In view of the present family security coefficient and poor family environment information control were complicated, family members can't access to environmental information conveniently, this paper proposed a Raspberry Pi as nuclear core processor used in the Internet of things of the family embedded robotic system, by used the 802.11 g and TCP/IP, HTTP to realize the infinite distance signal transmission,...
Information safety is significant for state security, especially for intelligence service. OSIA (open source intelligence analyzing) system based on cloud computing and domestic platform is designed and implemented in this paper. For the sake of the security and utility of OSIA, all of the middleware and involved OS are compatible with domestic software. OSIA system concentrates on analyzing open...
IP Multicast benefits data center networks (DCNs) for saving bandwidth and improving throughput. In-packet Bloom filter (BF) has been recently proposed to achieve efficient and scalable multicast in DCNs, where a Bloom filter encodes all nodes in a multicast tree into the packet header for making routing decisions. However, prior work incurs large traffic overhead due to tree encoding and false positive...
National meteorological communication system is the main project in CMA. For improving system credibility,the system uses the load balance technology to build cluster system. The communication servers make use of cluster technology to ensure that all of the servers in the cluster system can share the storage. In this article, cluster and cluster file system are introduced. Future more, the architecture...
Location-based services (LBS) have become an immensely valuable source of real-time information and guidance. Nonetheless, the potential abuse of users' sensitive personal data by an LBS server is evolving into a serious concern. Privacy concerns in LBS exist on two fronts: location privacy and query privacy. In this paper we investigate issues related to query privacy. In particular, we aim to prevent...
The paper proposes a new test model, Call-For-Testing (CFT), and applies it to User Acceptance Testing (UAT) of Web Applications. Different from traditional approaches, UAT in the context of CFT only means beta-testing on the site or field, i.e., by customers or end-users, and does not include alpha-testing which is supervised or performed by the system provider. CFT model leverages open community...
We address issues related to privacy protection in location-based services (LBS). Most existing research in this field either requires a trusted third-party (anonymizer) or uses oblivious protocols that are computationally and communicationally expensive. Our design of privacy-preserving techniques is principled on not requiring a trusted third-party while being highly efficient in terms of time and...
