WLAN Hotspot Dynamic Password Update for Unauthorized Access Prevention

The patent transforms the static access password into a dynamic one that automatically changes over time. The system implements periodic password updates based on preset time intervals, making the password a moving target that unauthorized users cannot exploit indefinitely. This dynamic approach resolves the contradiction by maintaining security through automatic changes while requiring minimal user intervention.

The patent applies periodic action by implementing automatic password updates at predetermined time intervals. The system schedules password changes periodically without requiring manual user input, thus maintaining security through regular updates while preserving ease of operation. This periodic mechanism ensures that even if passwords are compromised, the window for unauthorized access is limited.

The patent implements preliminary action by pre-setting authentication credentials (passwords, tokens, or certificates) that are valid only for specific time periods or data quotas. Before unauthorized unlimited consumption can occur, the system has already established expiration times or traffic limits on each authentication credential, preventing excessive data loss while maintaining continuous authorized access.

The patent employs feedback mechanisms by continuously monitoring data traffic consumption and authentication status. When unauthorized users attempt to consume data or when traffic limits are approached, the system provides feedback through authentication failures, warnings, or automatic disconnections. This real-time feedback loop prevents unlimited data consumption while keeping the hotspot accessible to authorized users.

The patent implements self-service by enabling the WLAN hotspot system to automatically update its own access passwords without requiring user intervention. The system autonomously generates new passwords, manages authentication credentials, and updates security parameters based on predefined policies and time intervals. This self-service capability maintains high security while eliminating the operational burden on users.

The patent replaces the mechanical manual password update process with an automated electronic system. Instead of requiring users to manually change passwords through interface interactions, the system uses automated algorithms, timers, and authentication protocols to update credentials electronically. This substitution maintains security rigor while dramatically improving operational convenience.
