This invention discloses an optimized
access control system for all types of electronic products based on a dual-layer independent
authentication element, belonging to the field of device
security authentication technology. The
system adopts a dual-layer independent architecture: a hardware-fixed first
authentication element and a user-created second
authentication element. The first authentication element is the factory-fixed baseline information of the device, while the second authentication element is generated after the user's first
verification of a custom sub-element. The
system generates an
authorization credential uniquely bound to the current device and application, which cannot be reused across devices or applications. For consecutive authentication failures, the system implements tiered
delay, temporary
blacklisting, and time-limited
blacklisting strategies, only rejecting authentication requests without modifying user data. Users can choose whether to clear historical
authorization credentials when modifying custom sub-elements. Only those with valid first authentication element
verification can access the second authentication data. The system supports
authorization record management and automatic cleanup upon uninstallation. This invention features a simple architecture,
high security, effective prevention of brute-force attacks and theft, strong versatility, and applicability to all types of electronic products.
