We propose a novel personalized recommendation model for social network users based on location computing. The novelty of our model is that we deal with the location based recommendation by combing logistic regression with collaborative filtering method. The logistic regression is used to train the weights of items' features, i.e., the recommendation sort list. On the other hand, the collaborative...
Nowadays cloud services have become a cost-effective platform for sharing data and performing large scale computations. As outsourcing data to a third party involves security and privacy concerns, data should be sent to the cloud in encrypted form. To handle access control on encrypted cloud data, Ciphertext-Policy Attribute-based Encryption (CP-ABE) has become very popular. In this scheme data can...
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...
Active learning has demonstrated value in STEM education and various meta analyses show improvements in student performance when making use of active learning pedagogy and active learning classrooms. One limiting factor to extending the reach of active learning is cost. Many models for state-of-the-art active learning environments make use of tools and infrastructure through which students can connect...
Nowadays, collaborative systems and applications are widely used to allow multiple users to work together in order to achieve one same goal. In the field of virtual and augmented realities, such collaboration is often sought to effectuate complex activities in some relevant experiences. Users can share virtual objects, but most importantly, they use collaborative 3D interaction, visualize their objects...
With the ever improving availability of social media platforms, the internet and mobile devices, crowdsourcing becomes a popular business development strategy in outsourcing various tasks to outside crowds. In product design and development, one of the crowdsourcing objectives is to engage various users into human-centered design processes and outsource tasks to crowds for better design efficiency,...
Service infrastructures operated by different operators with own policies are being federated to agglomerate various services. To join a federation, an operator must comply with a federation agreement. As a result, it takes time for the operator to check the consistency between own policies and the agreement, and to establish a network connection to federation's infrastructure. To ease these concerns,...
The use of online collaboration in developing documents is still not popular in Indonesian public institutions. Therefore, it takes many budgets and much time to make a public document. Meanwhile, the government should improve the quality of public services effectively and efficiently. This paper discusses the comparison of three selected document management system (DMS) features, Doccept, eFileCabinet,...
We consider the case of spreadsheet based workgroup collaboration, in which users cooperate through spreadsheets. While spreadsheet exchange through email and shared directories is still the most common way to share data, spreadsheet sharing in the Cloud is rapidly spreading, leveraging the evolution of office tools toward delocalized system over the Cloud. In this paper we observe that spreadsheet...
Cloud-based ERP (Enterprise Resource Planning) Platform is a tendency to facilitate collaboration across Small and Medium-sized Enterprises (SMEs) in the industrial supply chain. However, fast and smooth accessibility to the cloud resource is a vital challenge due to efficiency, reliability, security and other critical issues. This paper presents the development of a mobile application by using web...
The advances in computational techniques both from a software and hardware viewpoint lead to the development of projects whose complexity could be quite challenging, e.g., biomedical simulations. In order to deal with the increased demand of computational power many collaborative approaches have been proposed in order apply proper partitioning strategy able to assign pieces of execution to a crowd...
In the analysis of digital content consumption, session progress provides a good alternative to using manual ratings for measuring user engagement. A good prediction of session progress is useful for optimizing and personalizing the end-user experience. Most prevalent methods of predicting session progress are based on matrix completion and only consider the interaction among users and videos, while...
Public cultural sharing service plays an important role in the public cultural platform. The recommender systems can bring users useful cultural resources and information. For safety and security reasons of the cultural resources, the external applications are not allowed to directly access the original resource data stored in the cultural databases by sending recommendation requests. The cultural...
Ardoises is a formal modeling platform, that allows its users to collaboratively define formalisms and models of these formalisms. This article presents the algorithm and protocol used for collaborative editing. Its main characteristics are collaborative editing between several users and/or tools, interactivity with low latency through optimistic changes, and optional locking policies. The paper explains...
We present LAVEA, a system built for edge computing, which offloads computation tasks between clients and edge nodes, collaborates nearby edge nodes, to provide low-latency video analytics at places closer to the users. We have utilized an edge-first design to minimize the response time, and compared various task placement schemes tailed for inter-edge collaboration. Our results reveal that the client-edge...
With the rapid development of the social networks, Collaborative Filtering (CF)-based recommender systems have been increasingly prevalent and become widely accepted by users. The CF-based techniques generate recommendations by collecting privacy sensitive data from users. Usually, the users are sensitive to disclosure of personal information and, consequently, there are unavoidable security concerns...
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...
In this work we focus on integrity and consistency of data accessed and manipulated by multiple collaborating users, and stored in an (untrusted) hosted service. This is a problem, aspects of which have been studied in isolation in hitherto distinctcommunities. Consistency is one of the cardinal problems of distributed computing. Integrity of hosted data has been studied over the last decade, and...
This paper proposes a collaborative in-network caching method for multi-path routing. In-network caching allows routers in networks to store contents in their caches and users can download the contents from the routers in addition to content servers. In such a situation, the proposed method introduces a joint optimization problem of in-network caching and multi-path routing, which is formulated as...
Cloud gaming will make high quality gaming more accessible to everyone. It not only relieves users of the constant need to upgrade their hardware, but also makes it possible to enjoy high quality gaming on a variety of devices. Although cloud gaming alleviates some of the hardware constraints associated with end user devices, it does come at a cost - an array of performance issues such as increased...
