Abstract: Systems and methods for access control systems includes first and second access facilities, and first and second readers. The first reader is configured to control access through the first access facility. receive a credential using a first communication protocol from a device that stores the credential, and establish a secret with the device using the credential. The second reader is configured to control access through the second access facility. The first reader is configured to provide the secret to the second reader, and the second device is further configured to perform ranging using the secret and a second communication protocol different than the first communication protocol to identify intent information. Access through one of the first facility or the second facility is coordinated using the intent information.

Abstract: The use of multimodal face attributes in facial recognition systems is described. In addition, use of one or more auxiliary attributes, such as a temporal attribute, can be used in combination with visual information to improve the face identification performance of a facial recognition system. In some examples, the use of multimodal face attributes in facial recognition systems can be combined with the use of one or more auxiliary attributes, such as a temporal attribute. Each of these techniques can improve the verification performance of the facial recognition system.

Abstract: This disclosure describes techniques for updating firmware of a secure element. The techniques include operations comprising: receiving, by a gateway device, from a remote source, a firmware file; receiving, by a processing element implemented on the gateway device, ephemeral session specific key material for a first secure element implemented on the gateway device; dividing the firmware file into a plurality of data chunks; applying, by the processing element, the ephemeral session specific key material to a first data chunk of the plurality of data chunks to generate a first data packet; and sending, by the processing element, the first data packet to the first secure element.

Abstract: Systems and techniques for a physical access control systems with localization-based intent detection are described herein. In an example, an access control system may regulate access to an asset. The access control system is adapted to establish a first connection with a key-device. The access control system may be further adapted to receive a credential for a user over the first connection. The access control system may be further adapted to establish a second connection with the key-device. The access control system may be further adapted to determine an intent of the user to access the asset. The access control system may use location data derived from the second connection to determine the intent of the user. The access control system may be further adapted to provide the credential to an access controller, based on identifying an intent of the user to access the asset.
