Embodiments of the present invention are directed to systems and methods for preventing unauthorized access to server racks. In one example, a system includes an electronic key and an electronic lock configured to be attached to the server rack. The electronic lock is configured to communicate with the electronic key for determining whether the electronic key is authorized to unlock or lock the lock. The electronic lock includes a handle configured to be disengaged from the electronic lock when the electronic key is authorized, and the handle is configured to be actuated to unlock the lock for accessing the server rack when the handle is disengaged from the electronic lock. The electronic lock is configured to re-lock only when the handle is engaged with the electronic lock.

The present invention relates to an electronic key interlocked with a smart device and an electronic key interlocked with a smart device according to an exemplary embodiment of the present invention includes a first transmission and reception unit which is electrically connected to a smart device to transmit and receive data, a second transmission and reception unit which is electrically connected to an electronic locking device to transmit and receive data, and a power supply unit which is supplied with power from the smart device to supply the power to drive the electronic locking device, and the first transmission and reception unit transmits and receives data for opening and closing the electronic locking device to and from the smart device in accordance with a result of performing user authentication.

An information processing device relates to a predetermined service provided to a user by allowing a worker to temporarily access a vehicle cabin including a trunk of a vehicle used by the user. The information processing device includes a processor. The processor is configured to determine whether the worker relating to a service provider of the service has unlocked a door of the vehicle using key information for unlocking the door, the door accessing the vehicle cabin of the vehicle, and notify the user of a warning or activate an alarm device of the vehicle, in a case where the processor determines that the door has been unlocked and in a case where the processor determines that a state in which the door of the vehicle is not locked continues after a predetermined time has elapsed from unlocking of the door.

A key, a lock core and a lock, relating to a key, a lock core and a lock are provided. The key includes: a column body, a first end of the column body being provided with a light emitting component; a first cathode component disposed on the column body and connected to one end of the light emitting component to be mated with a second cathode component in the lock core; a first piezoelectric electrode disposed on the column body and connected to the other end of the light emitting component to be pressed against a second piezoelectric electrode in the lock core. When the first cathode component is mated with the second cathode component in the lock core, and the first piezoelectric electrode is pressed against the second piezoelectric electrode in the lock core, a piezoelectric current is generated, to cause the light emitting component to emit light.

A smart card with a fingerprint sensing system, includes a controller and a fingerprint sensing device. When the fingerprint sensing device senses a fingerprint to generate a fingerprint frame data, the controller enters a sleep mode, and when the controller reads the fingerprint frame data, the fingerprint sensing device stops sensing the fingerprint. Since operations of sensing the fingerprint and reading the fingerprint frame data do not occur at the same time, the high current condition can be avoided so as to decrease power consumption.

An electronic key storage device including an openable and closable door and a plurality of key holders includes a storage unit configured to store key information of an electronic key usable for each registered user and location information of the key holder matching the electronic key, a user authentication unit configured to perform user authentication by receiving user authentication information so that the door is openable or closable, and a control unit configured to control a fastening operation of the key holder to put the electronic key in the key holder and take the electronic key out of the key holder.

Present disclosure relates a secure electronic lock system. Secure electronic lock system includes many secure electronic locks connected through a communication network to a secure electronic lock system server. Each secure electronic lock includes a passive electronic lock, an active electronic key and a passive electronic key. Active electronic key includes electrical power source providing electrical power supply to active electronic key, passive electronic lock and passive electronic key. When both active and passive electronic keys are inserted into respective electronic keyholes of passive electronic lock, both active and passive digital keys are transmitted to passive electronic lock, passive electronic lock can be locked and unlocked only when both active and passive digital keys received match prestored active and passive digital keys respectively. Active and passive digital keys are updated and an access event is transmitted to secure electronic lock system server every time each secure electronic lock is accessed.

Presented are vehicle control systems and logic for monitoring device batteries to provision virtual key functionality, methods for making/using such systems, and vehicles equipped with such systems. A method of operating a vehicle includes wire or wirelessly connecting a remote keyless entry (RKE) system with a wireless-enabled portable electronic device (PED) of a user. A vehicle controller receives a unique virtual key code from the user's PED to enable use of the RKE system and, after receiving the virtual key code, determines a battery charge level of the PED's battery. The vehicle controller then determines if the battery charge level is less than a preset minimum charge level and if the vehicle powertrain is off. If the powertrain is off and the battery charge level is less than the minimum charge level, the controller responsively commands a resident vehicle subsystem to execute a control operation for charging the PED battery.
