Abstract: Some embodiments include a method of providing security and privacy for a message sender. The method can include a messaging application determining that a messaging interface of the computing device is active and is revealing or about to reveal the electronic message. The messaging application can identify a recipient account of a messaging server system that is associated with the electronic message according to the electronic message or the messaging server system. The messaging application can then monitor a data feed from a sensor of the computing device to detect a biometric pattern that matches against a biometric profile model associated with the recipient account utilizing a biometric recognition process. In response to determining that the detected biometric pattern does not match the biometric profile model associated with the recipient account, the messaging application can activate a privacy shield to prevent content of the electronic message from being revealed.

Abstract: Embodiments of the invention are generally directed to using breath measurement to identify certain physiological states, conditions and disorders. In one example, breath measurement may be used in producing a non-binary indicator of the likelihood or extent to which a subject is experiencing or approaching ketosis. Other metabolic or respiratory states may be indicated and/or identified.

Abstract: Some embodiments are directed to determining the composition of breath exhaled by a subject. For example, some embodiments are directed to determining a concentration of a gas species in breath exhaled by a human subject, based at least in part upon a measured concentration of the gas species in a chamber which is adapted to hold both breath exhaled by the human subject and ambient air for inhalation by the human subject.

Abstract: A biometric authentication platform (10) uses fault-tolerant distributed computing to determine if a supplied biometric sample and a sample stored in a registry are from the same person. A collection of reference samples is maintained in a distributed ledger (115) with immutable history of modifications. Results of matching are stored in a separate distributed ledger (125) providing an immutable history log. Coordinated use of both ledgers (115, 125) enable biometric authentication of registered users (140) in real time. Users (140) may interact with providers (150) and/or trusted circles of other users in order to recover user records from the user ledger (115).

Abstract: Systems and methods are disclosed for temporal sampling of air exhaled by a user. Some embodiments comprise a mask adapted to be worn by a user, a chamber, disposed in or on the mask, the chamber comprising a valve, at least one sensor, disposed in the chamber, for measuring composition of air, an actuator adapted to open the valve, and at least one processor. The at least one processor is programmed to selectively instruct the actuator to open the valve, thereby causing air in the mask to be exposed to the at least one sensor, at a time associated with exhalation by the user, and to selectively instruct the actuator to close the valve, thereby preventing air from entering the chamber, at a time associated with inhalation by the user.

Abstract: Medical diagnostic images that are embedded with contact messages about a professional are sent to a patient for sharing with others. Although the images may be obtained using any of a variety of imaging devices, in some instances, the images may be obtained using a soft-tissue-injury diagnostic system for diagnosing soft tissue injury within a patient. A visual display is configured and arranged for receiving and displaying the medical diagnostic image. Personalized contact messages are then embedded within the image as a watermark to with information about the professional, such as an electronic business card, contact information, or hyperlinks to additional information. The sharable image with embedded messages is electronically sent to the patient for sharing with others. Personalized contact messages may also be embedded in non-medical images for sharing with others.

Abstract: The present invention describes a device and method for touchless palmprint acquisition. The method can be applied to a terminal device (including but not limited to mobile phones, tablet computers and other portable devices) with a display screen and a front-facing camera. The camera is used to capture images of palms. The screen is used as a supplementary light source. When lighting condition in the palm area is undesirable, the screen changes its display to improve the lighting condition inside the palm, which increases the recognizability of the palmprint. The palmprint acquisition device and method described in the present invention can be directly applied to existing terminal devices without requiring any additional hardware. By adopting a variety of ways to change the display of the built-in screen of the terminal device, the lighting condition of the palm area will be improved and the recognizability of the palmprint will be increased.

Abstract: Some embodiments are directed to a self-contained breathing mask for measuring and monitoring the breath of a human subject. The mask may be lightweight, self-contained, and physically untethered to any test or measurement equipment, providing the subject full mobility, and allowing him/her to perform almost any daily activity during use. The mask may include integrated sensors for measuring properties of the subject's breath, over any length of time, providing respiratory information like breath count, rate and volume, oxygen consumption, and carbon dioxide production, as well as various biometric information.

Abstract: A computing platform is described to match a palm digital representation to a palm template. The platform includes logic causing presenting a viewfinder image including an image stream and/or a cue appearing to reside substantially in front of a user to guide the user to align a palm at a position within a field of view of a camera; capturing a set of images using the camera; processing the set of images to determine a set of identifying features of the palm; and comparing the set of identified features with enrolled palm prints to identify the palm.

Abstract: Some embodiments include a messaging system capable of expression-based communication and/or expression-based actions. The messaging system can run on a computing device. For example, the messaging system monitors a camera feed from a camera of the computing device to detect a biometric signature when a messaging interface of the messaging application is actively being used. The messaging system can match the detected biometric signature against a known profile utilizing a facial recognition process to authenticate an operating user to use the messaging application. The messaging system can determine a human expression based on the detected biometric signature utilizing an expression recognition process to associate a contextual tag with an activity on the messaging interface. The messaging system can then communicate with a message server system to associate the contextual tag with content presented to the operating user or a conversation participated by the operating user via the messaging application.

Abstract: A biometric feedback system for providing biometric feedback to a subject while the subject performs a controlled physical movement includes an applied-force-recording interface and at least one controller electrically coupled to the applied-force-recording interface. The at least one controller receives applied force from the subject during the controlled physical movement and the applied-force-recording interface records data related to the applied force. The biometric feedback system also includes a dynamic surface electromyograph (“sEMG”) device that detects muscle tension along at least one muscle group of the subject while the subject performs the controlled physical movement and records data related to the muscle tension. A hub receives and processes data from the applied-force-recording interface and the dynamic sEMG device. A visual display displays the processed data from the hub.

Abstract: Embodiments are directed to a communication-session (CS) module that monitors the status of a communication session and at least partially controls the status. The CS module provides a party participating in a communication session an indication of whether a status of a microphone the user is employing to participate in an audio and/or video communication session is in a mute (or off) state, or whether the microphone status is in a live (or on) state. Likewise, a CS module may indicate to a user whether a status of a camera that the user is employing to participate in a video communication session is in an off state, or whether the camera status is in an on (or live) state. As such, a CS module provides users reminders of whether or not the microphone and/or camera, is in a live state, a mute state, or is otherwise turned on or off.
