Patent number: 11301703Abstract: A biometric access control system for controlling access to an environment based on an authorization status of a living subject is disclosed. In one example, a data source generates image data of a tissue region of the subject. A liveness measurement unit processes the image data to detect changes over at least one of time or spatial volume in one or more structural features of the tissue region and generates, based on the detected changes, a spoofing attack detection status indicating that the image data is from living biological tissue or that a spoofing attack is detected. A biometric identification unit processes at least a portion of the same image data generated by the data source to generate biometric information indicative of an identity of the subject. Responsive to the spoofing attack detection status and the biometric information, an authorization unit outputs an authorization status for the subject.Type: GrantFiled: March 21, 2018Date of Patent: April 12, 2022Assignee: SRI InternationalInventors: Jeffrey Lubin, James R.

Patent number: 10949692Abstract: Techniques for verifying identity of a human subject to an identification document are described. In some examples, a computing device may be connected to least two cameras oriented such that a first field of view is a substantially opposite direction from a second field of view. The device may receive images from the first camera that include a human subject. Second images from the second camera may include images of an ID document with a photograph of the human subject. The device may process the first images along with the respective, corresponding second images to determine respective 3D locations for at least one of cameras at the respective times the images were captured. Based on the sequence of 3D locations, along with the first images and the second images, the device may determine whether the human subject is a valid human subject.Type: GrantFiled: March 8, 2019Date of Patent: March 16, 2021Assignee: SRI InternationalInventors: Jeffrey Lubin, James R.

Publication number: 20200341114Abstract: An identification system includes a radar sensor configured to generate a time-domain or frequency-domain signal representative of electromagnetic waves reflected from one or more objects within a three-dimensional space over a period of time and a computation engine executing on one or more processors. The computation engine is configured to process the time-domain or frequency-domain signal to generate range and velocity data indicating motion by a living subject within the three-dimensional space. The computation engine is further configured to identify, based at least on the range and velocity data indicating the motion by the living subject, the living subject and output an indication of an identity of the living subject.Type: ApplicationFiled: March 28, 2018Publication date: October 29, 2020Applicant: SRI InternationalInventors: Girish Acharya, Douglas Bercow, John Brian Burns, Bradley J.

Patent number: 8189858Abstract: Visually imperceptible distortion, from watermarking or compression, desired for embedding into frames of a video sequence is computed. Within each spatiotemporal region of the frames, points are counted, which have feature information amplitude that at least equals the desired distortion. In each region, a fraction of the points with magnitudes at least equal to desired distortion is determined, in relation to the total number of points and compared to a threshold. Regions with fractions at least equal to the threshold are identified. Visual aspects of features in the identified regions are analyzed for salience related to drawing visual attention. The salience is compared to a threshold. Identified regions that do not exceed the salience threshold may be selected as candidates for hiding the watermark. Spatial and temporal contrast values may relate to the salience, as well as luminance values computed therewith.Type: GrantFiled: April 27, 2009Date of Patent: May 29, 2012Assignee: Dolby Laboratories Licensing CorporationInventor: Jeffrey Lubin
