Distributed computation method and system based on mapreduce of large amount data

摘要

PURPOSE: A map-reduce based large data distribution calculating method and a system thereof are provided to secure end-to-end confidentiality by using statistical data through HE(Homomorphic Encryption) operation. CONSTITUTION: A security agent(120) receives data from a data provider(110) and encodes data according to an encoding type. The security agent generates a computing program for operating the encoded data. The security agent stores the data in an HDFS and generates blocks. The security agent extracts a pair of keys/values by analyzing the blocks.
