Due to the Exponential Growth of Unstructured Data In Today's Information World, Big Data
Infrastructure Is Essential For a Wide Range of Applications Across Various Industries. Because of The
Variety of Information Sources and the Volume of Data Involved, Data Ingestion and Retrieval Are
Important Processes During Which User Data Must Be Protected. Accordingly, Authors Proposed a Big
Data Security Architecture Using Split and Merge Security Methods In Big Data. Organizations Conducting
Big Data Initiatives and Data Security Specialists Will Benefit from This Work. and Mainly Study In Which
Discussed About Cloud Security, Cloud Data Security Issues, Cloud Security Requirements, And
Challenges In Storage of Big Data Over Cloud, Cloud Infrastructure, and Security In Cloud Infrastructure,
Data Security, and Security Issues In Cloud Computing.
