PRIVACY PRESERVATION IN DIGITAL ECONOMY PLATFORMS

As we know, we are living in the era of the digital economy, which relies on electronic computing. In any technological or digital economy field, privacy preservation is our major concern. Every device that can process, store, or communicate needs privacy. The privacy preservation field is polished by many researchers based on cloud computing and big data. New research on privacy preservation based on cloud computing, big data and other platforms creates innovation in this field. This paper proposes existing different techniques which are helpful in the field of privacy preservation and trying to explore the field from numerous aspects. We are making a comparison of different techniques and analysing it deeply with the multiple types of constraints which relate to privacy. It includes the combined ideas of different authors about their work carried out from the different types of platforms. This paper also addresses the security threats and how to overcome these privacy threats. Future or emerging trends about privacy preservation against big data and cloud computing are discussed.
