Abstract
Embodiments relate to operating a data processing system. An aspect includes receiving a request for data storage by an application server, said request comprising restricted-access data. Another aspect includes processing the request in the first application server thereby extracting said restricted-access data from the request. Another aspect includes encrypting said restricted-access data with a cryptographic key associated with said privacy regime to a cipher representation. Another aspect includes defining a masking rule relative to the field designated for storage of the cipher representation, the masking rule defining a set of privacy regimes applicable to processing of the restricted-access data. Another aspect includes forwarding the cipher representation and the masking rule to the shared database by a database client. Another aspect includes maintaining information about the cryptographic key in said database client for allowing plaintext reconstruction of restricted-access data from the cipher representation when retrieved from the shared database.
