of distributed equipment command information system Based on mobile agent is proposed. The main system components and workflows are presented in detail, as well as the migration communication of mobile agent and the system security guarantee in the system realization are analyzed in emphasis...
We are developing a collaborative web application for editing PDF documents using web browsers. Our system enables users to edit the same document in real-time. Users can share annotations on papers in real-time on web browsers. One of the advantages of our system is very high availability. Users only need to have their own web browsers. To improve the usability of our system, we need to consider...
Many modern information systems require some form of collaboration among peers. To address these needs, existing approaches tend to build a layer on top of traditional database technologies that implements a specific distribution model. In contrast, our aim was to integrate concepts into a database that would provide native support for data sharing while allowing developers the flexibility of configuring...
In this paper, we present a concept for developing applications that allow users to work synchronously together while being able to use asynchronous features, such as work resumption from any point in time. Therefore, we formulate abstract requirements for a protocol realizing the introduced approach. Furthermore, an architecture for deployment is outlined. We show three different applications - all...
Telehealth systems represent an ICT solution for delivering health services to the patients from a distance (Patient to Doctor/Doctor to Patient systems, P2D and D2P) or facilitating the consultation between the health professionals (Doctor to Doctor systems, D2D). Whether P2D/D2P systems aim at defining an interaction between the two involved figures crossing the boundaries of the hospital, D2D systems...
