Data Entity Security Metadata for Consistent Access Control

The patent introduces data entities as intermediary objects between applications and the database. These data entities contain embedded security metadata that acts as a mediator, translating application access requests into consistent security decisions. The data entity serves as the intermediary that ensures all applications adhere to the same security rules defined in the metadata, thereby maintaining security consistency while allowing application-level customization.

The patent moves security controls from the application layer to the data layer by embedding security metadata within data entities. This dimensional shift from application-centric security to data-centric security creates a new layer of abstraction where security policies are defined independently of applications. The security metadata in the data entity provides authorization information that transcends individual application contexts, ensuring consistent enforcement across all applications.

The patent segments security controls into discrete security metadata attributes embedded within each data entity. Each data entity carries its own security metadata containing authorization information, creating granular, fine-grained security segments. This segmentation allows individual data elements to have specific security requirements independent of the application or user accessing them, thereby maintaining security integrity as the system scales to support more applications and users.

The data entities provide self-service security enforcement by containing embedded security metadata that automatically guides access decisions. The security metadata within each data entity enables the system to autonomously determine authorization without requiring complex external security checks for each access request. This self-service mechanism reduces security risks by ensuring consistent security enforcement regardless of the number of applications or users accessing the data.

The patent merges security metadata directly into the data entity structure, combining data and security information into a single unified object. This merging eliminates the need for separate security management systems and simplifies the overall architecture by integrating security controls within the data representation itself. The consolidated data entity with embedded security metadata reduces transformation complexity compared to maintaining separate security layers.

The data entity serves multiple functions simultaneously: it stores data values, contains security metadata for authorization, and enables consistent security enforcement across all applications. This multi-functionality reduces the need for separate security infrastructure and simplifies the system by having a single object type handle both data storage and security enforcement, thereby reducing overall transformation complexity despite the added security capabilities.
