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.
