  • Publication number: 20200387627
    Abstract: A database system (1) and method (100) comprising a database system memory (3) and at least a first database server (9). The database system memory (3) stores a database of data records (7) and shared program instructions (51) between first and second database users (21, 31). The shared program instructions (51) define a privacy model (13) comprising privacy restrictions (14, 23, 33) for the first and second database users (21, 31), respectively, and specify an authorization model (19) comprising a first set of authorizations (25?, 35?) that permit the first database user (21) to manipulate a first subset (27) of the data records consistent with the first user's privacy restrictions (23?, 33?) and a second set of authorizations (25?, 35?) that permit the second user (31) to manipulate a second subset (37) of the data records consistent with the second user's privacy restrictions (23?, 33?).

  • Publication number: 20190295182
    Abstract: A computer system (100) comprising: a global synchronization log (112) that stores public data associated with private data wherein the private data is stored in one or more private data stores (132, 134) separate from the global synchronization log (112, 114); and one or more nodes (102) operable in a mode as a writer node (102) that has access to write the public data associated with private data to the global synchronization log (112). A reader node (120) may verify the public data on the global synchronization log (112, 114) with private data stored in one or more private data stores (132, 134).
