Data de-duplication, a vital component of data management and storage optimization, has raised concerns about data security and privacy. In response to these concerns, we present an innovative approach, "Efficient Content Discovery and Preservation for De-duplication (ECDPD)," designed to secure data during the de-duplication process. ECDPD introduces efficient content discovery mechanisms and robust preservation techniques, ensuring that sensitive data remains confidential while realizing the benefits of de-duplication. Our study addresses the pressing need for data security in an era of increasing data proliferation.
