A Novel Approach for Improving Security and Storage Efficiency on HDFS

Distributed file system for the storage of massive files have obvious advantages compared with the conventional file system. For instance, Hadoop Distributed File System (HDFS) implemented with commodity hardware has the advantages of low cost, high fault tolerance, scalability, etc. However, HDFS has the potential safety hazard due to the unencrypted data stored in Datanode, which may cause da...

a benchmarking approach to optimal asset allocation for insurers and pension funds

uncertainty in the financial market will be driven by underlying brownian motions, while the assets are assumed to be general stochastic processes adapted to the filtration of the brownian motions. the goal of this study is to calculate the accumulated wealth in order to optimize the expected terminal value using a suitable utility function. this thesis introduced the lim-wong’s benchmark fun...

Research and implementation on cloud computing security based on HDFS

This paper focuses on the research of the cloud computing security, proposing the file data management model and implementing the security of the cloud computing based on HDFS. The design of the file data management system under the cloud computer environment is achieved based on HDFS, which is with the functions of upload and download data parallelism, user management, inventory management, et...
