Latest Patents
Yi Ru's latest patents focus on fine-grained access control for data manipulation language (DML) operations on relational data. These embodiments allow for the granting of data change operation-specific privileges to particular users, which can be applied within specific data realms in a given table. Furthermore, User Privilege column-level privileges are explicitly associated with one or more data access operations. This means that the grant of such a column-level privilege allows the user to perform only those data access operations that are explicitly linked to the privilege. The enforcement of these data security policies includes measures to prevent data leakage via WHERE and RETURNING INTO clauses. A two-phase rewrite is utilized to optimize the enforcement of column-level privileges, ensuring that unnecessary privilege checks are avoided based on the columns accessed in a query.
