Fine-grained cloud storage data integrity detection method in cloud storage service, a fine-grained cloud storage data integrity detection method is proposed in order to enable users to know the integrity of the data on the cloud server conveniently and quickly. The file is divided into a file block and then divided into a basic block, through the introduction of bilinear pairs and users randomly selected to detect the data block can detect the integrity of the data indefinitely, in addition, through the introduction of trusted third party to solve cloud user and cloud vendor disputes, to achieve the public verification of cloud storage data. Then the correctness and safety analysis of the proposed method are given, and the experiment proves that ...

Dynamic service for large-scale data processing private cloud system Wang Zhu, Merlin, Lilei, Chang, Hu Guang Summary: In order to adapt to a private cloud environment with large amount of data, computationally intensive, complex process of computing task demand, for reference to the public cloud computing related theory and technology, combining the characteristics of private cloud environment, This paper presents an implementation scheme of a dynamic service private cloud system which adapts to large-scale data processing. This scheme uses the job file to describe the computing task, constructs the processing work flow dynamically with the job logic structure, and introduces the MapReduce parallel framework through the data stream driver service request.

Research on distributed data stream clustering algorithm based on Hadoop mapreduce Cai Binlei Ningjiadong Zhu Shiwei Guo Qin with the continuous increase of data flow scale, the existing clustering algorithm based on grid has no effect on the clustering of data streams, can not find any shape clusters in real time, and can not delete the noise points in the data stream in time. This paper presents a distributed data stream clustering algorithm (Pgdc-stream) based on grid density in Hadoop platform environment, which facilitates the parallel clustering of data flow in MapReduce framework based on Hadoop.

A large data processing algorithm for energy efficiency in heterogeneous clusters Ding, Qin Xiaolin, Liuliang, Wang Tao Spring cluster energy consumption has exceeded its own hardware acquisition costs, and large data processing needs large-scale cluster time-consuming, so how to carry out high energy efficient data processing is a problem for both the owner and the user. is also a huge challenge to energy and the environment. Existing research is generally done by shutting down some nodes to reduce energy consumption, or by designing new data storage strategies to implement energy efficient data processing. Through analysis, it is found that even the least-used nodes exist ...

More and more companies, individuals have the importance of the data, more than ever before momentum. The concept of big data is everywhere, as if everyone is talking about big data, met without greetings of big data, as if it was not in the data world.

At ordinary times, whether the user research, product operation or competitive analysis, the analysis of the data, if there are some differences in the project who can not convince who, many times is also to take data to speak, visible in the development of products, statistics and analysis of the data is very important. Everyone said that the data is objective, but in fact, the data by the background environment, statisticians, statistical methods, analysts, such as the impact of multiple factors, so that we are in statistics and analysis often fall into the wrong, not the right answer. Let's say a few two common misconceptions about data. Misunderstanding one ...

From ancient to ancient times, people are always in the record, are in storage. 　　 　　From ancient stone carvings, bamboo slips, to cloth, paper, to compact discs and flash memory, storage has been becoming simpler and more massive. In the field of computers and Internet, storage has changed dramatically in just ten years. From small-capacity floppy disks to oversized removable hard disks, from portable high-capacity discs to smaller USB drives, from solid media to network-based cloud storage. 　　 　　Regardless of capacity, media or use, personal storage has a qualitative upgrade. In the past, we have saved data to ...

In the analysis of website data, time is one of the most common and indispensable dimensions, most of which are used to limit the range and granularity of index statistics, while time factors can also affect some statistical rules and details of indicators, and in some data analysis it is easy to overlook the effects of time factors, 　　These effects may mislead the final conclusion. Found that the problem is in a data extraction requirements, the site will release a lot of new content every day, these new content needs to be recommended, otherwise it will be buried, so many sites will have "the latest recommendations" and other modules ...
