Patent number: 11868455Abstract: Techniques are disclosed relating to biometric authentication, e.g., facial recognition. In some embodiments, a device is configured to verify that image data from a camera unit exhibits a pseudo-random sequence of image capture modes and/or a probing pattern of illumination points (e.g., from lasers in a depth capture mode) before authenticating a user based on recognizing a face in the image data. In some embodiments, a secure circuit may control verification of the sequence and/or the probing pattern. In some embodiments, the secure circuit may verify frame numbers, signatures, and/or nonce values for captured image information. In some embodiments, a device may implement one or more lockout procedures in response to biometric authentication failures. The disclosed techniques may reduce or eliminate the effectiveness of spoofing and/or replay attacks, in some embodiments.Type: GrantFiled: February 22, 2021Date of Patent: January 9, 2024Assignee: Apple Inc.Inventors: Deepti S. Prakash, Lucia E. Ballard, Jerrold V. Hauck, Feng Tang, Etai Littwin, Pavan Kumar Anasosalu Vasu, Gideon Littwin, Thorsten Gernoth, Lucie Kucerova, Petr Kostka, Steven P.

Patent number: 8249334Abstract: A computer-implemented method includes receiving a depth map (30) of a scene containing a body of a humanoid subject (28). The depth map includes a matrix of pixels (32), each corresponding to a respective location in the scene and having a respective pixel value indicative of a distance from a reference location to the respective location. The depth map is segmented so as to find a contour (64) of the body. The contour is processed in order to identify a torso (70) and one or more limbs (76, 78, 80, 82) of the subject. An input is generated to control an application program running on a computer by analyzing a disposition of at least one of the identified limbs in the depth map.Type: GrantFiled: May 10, 2007Date of Patent: August 21, 2012Assignee: Primesense Ltd.Inventors: Tamir Berliner, Ziv Hendel, Alexander Shpunt, Jeffrey Danowitz, Dmitri Rais, Oren Mor, Michael Shpigelmacher

Publication number: 20120202569Abstract: A method, including defining an interaction surface containing an interaction region in space, capturing a sequence of depth maps over time of at least a part of a body of a human subject, and processing the depth maps in order to detect a direction and speed of movement of the part of the body as the part of the body passes through the interaction region. A software application, selected from a group of software applications consisting of a flight simulation and an interactive tennis game, is controlled responsively to the detected direction and speed.Type: ApplicationFiled: March 19, 2012Publication date: August 9, 2012Applicant: PRIMESENSE LTD.Inventors: Aviad Maizels, Ziv Hendel, Tamir Berliner
