An input authentication method includes a processing unit generating a lead code according to a predetermined character string, wherein the predetermined character string includes a plurality of randomly arranged characters, the lead code is composed of N characters selected from the predetermined character string, and N is a positive integer; displaying the lead code on an input interface; the input interface receiving a first input; and when the first input corresponds to the N characters of the lead code, the processing unit performing a predetermined operation.

A system is provided wherein a network control access device that is already in a network, called a Gatekeeper, generates a random short password in the form of a series of audio or visual cues that are visible to the user of a joining device. The joining device can be a simple one button device, or even a no-button device that is part of the internet of things (IOT) standard. The response to each cue can be entered by the user on a single-button joining device. For a no-button joining device, an alternate input method may be utilized on the joining device in response to the audio and visual cues. Alternatively, a password can be generated by the no-button joining device and be entered by the user one bit at-a-time directly onto the Gatekeeper keypad. Once the password is received, the Gatekeeper performs a password verification procedure.

A system includes a processor configured to determine that a number of invalid attempts to input a code into a vehicle door keypad has passed a predetermined threshold. The processor is also configured to notify a registered user through a vehicle telematics system of the invalid attempts and selectively ignore future attempts to input the code.

In a locker apparatus, an operation unit includes authentication means, and a control device locks a locking device in order to bring a door into a closed state except when luggage is deposited in a box and when the luggage is taken out from the box. The operation unit includes a reopening door button for giving an instruction to reopen the door. When the reopening door button is operated within 15 minutes after the luggage is deposited in the box, the door is closed, and the locking device is locked once, the control device unlocks the locking device, on a condition that authentication by the authentication means is established, in order to permit the door to be reopened, and locks the locking device again when the door is closed thereafter.

A system for controlling a locking device of a container for storing a hazardous chemical includes a display that displays safety information relating to storage and use of the chemical, a camera that captures an image of an operator, and a controller in communication with the locking device, the display, and the camera. The controller is configured to deactivate the locking device when a request is received from the operator for physical access to the chemical, a confirmation is received that the operator has correct acknowledgement and understanding of the safety information, and a requirement for personal protective equipment relating to the chemical is determined to be satisfied based on the image.

In some implementations, a device may receive an indication of a code associated with granting authenticated access to a door. The device may transmit, to a user device, presentation information to cause an augmented reality image of an input pad to be displayed by the user device, wherein the augmented reality image is displayed over an area of an image of an exterior of the door via a user interface. The device may detect, via a camera device, one or more user inputs to the area of the exterior of the vehicle based on tracking a movement of a user. The device may identify an input code based on the one or more user inputs. The device may perform an action to cause the door to be unlocked based on the input code matching the code.
