A mobile device is configured to wirelessly authenticate with a reader device. The mobile device may receive an acoustic signal from a user, and a command may be determined based on the acoustic signal. The mobile device may transmit the command to the reader device if the mobile device and the reader device are authenticated. The reader device may receive the command, and may analyze the command to determine an action to be performed. The reader device may then perform the action if the mobile device is authorized to request the command to be performed.

Example vehicle unlocking methods and apparatus are described. In one example method, wakeup keyword detection is performed on an obtained voice signal. If the voice signal includes a wakeup keyword, an acoustic source direction is determined, and a target camera is indicated to collect image data. The target camera is a target camera that is installed on the vehicle and whose angle of view can ensure that the acoustic source direction is captured. Then, the vehicle is unlocked based on the image data collected by the target camera.

There is provided a method and a system for authorizing a user device to send a request to a vehicle in order to prevent a physical layer relay attack. The system comprises a vehicle comprising an acoustic transducer and an RF transceiver and a user device comprising an acoustic transducer and an RF transceiver. The method relates to a signaling scheme using a combination of acoustic and RF signals for preventing a successful physical layer relay attack.

A method for access control in an access control system for vehicles is proposed comprising at least one access control device, in the context of which by a display device of the at least one access control device facing an incoming vehicle in the access direction, a unique text assigned to the respective access control device is displayed which, due to the design and/or arrangement of the display device, is only visible in a defined area around the access control device. Under normal operating conditions, only one vehicle can be located in the defined area around the access control device. The displayed text is used to control the access control device in accordance with data transmitted to the access control system by a mobile electronic device (1), into which the text is dictated by a user.

Provided is an information processing apparatus including: a locking control unit configured to execute a first process of processes for causing a locking unit to unlock, on the basis of detection of access of a first communication terminal; and a detection unit configured to detect an unlocking request by a user of the first communication terminal. The locking control unit executes a second process of the processes for causing the locking unit to unlock, when the unlocking request is detected and the first process is completed.

Disclosed is a system that uses a window as a microphone as a replacement for keyless entry to a vehicle. The system includes a window which acts as a microphone using a piezoelectric transducer that captures resonance on an outside surface of the vehicle window when pressure waves (e.g., voice commands or taps) impact it. To recognize this sound, a transducer controller amplifies vibrations from the window tap or spoken commands. The system may include a low-power mode that listens for input while the vehicle is off. In a second, high-power mode, the system may detect a tapping event, which may prompt a transition to a wake-up state. The system may associate a number and timing of taps with unique user keys, similar to key selections of numbers on a keypad. The system may also recognize verbal PIN code input using the piezoelectric transducer microphone.

Systems and methods for driver identification using vehicle approach vectors are disclosed. An example disclosed vehicle includes a plurality of beacons configured to connect to a first mobile device and a second mobile device. The example vehicle also includes a plurality of ultrasonic sensors. The example vehicle includes a driver identifier configured to predict trajectories for the first and second mobile devices based on information received from the plurality of beacons and the plurality of ultrasonic sensors, and determine which one of the mobile devices is associated with a driver based on the predicted trajectories.

Provided is an information processing apparatus including: a locking control unit configured to execute a first process of processes for causing a locking unit to unlock, on the basis of detection of access of a first communication terminal; and a detection unit configured to detect an unlocking request by a user of the first communication terminal. The locking control unit executes a second process of the processes for causing the locking unit to unlock, when the unlocking request is detected and the first process is completed.

Methods and systems for improved exit detection, payment confirmation, and payment authorization verification are provided. In one embodiment, a method is provided that includes transmitting an audio transmission that includes a unique identifier of a facility. The audio transmission may be transmitted to a computing device, which may transmit in response an audio transmission containing a unique identifier and a payment confirmation identifier. The payment confirmation identifier may be compared to a database of payment information and it may be determined that the payment confirmation identifier corresponds to a completed payment. It may further be determined that the user has completed a payment and is permitted to exit the facility.
