Precision agriculture relies on real-time data gathering and analysis to maximize yield, minimize environmental impact and reduce cost, which has been envisioned as a new paradigm to revolutionize modern agriculture. However, the collection of farming data, especially geospatial data, raises concerns about potential privacy leakage. In this paper, we propose a novel scalable and private continual...
The purpose of this paper is to show a practical case and what we have learned from carrying on and improving the blended learning strategies continuously in the college teaching. The methods adopted classroom observation and interview in order to collect the student's performance and problems. The authors employ an action research method to analyze those problems, and use ICT to improve the blended...
Remote user authentications are an essential tool for e-commerce in Internet environment. In these systems, identity privacy is provided by concealing user's identity. In this article, we introduce the identity privacy study of this setting, and explore a secure and efficient dynamic ID-based remote user authentication protocol with untraceability. We adapt a pair of dynamic IDs to realize the user's...
The major industrial accidents have occurred from time to time, which has a serious threat to people's property and lives. This paper builds a major hazard management system based on 3DGIS, does some research about the system structure and the key technology, and analyzes and designs the main system's functions and database. The system displays and manages a variety of basic information and data of...
We apply a kind of data origin authentication algorithm that is robust against data packet loss and injection to the video multicast communication. In this algorithm, we combine the efficient packet-injection resistant multicast source authentication protocol (EPJRSA) with the Signature Amortization using Rabin's Information Dispersal Algorithm (SAIDA) to make sure that both the data and the authentication...
Conventional data grid systems require the application to access remote data through explicit APIs, consequently sacrificing user transparency. Thus, some systems enable the application to transparently access remote data by copying the entire file to a userpsilas local storage before executing the application, even when only a tiny file fragment is required. Such an approach consumes unnecessary...
Federated systems have recently attracted much attention because they allow loosely coupled organizations to share resources for common benefits. However, discovering resources across administrative boundaries is challenging. Despite their willingness to share resources, many organizations prefer not to export their internal resource description to unfamiliar parties. While it is highly desirable...
