It is provided a method for controlling access to a physical space using a co-sign delegation. The method is performed in a lock device and comprises the steps of: receiving an access request from an electronic key; obtaining a plurality of delegations, wherein each delegation is a delegation from a delegator to a delegatee, the plurality of delegations collectively forming a chain of delegations; determining that a delegation is a co-sign delegation, indicating that all further delegations need to be cryptographically signed by both the delegator of the respective delegation and by an access controller; and granting access to the physical space when the chain of delegations start in an owner of the lock device and ends in the electronic key; and when all delegations in the chain of delegations after the co-sign delegation are cryptographically signed by both the delegator of the respective delegation and by the access controller.

A method, apparatus and system for information prompt, and an intelligent electronic door lock are provided. The method includes: when detecting that an intelligent electronic door lock performs an operation for unlocking a door, determining a target user behavior type corresponding to the operation for unlocking the door, obtains target user concern data corresponding to the target user behavior type, and generates to-be-output prompt information based on the target user concern data; wherein, the prompt information is configured for prompting a user to perform a target behavior or displaying the target user concern data, and the target behavior is a behavior corresponding to the target user concern data; and outputting the prompt information. The problem that the intelligent door lock system has a single humanized function may be solved.

A method for operating an access control comprises creating a plurality of wake-up schedules for a wireless transceiver. Each of the plurality of wake-up schedules may be configured to control how frequently the wireless transceiver wakes up to transmit or receive information. Each of the plurality of wake-up schedules for the wireless transceiver may be different from another one or the plurality of wake-up schedules for the wireless transceiver. The method may further comprise automatically switching between the plurality of wake-up schedules for the wireless transceiver such that a duration of time between wake-ups for the wireless transceiver radio is shorter during some predefined times and longer during other predefined times. The duration of time between wake-ups for the wireless transceiver may be configurable by an administrative user via an interface.

Embodiments of the present disclosure disclose an authorization method and an apparatus applied to an electronic lock. The method performed at a server hosting an instant messaging application includes: receiving an authorization request sent by a first instant messaging client at a first terminal, and the authorization request being used for requesting to grant use permission on the electronic lock to a second account; querying for, according to the authorization request, key information bound to the second account; and sending the key information to the electronic lock, the electronic lock being configured to add the key information into a trusted key information store. Moreover, the instant messaging application at the server can also be involved to further enhancing the authenticity of a person who tries to unlock the electronic lock based on the location of a terminal used by the person for accessing the instant messaging application.

Various embodiments may include systems for unlocking a motor vehicle. For example, an apparatus may include: a motor vehicle key for unlocking a motor vehicle having a remote engine start and/or vehicle entry system. The motor vehicle key comprises a Bluetooth antenna and a motor vehicle communication antenna. A controller of the motor vehicle key is configured to: use the Bluetooth antenna to set up a Bluetooth link to a mobile radio terminal using an activation key stored in a memory of the motor vehicle key; and instruct a motor vehicle controller installed in the motor vehicle to prompt an operation of the motor vehicle.
