Differential Access Control via Multi-Secret Authentication

The patent segments authentication secrets into multiple components (first secret, second secret, third secret) where each secret provides a different level of access. Instead of relying on a single secret, the system divides authentication into hierarchical levels, so that compromise of one secret does not grant complete system access. This resolves the contradiction by maintaining ease of operation through simple secret entry while improving security through segmented access control.

The patent applies local quality by assigning different security properties to different authentication secrets. The first secret provides basic access, the second secret provides elevated access, and the third secret provides administrative access. Each secret has localized security characteristics appropriate to its access level, allowing the system to maintain ease of operation while achieving reliable security through differentiated secret properties.

The patent applies universality by designing a single authentication interface that handles multiple secret types and access levels. The same user interface and processing logic accommodate first secrets, second secrets, and third secrets without requiring separate authentication systems. This resolves the contradiction by achieving reliable segmented security while maintaining relatively simple device complexity through a universal authentication mechanism.

The patent implements dynamics by allowing the system to adaptively select which secret validation logic to apply based on the authentication context. The system dynamically adjusts between different secret verification processes (first secret validation, second secret validation, third secret validation) depending on the access request, enabling flexible multi-level security without permanently complexifying the authentication structure.

The patent segments information access rights corresponding to different secret levels. Users authenticated with a first secret access only basic information, while users authenticated with a second or third secret access progressively more sensitive information. This segmentation ensures that if a first secret is exposed, attackers cannot access the segmented protected information requiring higher-level secrets, thus reducing information loss while maintaining convenient access for authorized users.

The patent applies preliminary anti-action by pre-restricting access to sensitive information before any authentication occurs. The system is configured in advance so that even if a secret is compromised, the segmented access control structure already in place prevents automatic access to all information. This preliminary protective structure reduces potential information loss while maintaining ease of operation for legitimate users with appropriate secret levels.
