Endpoint File Export Security via User Permission Segmentation

The patent segments user permissions into distinct categories: read access, write access, and export access. Users can be granted specific permissions based on their role and needs. For example, a user can have read access to view files but not write or export them, while another user can have write access to modify files but restricted export capabilities. This segmentation allows the system to maintain data security while providing appropriate access levels to different users.

The patent implements local quality by applying different permission levels to different users, files, and operations. Instead of a uniform access policy, the system allows administrators to configure granular permissions where specific users can access specific files with specific operations enabled or disabled. This enables tailored access control where each user experiences the appropriate level of access based on their individual requirements, balancing security with operational needs.

The patent implements a universal permission control system that manages multiple types of permissions (read, write, export) across multiple files and users through a single integrated framework. The permission management module serves multiple functions: it authenticates users, determines their permission levels, enforces access controls, and logs permission violations. This multi-functional approach consolidates what could be separate complex systems into a unified permission management architecture, reducing overall system complexity while maintaining comprehensive security controls.

The patent introduces a permission control module as an intermediary between users and the data storage system. This intermediary layer handles all permission-related operations: it receives user authentication requests, determines appropriate permission levels based on user roles and file characteristics, and enforces access controls before allowing operations. By placing this intermediary between the user and data, the system manages complexity in a centralized location rather than distributing it throughout the entire system, making the permission control mechanism more manageable and maintainable.

The patent implements preliminary action by establishing permission controls and access restrictions before users can access or share files. The system pre-configures permission levels for each user based on their role, the sensitivity of the data, and business requirements. Before a user can access a file, the system checks their permission level and only allows operations they are authorized to perform. This preliminary permission validation prevents unauthorized sharing before it can occur, blocking potential data loss at the point of access rather than detecting it afterward.

The patent implements feedback mechanisms that monitor and track user access and permission violations. The system logs permission checks, access attempts, and any violations of permission policies. This feedback information is used to identify patterns of unauthorized access attempts, track data movement, and alert administrators to potential security issues. The feedback loop allows the system to continuously improve its permission enforcement and prevent information loss by learning from access patterns and violation attempts.
