Abstract: Row-level security (RLS) may provide fine-grained access control based on flexible, user-defined access policies to databases, tables, objects, and other data structures. A RLS policy may be an entity or object that defines rules for row access. A RLS policy may be decoupled or independent from any specific table. This allows more robust and flexible control. A RLS policy may then be attached to one or more tables. The RLS policy may include a Boolean-valued expression.

Abstract: A shared database platform implements dynamic masking on data shared between users where specific data is masked, transformed, or otherwise modified based on preconfigured functions that are associated with user roles. The shared database platform can implement the masking at runtime dynamically in response to users requesting access to a database object that is associated with one or more masking policies.

Abstract: A database system facilitates secure data sharing by implementing projection constraints within a query processing framework. Upon receiving a query directed to a shared dataset, the system, utilizing hardware processors, identifies a subset of data within the dataset that is subject to a projection constraint policy. The applicability of the projection constraint is determined based on the context of the query, which is derived from a data sharing agreement. The system processes the query by selectively restricting the projection of data values from constrained columns, while allowing specific operations to be performed on the data. The output generated in response to the query is compliant with the projection constraint policy, providing derived data based on the allowed operations without revealing the actual data values. This ensures the confidentiality of sensitive information while enabling collaborative data analysis and sharing among various users of the database system.

Abstract: Aspects of the present disclosure address systems, methods, and devices for tracking object dependencies in a cloud database system. An object dependency created between a referencing object and a referenced object is detected. Based on detecting the object dependency, a dependency record is generated. The dependency record includes dependency information describing the object dependency between the reference object and the referenced object. The dependency record is stored in a database of dependency records.

Abstract: Embodiments of the present disclosure may provide a streamlined process for performing operations, such as data sharing and data replication, using multiple accounts. A global identity (also referred to as an organization user) may be employed, where the global identity may have access to multiple accounts across the same or different deployments. The global identity may switch between accounts from its login session and perform various tasks in the context of different accounts without undergoing further authentication.

Abstract: A noisy aggregation constraint system receives a query for a shared dataset, where the query identifies an operation. The noisy aggregation constraint system accesses a set of data from the shared dataset to perform the operation, the set of data comprises data accessed from a table of the shared dataset. The system determines that an aggregation constraint policy is attached to the table, the policy restricts output of data values stored in the table. Based on the context of the query, the system determines that the aggregation constraint policy should be enforced in relation to the query. The system assigns a specified noise level to the shared dataset and generates an output based on the set of data and the operation; the output comprises data values added to the table based on the specified noise level.
