An aging population has inspired the marketing of advanced real-time ambient assisted living solutions. However, the accurate collection of behavior information, recognition of human activities and implementation of this scheme in a real living environment is a challenging task. In this paper, we propose a feasible extended framework which is compatible with common devices and protocols. Specifically,...
Online education is a popular way for distance education in the world. The data of online education platform is explosively growing. The Big Data technologies can process and analyze the massive data and facilitate the user experience and teaching quality. This paper proposes an online education Big Data platform that aims at improving the quality of education by analyzing a large amount of data generated...
It is a challenging problem to securely resist the collusion of cloud server and query users while implementing nearest neighbor query over encrypted data in cloud. Recently, CloudBI-II is put forward to support nearest neighbor query on encrypted cloud data, and declared to be secure while cloud server colludes with some untrusted query users. In this paper, we propose an efficient attack method...
In this paper, we propose a new efficient solution for securely outsourcing linear regression to a public cloud with robust answer verification. Additionally, we show our construction can be utilized to efficiently and securely outsource other large-scale matrix operations, such as determinant computation.
Public cultural services are developed rapidly. The growth of the data related to the public cultural services are dramatically. It needs big data technologies for processing the massive public cultural data. This paper proposes a big data analysis platform for facilitating the public cultural services. The platform collects cultural data from public cultural institutions and analyzes the data by...
Chinese Characters are important elements of Chinese culture. Digitization techniques of Chinese Characters introduce attractive experiences of Chinese Character culture. The Chinese Character digitization generates large-scale data that is hard handled by traditional methods. To address this issue, in this paper, we propose Chinese Character Culture Big Data Platform that is designed based on the...
In the era of Internet, service-oriented development becomes a popular software development paradigm for developing large-scale systems and cloud apps. Followed by this new emerging paradigm, functions would be designed and developed as components, deployed separately and provided as services for integration. In generally, experienced developers tend to introduce some reusable distributed service...
The big data collection and analysis of public digital culture sharing service is researched in this paper. Big data includes three types of data, namely: ancillary service data, public digital culture sharing service platform operation data and user data. The aim is to build a data analysis platform for the three classes of data. Through the analysis of the three types of data collected, the use...
Big data processing is one of the hot scientific issues in the current social development. MapReduce is an important foundation for big data processing. In this paper, we propose a semantic++ MapReduce. This study includes four parts. (1) Semantic++ extraction and management for big data. We will do research about the automatically extracting, labeling and management methods for big data's semantic++...
As an important resource and productive element, big data permeates all the domains, such as: E-commerce, traffic management or smart city. When possessing the capability of aggregating the information and then mining and analyzing deeply the latent knowledge, it will bring endless innovative achievements. Therefore, big data mining and deep analytics is becoming one of the research hotspots, and...
As one of the fundamental technologies in cloud computing, services computing is playing a critical role to enable provisioning of software as a service (SaaS). However, how to effectively and efficiently develop and deploy personalized SaaS and enterprise mashups on the cloud platforms remain a big research challenge. SaaS developers and researchers may adopt certain strategies by leveraging existing...
Along with the growing attention, cloud computing is not only changing the computing paradigm, but also the style of computing in which dynamically scalable and virtualized resources are provided as services over the Internet. Cloud computing introduces a lot of chances, as well as, challenges in the new trend. Taiwan has been well known as a major Information Communication Technology (ICT) manufacturing...
To move applications to the cloud is not only a technical decision but also a business-oriented decision, in which both business and technical factors (e.g. transformation effort, multi-tenancy and auto-scaling enablement, scalability and extensibility) should be considered. However, existing approaches and tools do not support a consumable business oriented cloud transformation decision to select...
Cloud computing has been attracting much attention since its birth. How to cloudify software systems especially legacy applications in the cloud era is becoming increasingly important. Based on RGPS meta-model framework and International standards-ISO/IEC 19763, an architecture for cloudification of legacy applications is proposed, which consists of three parts: a Web portal, a SaaS service supermarket,...
When our private data are out-sourced in cloud computing, we should guarantee the confidentiality and search ability of the private data. However, nowadays privacy preserving issues in the cloud have not been carefully explored at current stage. To relieve individuals' concerns of their data privacy, this paper explores a new approach based on private matching and min-attribute generalization to solve...
In view of the disadvantages of traditional measurement and control system, this article has proposed a cloud computing based on IEEE1451. It has defined the functions and goal of this system through the analysis of market demands, set up a hierarchical structure model, and established a software structure and application pattern with the combination of C/S structure and B/S structure.
People can only enjoy the full benefits of Cloud computing if we can address the very real privacy and security concerns that come along with storing sensitive personal information in databases and software scattered around the Internet. There are many service provider in the internet, we can call each service as a cloud, each cloud service will exchange data with other cloud, so when the data is...
