Local Host Interface for Dual Endpoint Cloud Access Control

The patent introduces a local host interface as an intermediary between the end-user entity and the remote cloud server. This interface mediates all access requests by first evaluating local access policies before forwarding to the cloud server, which evaluates remote access policies. This intermediary layer simplifies the overall system by distributing policy evaluation across multiple locations, making each individual policy easier to manage and less prone to misconfiguration while maintaining strong security.

The patent segments the access control system into two distinct parts: a local host interface that handles local access policies and data privacy, and a remote cloud server that handles remote access policies. This segmentation allows each component to operate independently with its own policy evaluation logic, enabling centralized security management while preserving local data privacy and control. The local interface retains information about local access decisions, preventing loss of privacy-sensitive data.

The patent creates a universal access control framework where the local host interface serves multiple functions: it evaluates local access policies, encrypts data locally, and forwards requests to various cloud servers. This universal interface can work with different cloud service providers (AWS, Azure, Google Cloud, etc.) while maintaining consistent security practices. The standardized local interface ensures uniform access control behavior across different cloud providers, resolving the inconsistency problem while preserving service versatility.
