Research on the model of big data serve security in cloud environment

摘要

A model of big data security service is put forward for large data providers, users and cloud service providers, in order to achieve shared services of reliable data security. Security of technology framework is established from four levels including a large resource set for searching, matching and packaging data, large data resources decomposition modeling planning, trust evaluation and optimization, and big data algorithm, on the aspect of access security mechanism, data security, network transmission security and cloud storage security to protect large data.
