Security Challenges Associated with High Dimensional Data

Big data implies performing computation and database operations for massive amounts of data, remotely from the data owner’s enterprise. Since a key value proposition of big data is access to data from multiple and diverse domains, security and privacy will play a very important role in big data research and technology. The variety, velocity and volume of big data amplifies security management challenges that are addressed in traditional security management. Big data repositories will likely include information deposited by various sources across the enterprise. This variety of data makes secure access management a challenge. Each data source will likely have its own access restrictions and security policies, making it difficult to balance appropriate security for all data sources with the need to aggregate and extract meaning from the data.
