    Abstract: System and techniques for spoofing detection in image biometrics are described herein. A sequence of images may be obtained from a camera; a first plurality of images in the sequence of images including a representation of a user body part, and a second plurality of images in the sequence of images including a representation of an environment of the user. A marker may be created for the representation of the body part. A feature of the environment of the user present during the second plurality of images may be identified in the sequence of images using a third group of circuits. A correlation between the marker and the feature of the environment in the sequence of images may be quantified to produce a synchronicity metric of the degree to which the marker and the feature of the environment correlate.

    Abstract: Various systems and methods are provided for implementing a software defined industrial system. In an example, self-descriptive control applications and software modules are provided in the context of orchestratable distributed systems. The self-descriptive control applications may be executed by an orchestrator or like control device, configured to: identify available software modules adapted to perform functional operations in a control system environment; identify operational characteristics that identify characteristics of execution of the available software modules that are available to implement a control system application; select a software module for execution based on the operational configuration and the operational characteristics identified in the manifest; and cause the execution of the selected software module in the control system environment based on an application specification for the control system application.

    Abstract: Technologies for end-to-end biometric-based authentication and locality assertion include a computing device with one or more biometric devices. The computing device may securely exchange a key between a driver and a secure enclave. The driver may receive biometric data from the biometric sensor in a virtualization-protected memory buffer and encrypt the biometric data with the shared key. The secure enclave may decrypt the biometric data and perform a biometric authentication operation. The computing device may measure a virtual machine monitor (VMM) to generate attestation information for the VMM. A secure enclave may execute a virtualization report instruction to request the attestation information. The processor may copy the attestation information into the secure enclave memory. The secure enclave may verify the attestation information with a remote attestation server. If verified, the secure enclave may provide a shared secret to the VMM. Other embodiments are described and claimed.

    Abstract: Systems and techniques for facial spoofing detection in image based biometrics are described herein. A marker may be created for a representation of a face in a first plurality of images of a sequence of images. The marker corresponds to a facial feature of the face. An environmental feature of an environment of the face may be identified across a second plurality of images of the sequence of images. A correlation between the marker and the environmental feature in the sequence of images may be quantified to produce a synchronicity metric. A spoofing attempt may be indicated in response to the synchronicity metric meeting a threshold.

    Abstract: This disclosure pertains to iris recognition including liveness testing. A device may perform iris recognition with testing to check liveness. Sensing circuitry in the device may comprise an IR sensor and IR emitter to generate a uniform IR emission and a pulsed IR emission. Sensor data based on the uniform IR emission may be used for iris recognition, which may be confirmed by at least one test confirming that real eyes are being analyzed and not spoof data. For example, a determination may be made as to whether a light reflection is visible in images captured by the IR sensor, whether the light reflection is aligned and/or synchronized with an eye center and/or iris center, whether a portion of the iris visible in the captured images changes from image to image, whether the images show that a pupil of the eye is reactive to the pulsed IR emissions, etc.
