Confidentiality of data is maintained, and the ability of storage systems to perform data reduction functions is supported. Encrypted data to be written to a storage system is separated into one or more data chunks. For a data chunk, a master encryption key for an owning entity associated with the data chunk is retrieved. The data chunk is decrypted into plaintext, and the plaintext is transformed by performing one or more advanced data functions. A private key is created and used to encrypt the transformed plaintext, which is stored as a first encryption unit. A wrapped key is created by encrypting the private key with the master key, and is stored as metadata for the encryption unit to limit data access to the owning entity."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Shared data encryption and confidentiality","description":"Embodiments relate to deduplication and compression on data performed downstream from where the data is encrypted.
