US 2026/0074904 A1 · SYSTEMS AND METHODS FOR ACCESS TO ACCESS-CONTROLLED RESOURCES USING DIGITAL KEYS

Abstract

Systems and methods control access across access systems. A reader receives a token from a user authenticator, and permission is determined by validating the token. When permitted, a digital key bound to a target resource is generated. A receiver of an access system obtains and verifies the digital key—optionally offline—and actuates the access system to perform an authorized operation. The token may include a first identifier portion usable by a first access system and an appended extension portion encoding data usable by one or more additional access systems. Extensions may be written or removed via a server-supplied amendment package or a locally unlocked package on a device or a first or third-party application, thereby augmenting or revoking privileges while preserving usability of the token by the first access system. The approach applies to locks, enclosures, compartments, devices, vehicles, and other access-controlled resources.

Claims21

Dependent claims

A system for amending one or more authorization states of a user authenticator, the system comprising:

a user authenticator that provides a user with first access rights to a first resource, access to the first resource being limited by a first access system;
and
a device comprising one or more processors and memory storing instructions that, when executed by the one or more processors, cause the device to:
(i) receive data indicative of a user's altered access rights with respect to a second resource, access to the second resource being limited by a second access system distinct from the first access system;
and
(ii) write the data to the user authenticator, or cause the data to be written to the user authenticator, to provide the user authenticator with the altered access rights with respect to the second resource;
wherein the user authenticator is configured to store the data;
wherein, upon presentation of the user authenticator to the second access system, the user authenticator provides the user access rights to the second resource in accordance with the altered access rights;
and
wherein, after the writing of the data to the user authenticator, the user authenticator continues to provide the user with the first access rights to the first resource.
