Abstract: Systems and methods of improving public key infrastructure using PUF arrays are disclosed. The systems and methods are usable to improve PKI based on Lattice and Code cryptography. In the disclosed system, a client device includes an enrolled PUF array, and a server device acting as a Certification Authority includes an image of the PUF array including previously measured responses data for the devices in the PUF array. The CA sends a set of addresses to the client device, which generates a public key from measuring the response of PUF devices with the addresses. The CA receives the generated public key, and determines that the enrolled PUF was used to generate the key.

By way of example, during the deployment of a heart stent, a specialist doctor may remotely view real-time fluoroscopy imagery and patient hemodynamics. The specialist can remotely proctor medical personnel on the proper orientation and timing requirements for installing the stent.

Abstract: Augmented reality (AR) or virtual reality (VR) systems described herein can be configured to record images, video, and/or annotations for concurrent communication to a remote system for display or subsequent access. A communication between a user and an expert user using the system can include an audio communication (unidirectional or bidirectional), a video communication from the user to the expert user (allowing the expert user to see, in real time, the same environment as the user), and a data communication (via which content overlaid over the video communication, such as annotations, may be displayed for both the expert user and the user). The systems can be configured to communicate concurrently while also creating a recording for later review based on a “live” or current issue being faced by a user assisted by an expert where the communication session is recorded for later playback by other users.

Abstract: Introduced here are approaches to authenticating unknown persons based on variations in the spatial properties and directionality of blood flow through vessels over time. At a high level, these approaches rely on monitoring vascular dynamics to recognize unknown persons. For example, an authentication platform may examine digital images of an anatomical region to establish how a property of the vasculature within the anatomical region changed as a result of deformation. Examples of properties include the position, size, volume, and pressure of vessels included in the vasculature, as well as the velocity and acceleration of blood flowing through the vasculature.

Abstract: Locking mechanisms and methods of operating the locking mechanisms are disclosed. In one example, a locking mechanism may include a main hub assembly coupleable with a deadbolt, a clutch assembly coupled to the main hub assembly, and an actuator assembly coupled to the clutch assembly. The actuator assembly may include an actuator operable to bias a carriage along a first direction to bring the clutch assembly and the main hub assembly closer to one another along a second direction, wherein the second direction is perpendicular to the first direction. The locking mechanism may further include a thumbturn assembly coupled to the clutch assembly, the thumbturn assembly comprising a thumbturn positionable on an exterior side of a door.

Abstract: Devices, methods and graphical user interfaces for manipulating user interfaces based on fingerprint sensor inputs are provided. An electronic device with a display and a fingerprint sensor may obtain fingerprint-verification criteria for controlling verification of fingerprints.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, to verify whether an interaction with a particular content displayed on a content platform is an interaction by an actual human user. A request to generate a click verification token can be received from a first application executing on a client device. The request can include data for a first set of parameters for a first interaction and a first message authentication code (MAC) set. If the first MAC set matches a second MAC set, which is generated using some of the data included in the request, the click verification token can be generated. The click verification token can be provided to the first application, which in turn can provide this token to a content verification system. The content verification can use this token to verify whether the first interaction is an actual human user interaction.
