Research on distributed storage and security protection of mass data the Chao Songnan of Shandong University This paper, based on the research of the security strategy of distributed data and information storage, designs a kind of storage model and query mechanism for the distributed platform, which is suitable for the large data (data). At the same time can provide data sharing integrity check function. Firstly, based on the architecture and principle of the open source Hadoop distributed Data File System (HDFS) and the symmetric encryption algorithm and public key cryptosystem, this paper presents a HDFS distributed data security storage model. The model picks ...

&http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; This chapter describes the open source storage System MFS Linux, which was developed by Poles. The MFS file system enables RAID functionality, not only to save storage costs, but also to professional storage systems and, more importantly, to achieve online scaling. The reader must understand that MFS is a semi distributed ...

Research and optimization of distributed file system based on cloud storage University-ocean in this paper, based on the systematic and comprehensive study and summary of the development status and characteristics of distributed storage system, the advantages and disadvantages of several common distributed storage System architectures are analyzed emphatically. At the same time, a namenode system architecture with partial equivalence is designed. By adding some equivalent multiple namenode in the metadata server layer, the architecture changes the single point dependence of the centralized storage system represented by HDFS, which reduces the latency of concurrent users and the level of metadata server.

Traffic flow data real-time storage system based on HBase Lu Ting Fang Jun Choyank traffic flow data is characterized by multiple sources, high speed and large volume, and traditional data storage methods and systems expose the problems of weak scalability and low real-time storage. In response to the above problems, A real-time storage system based on HBase traffic flow data is designed and implemented. This system uses the distributed storage architecture, through the front-end preprocessing operation to standardize the data, use the multi-source buffer structure to classify the different types of stream data, and combine the consistent hashing algorithm, multithreading technology, and key line optimization design ...

Research on the storage strategy of small text corpus on Hadoop platform normal Zheng Lijie in order to solve the contradiction between the distributed storage and retrieval speed of the small text corpus in the Hadoop platform storage, this paper proposes a new HSCs (Hadoop smalltexts Corpus Storage) Storage policy. The strategy first uses small text merging technology to add a layer of merge_client to the HDFS architecture, merging multiple small text files into a large text file with directory structure, effectively reducing ...

A wide-area video surveillance integrated service platform based on cloud computing Han Haiwen Zider Fengbin A video surveillance integrated service platform based on SOA architecture and cloud computing technology is designed to solve various problems encountered by current wide-area video surveillance projects. Using the virtualization technology in cloud computing to integrate and manage various heterogeneous hardware and software resources in the bottom layer of the platform, using HDFs Distributed File system and HBase distributed storage system to efficiently distributed storage management of massive video data, Using MapReduce distributed programming framework to realize the distributed parallel processing and financing of user's service.

Based on HBase agricultural Wireless sensor information Storage System Zhou Lijian, Chen Qingqui Wireless sensor network due to the spread of the cross-regional, with the expansion of wireless sensor network, how to efficiently organize storage of these cross-regional large-scale sensor data is a hot and difficult problem in recent years. According to the large size and wide distribution of large scale sensors, a distributed storage scheme is designed using hierarchical distribution. The hbase of Hadoop is a distributed database that provides real-time read-write, accessible, highly scalable, and high-availability storage services. Build with HBase ...

What is Dynamo? He is a distributed storage engine for Amazon. 　　So what is this engine? First, suppose a scenario where your site wants to store the IP that the user logs on to. How to solve this problem? The traditional method is to use the database. 　　The database provides the convenient operation interface, the complex query ability as well as the thing guarantee. OK, now suppose everyone loves your site, and more people are visiting. A database has not been processed. So you installed 3 database host, the user divided into three categories (male ...)

In recent days, news of Chinese hackers attacking American companies and the media has been widely publicized, and the Chinese government and military have denied it, saying China is the main victim of cyber attacks. The fermentation of the matter, so that people's eyes quickly focused on the network information security above. With the rapid development of computer technology, information network has become an important guarantee of social development. There are a lot of sensitive information, even state secrets, placed on the network, its security has attracted much attention. 2011, the domestic well-known programmers web site Csdn was hacked, 600多万个 registered mailbox was forced to bare Ben; 2.
