A control method for opening a tail gate for a vehicle capable of performing an auto opening operation of the tail gate includes steps of primarily sensing an intention of a user carrying a smart key to open the tail gate and then performing secondary sensing to confirm whether a distance between the smart key and the tail gate is equal to or more than a predetermined distance. Thus, any damage or interference of the tail gate may be prevented.

A vehicle includes a processor programmed to validate, using a public key of a lender device, authenticity of a file including permissions for a borrower device signed using a private key of a lender device, and responsive to validating, using a public key of a borrower device, a session request from the borrower device signed with a private key of the borrower device, establish a secure connection with the borrower device over which access to the vehicle is granted per the permissions.

An authentication method used in a server, includes: acquiring check-in information sent by user equipment (UE) of a user, wherein the check-in information includes information on the user and a check-in period; determining information on a room of the user based on the check-in information; sending the information on the room to the UE; determining unlocking information based on the check-in information; and sending the unlocking information to at least one of the UE or door lock equipment corresponding to the information on the room, wherein the door lock equipment is configured to authenticate the user based on the unlocking information during the check-in period, the unlocking information being invalid other than during the check-in period.

An apparatus for more efficiently enabling secure access to an enclosure is described herein. The apparatus may include a wireless transmitter in a selectably opaque container, a wireless transceiver, a GPS receiver, an NFC transmitter and/or receiver, one or more hardware processors, and hardware memory. The hardware memory stores instructions for receiving a current location of the apparatus and comparing that location to a delivery address of the enclosure. As the location is within a certain range of the delivery address the apparatus sends a request to a cloud-based server for a hash digest masking an acceptable input for an access control mechanism associated with the enclosure. The apparatus receives the hash digest and forwards it to the access control mechanism via the wireless transmitter. Computer executable code for handling such tasks, and a cloud-based server for generating the hash digest, are also described herein.

A communication device includes a communication control unit generating a communication signal to be transmitted to an external source and an encryption unit connected to the communication control unit through a wiring. The communication control unit stores a predetermined communication signal indicative of a predetermined message and a target duration required for from a transmission of the predetermined communication signal to a reception of the same from the encryption unit. The communication control unit further counts an actual duration taken from the transmission of the predetermined communication signal to the reception of the same from the encryption unit. When the actual duration is longer than the target duration, the communication control unit determines that a fraudulent circuit is inserted into the wiring for fraudulently acting on the communication signal.

Disclosed are various approaches for providing touchless visitor management. A visitor can complete a visitor registration process using a client device of the visitor and obtain a virtual badge credential to a visitor's device. A physical access control system credential as well as a visitor badge can also be obtained to the visitor's device.

There is a need to accurately and dynamically generate a time-based prediction and control access to the time-based prediction. This need can be addressed, for example, by allowing controlled access to user information pertaining to a user visiting a facility. In one example, a method includes storing a companion user identifier in association with a public user identifier; receiving a request for a user status of the user; determining whether the companion user is permitted to receive the user status of the user based at least in part on the public user identifier and the companion user identifier; responsive to determining that the companion user is permitted to receive the user status of the user, requesting an aggregated time-based prediction for the user; and causing, the aggregated time-based prediction to be decrypted and provided as a response to the request for the user status of the user.

Systems and methods for phone-as-a-key range extension are disclosed. An example disclosed vehicle includes an integrated antenna array with a plurality of antenna located on a roof of the vehicle. The plurality of antenna includes a personal area network antenna. The example vehicle also includes a personal area network module communicatively connected to the personal area network antenna. Additionally, the vehicle includes a key phone unit communicatively connected to the personal area network module. The example key phone unit performs key fob functions as requested by an authorized mobile device.

Embodiments are directed to providing access without determining an identity of a requester. A fixture may receive a rule pertaining to access to a floor of a building. The fixture may receive a request to access the floor of the building. The fixture may grant access to the floor based on a determination that the rule indicates that access to the floor should be granted.

A control device of the present disclosure includes a receiver configured to receive a function enabling signal transmitted from a portable machine used to manipulate a vehicle, a determination unit configured to measure a predetermined time since the receiver receives the function enabling signal and determine whether the predetermined time elapses, and an opening and closing body controller configured to control opening and closing of an opening and closing body of the vehicle. The opening and closing body controller controls an opening operation of the opening and closing body based on user's action detected by a sensor, which is provided in or around the opening and closing body to detect the user's action, before the determination unit determines that the predetermined time elapses and after the receiver receives the function enabling signal from the portable machine.
