Abstract: Systems and methods may be used for operation of a hardware fingerprint processing device. A method may include receiving an update including a fingerprint authentication algorithm, verifying a digital signature of the fingerprint authentication algorithm, and in response to verifying the digital signature, loading the fingerprint authentication algorithm into the memory. The loaded fingerprint authentication algorithm may be sued to authenticate a user. For example, a verification method may include receiving information corresponding to an image of a fingerprint, determining whether the fingerprint is authenticated using the fingerprint authentication algorithm, and optionally outputting an indication of whether the fingerprint is authenticated.

Abstract: Various approaches are described herein for enhancing biometric scanning in a biometric scanning system. For example, a porous region of a platen can be wetted with a liquid, the porous region sized and shaped for contact with skin of a subject (such as a finger or palm), and the porous region defining respective pore structures to house the liquid for wetting the skin when the skin is in contact with the porous region. Topological features of skin in contact with the porous region can be imaged, such as ridges of a fingerprint. The topological features generally contrast with a background field illuminated by a light source, with contrast enhanced in response to a presence of the liquid versus no liquid being present.

Abstract: Disclosed herein are systems and methods for entangled authentication of biometric sensors and biometric-sensor outputs. In an embodiment, a secure-biometric-sensor system includes a biometric sensor and a secure element physically bound to one another. The sensor is communicatively interposed between a host and the secure element. The sensor receives a cryptographic challenge from the host and forwards it to the secure element. The sensor captures a biometric reading and transmits it to the host. The sensor receives, from the secure element, a challenge response that includes a shared secret between the host and the secure element. The sensor generates a cryptographically entangled token from a predetermined combination of the shared secret and data specific to the captured biometric reading, and transmits the cryptographically entangled token to the host for use by the host in attempting to authenticate the biometric reading as having been captured by the sensor.

Abstract: Systems and techniques may be used for allowing a person access to a secure area, opening a door, or the like. A technique may include detecting a person within a particular distance of a secure area, capturing, using a camera, a set of images of at least a facial feature of the person, preprocessing the set of images to identify the facial feature in at least one image of the set of images, and identifying, using processing circuitry, a gaze status of the person based on the identified facial feature in the at least one image. The technique may include determining, using a trained machine learning model, an intent of the person to access the secure area based on the gaze status, and based on determining the intent, granting access to the secure area.

Abstract: A radio frequency identification (RFID) tag including a face stock layer, an antenna inlay beneath the face stock layer and comprising a radio frequency (RF) antenna and an integrated circuit (IC) chip, a spacer layer beneath the antenna inlay, and a metal ground plane. The antenna inlay may include a near-field communication (NFC) or high frequency (HF) antenna, and optionally may include an ultra-high frequency (UHF) antenna. The spacer may be made of a flexible polypropylene, and the metal ground plane may be made of aluminum.

Abstract: A physical access control (PAC) system comprises an authentication device that includes physical layer circuitry and processing circuitry. The physical layer circuitry transmits and receives radio frequency electrical signals over a radio access network. The processing circuitry is operatively coupled to the physical layer circuitry and includes an authentication engine. The authentication engine is configured to receive access credential information via the radio access network using a cloud-based messaging service; authenticate the access credential information using the authentication device; and initiate access to a physical access portal according to the access credential information.

Abstract: Methods and systems are provided for changing an encryption key for biometric templates in a database without changing the content within the database. A first biometric template is encrypted with a first encryption key to create a first encrypted first biometric template. A transformation is applied to the first encrypted first biometric template to create a second encrypted first biometric template. A second encryption key is generated based on the first encryption key and the transformation permitting the use of the second encryption key to compare presented biometrics encrypted with the second encryption key with templates stored in the database.

Abstract: Systems and methods are described for securing credentials with optical security features formed by quasi-random optical characteristics (QROCs) of credential substrates. A QROC can be a pattern of substrate element locations (SELs) on the substrate that includes some SELs that differ in optical response from surrounding SELs. During manufacturing, a QROC of a substrate can be characterized, hidden by a masking layer, and associated with a substrate identifier. During personalization, personalization data can be converted into an authentication graphic formed on the substrate by de-masking portions of the masking layer according to a de-masking pattern. The graphic formation can result in a representation that manifests a predetermined optical response only when the de-masking pattern is computed with knowledge of the hidden QROC. The authentication graphic and optical response can facilitate simple human authentication of the credential without complex or expensive detection equipment.
