The disclosure generally relates to a system and method for randomly generating unlock codes and identifiers for locks, and creating unlock code and identifier pairs. In an exemplary embodiment, the invention is integrated with, or part of, a distributed management system that controls access to various locations, such as, for example, self-storage units, hotel rooms, apartment buildings, storage containers, short-term housing rentals, lockers, equipment rooms, vaults, hospitals, airports, government facilities, nuclear power facilities, water treatment facilities, weapon storage facilities, aircraft cockpits, and any other setting that requires restricted, selective, or monitored access that can be remotely controlled, whereby users can receive unlock codes electronically on their mobile device.

An access arrangement for a vehicle includes a vehicle-side transceiver for transmitting query signals in a chronologically successive manner in first specified time intervals. The access arrangement also includes at least one mobile identification transmitter including an identification transmitter-side transceiver with an adjustable reception sensitivity for receiving the query signals of the vehicle-side transceiver. Furthermore, the access arrangement includes a monitoring device for outputting a control command in order to reduce the sensitivity of the identification transmitter-side transceiver by a first specified amount if the identification transmitter-side transceiver has received a specified number of query signals transmitted by the vehicle-side transceiver. By reducing the reception sensitivity, a stationary identification transmitter in the vicinity of the vehicle for example remains operational but no longer reacts to query signals of the vehicle-side transceiver, whereby power can be saved.

A smart key system includes: a plurality of mobile devices each of which can be carried by a user, and is assigned unique identification information; and a control unit that is provided in an opening/closing body, performs an inquiry to the plurality of mobile devices by radio wave transmission, and locks or unlocks the opening/closing body when verification of the identification information responded from any of the mobile devices succeeds. The control unit performs simple verification for confirming presence or absence of the plurality of mobile devices within a response area, before verifying the identification information, and performs formal verification of the identification information for a mobile device that has been confirmed to be present by the simple verification, among the plurality of mobile devices.

A door handle including light emitters for emitting light out of the handle, light detectors, lenses oriented relative to the emitters and detectors such that for each emitter-detector pair, when a reflective object is located at a target position near the handle, corresponding to that emitter-detector pair, then the light emitted by that emitter passes through one of the lenses and is reflected by the object back through one of the lenses to that detector, a keyless lock that, when activated, scans for a digital key via wireless communication, and a processor operable to synchronously activate emitter-detector pairs, to recognize from the amounts of light received by the activated detectors, and from the target positions corresponding to the activated emitter-detector pairs, that the object is approaching the handle and performing a sweep gesture and, in response thereto, to activate the keyless lock.

Disclosed are methods, systems, and computer-readable media for wireless key management for authentication. Authentication includes transmitting a request to a locking device, transmitting a security challenge to the mobile device, and transmitting a response to the challenge and an encrypted user profile for the locking device. The response includes data generated with an access key that is stored by both the mobile device and the locking device, and the user profile is encrypted by a server using a secret key that is stored by the server and the locking device. Authentication further includes verifying the response to the challenge, where the response is verified using the access key, and validating additional data from the mobile device. An action of the locking device may be initiated as specified by the request.

A method of operating an electrical control unit of a smart key system includes receiving a first GPS coordinate that is transmitted from a smart key, calculating a distance from the smart key based on the first GPS coordinate and a second GPS coordinate of a vehicle that is received from a GPS satellite, determining whether the distance is within a predetermined reference distance, transmitting a first communication request signal to the smart key when the distance is within the reference distance, determining whether a first communication response signal corresponding to the first communication request signal is received from the smart key, performing the first communication with the smart key when the first communication response signal is received, and controlling the vehicle in accordance with a control signal transmitted from the smart key based on the first communication.

An access control system and a method for operating an access control system are provided. The access control system includes an access control device. The method provides a step for initiating the transmission of the advertising signal by a communication module of the access control device, the advertising signal being received by a mobile device. The method provides a step for automatically receiving an access credential from the mobile device to the communication module of the access control device. The method provides a step for comparing, in an authentication module, the access credential with an authorized access credential (e.g., stored in a memory of the access control device).

To control access to a predetermined service or area, a system receives an activation signal indicative of a user's activation of an access code. As a result of receiving the activation signal, the system sends a verification code to a portable electronic device of the user. An access terminal receives the verification code. Access to the predetermined service or area is granted if the verification code is received at the access terminal meeting one of several predetermined conditions. One condition requires that the verification code is provided to the access terminal within a limited validity time.

A system that allows a user to access a secured area by confirming location of the user near the secured area and receipt of an access word by the system. A user in possession of a mobile device may be detected at the entrance to a secured location. The system can select a question asking for a passcode corresponding to certain access to the secured location. The question can be spoken to a user through a loudspeaker at the secured location. The user's spoken response can be processed by the system, for example using keyword spotting, to determine if the proper access word is included. If it is, the system can grant access to the secured area.

The present disclosure provides an apparatus, method and system for use with a vehicle having passive keyless entry and start (PKES) system including a vehicle unit and a key fob storage unit. The vehicle united is to be installed with the vehicle having a first transceiver, a first relay transceiver an authentication unit, a first controller for controlling said first relay transceiver allowing said transmission if said user is authenticated. The key fob storage unit comprises at least one housing for securely holding at least one key fob associated with said PKES systems of said vehicles, a second, said second wireless relay w wherein said first relay transceiver and said second relay transceiver allows said PKES system and said key fob to communicate from a distance larger than a range of said PKES system signals.
