Abstract: A secure performance monitoring unit of a processor includes one or more performance monitoring counters and a secure group manager. The secure group manager is configured to receive a request to create a secure counter group from a software (SW) process being executed by a processor, the request including identification of the one or more counters; determine availability of the one or more counters, creating the secure counter group, assign the one or more counters to the secure counter group, and save a public key of the SW process, when the one or more counters are available; receive and save a private key for the secure counter group; receive a request to configure the secure counter group from the SW process; verify the configuration using the public key of the SW process; and begin sampling of the one or more counters when the configuration is verified.

Abstract: A user authentication system and method. A two-dimensional image of a scene is obtained and range information obtained from the scene is aligned with the two-dimensional image. One or more depth regions is identified and image segments corresponding to the one or more depth regions are selected within the two-dimensional image. Brightness operations are performed on one or more of the selected image segments to form a corrected image.

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: 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: In one embodiment, a first device includes: a first logic to generate a first token when a user adapts the first device in approximate contact to the user, the first token including a first timestamp; a storage to store the first token and a second token, the second token obtained from an authenticator and associated with an authentication of the user to a second device, the second token including a second timestamp; and a communication module to communicate the first and second tokens to the second device to cause the second device to authenticate the user based at least in part on the first and second tokens. Other embodiments are described and claimed.

Abstract: A system and method for capturing an image of a user. An image is captured with a camera, wherein the image includes a user's image. A first avatar is displayed in a display, wherein displaying includes positioning an avatar in at least some of the user's image. The user is then encouraged to move so the first avatar moves to a second position in the display.
