Abstract: Techniques for obfuscating user selections during user-input of sensitive information, involving displaying several targets, such as keys of a virtual keyboard, on a display device, where each target corresponds to one of multiple options. When a first visual indication of a current user target moves to a first target in response to a first movement of a user pointer to a first position within the first target, the obfuscation system can be configured to concurrently move a second visual indication of a first distractor target to another target. The current user target is thus obfuscated as two different visual indicators and/or pointers move through the targets.

Abstract: Disclosed in some examples are devices, systems, methods, and machine-readable mediums which provide for a network-based communication service that allows users in a network-based communication session to subscribe to video streams of the communication session that are of interest by subscribing to content features of those video streams rather than the video streams themselves. Content features may be any object in the video stream that is recognized by applying an image processing algorithm to one or more video frames. Example content features may include recognized users and/or other recognized objects.

Abstract: An agent interfaces with a sending computing device and a receiving computing device to automatically adjust one-way or two-way real-time audio and real-time video transmission parameters responsive to changing network conditions and/or application requirements. The agent incorporates a reinforcement learning model that adjusts transmission parameters to maximize an expected value of a sum of future rewards; the expected value of the sum of future rewards is based on a current state of the sending computing, a current action (e.g. a current set of transmission parameters) at the sending computing device and a reward provided by the receiving computing device. The reward is representative of a user-perceived quality of experience at the receiving computing device.

Abstract: Techniques for obfuscating selection of an option during user-input of sensitive information, involving displaying several targets, such as via a virtual keyboard, on a device display, where each target corresponds to one of multiple options. When a first visual indication of a current user target moves to a first target in response to a first user navigation input, an obfuscation system can concurrently or soon thereafter move a second visual indication of a first distractor target to another target. The current user target is thus obfuscated as two different visual indicators move through the targets.

Abstract: Techniques for obfuscating user selections during user-input of sensitive information, involving displaying targets, such as keys of a virtual keyboard, on a display device, where each target corresponds to one of multiple options. A visual indication for a current user target can move to a first target in response to a first input event at a first time, and the first target can be actuated in response to a second input event for actuation of the current user target at a second time. An obfuscation system is configured to present to a user, at approximately the second time, a discriminatory signal used to confirm actuation of a target. The discriminatory signal includes one of a haptic signal generated by a device in physical contact with the user, an audio signal, and a modified image.

Abstract: Techniques for obscuring user touch input actions during user-input of sensitive information, relating to the display of targets, such as keys of a virtual keyboard, on a display device, where each target corresponds to one of multiple options. When a touch input is performed by a first digit at a first position on a touch interface surface, a visual indicator of a current user target moves to a first target in response. While the first digit remains in continuous contact with the touch interface surface, a second touch input event may be performed by a second digit being at a second position on the touch interface surface different from the first position. The visual indicator moves to a second target in response. A current user target is actuated upon detection by an obfuscation system of the first input event and the second input event.

Abstract: User-input obfuscating techniques involving displaying multiple targets on a display device. A visual indication of the current user target moves to a first target at a first time in response to user input, and a first presentation of a visual or audio feedback signal confirming actuation of a target occurs at a second time, without a user input for actuation of a target received while the current user target has remained at the first target from the first time to the second time. The visual indication moves to a second target at a third time in response to user input. The second target is actuated in response to receiving user input for actuation of the current user target after the third time. Then, with the current user target having remained at the second target since the third time, a second presentation of the visual or audio feedback signal is provided.

Abstract: Techniques for obfuscating user selections during user-input of sensitive information, involving receiving a user input entered via a user input device and, in response, causing a first visual indication to move over a period of time through a first subset of displayed targets to enter user selections of targets. In a concurrent process, control signals are generated to display a second visual indication in addition to the first visual indication. The second visual indication moves through a second subset of the displayed targets during the period of time in a manner that is different from the first visual indication moving through the first subset of the displayed targets. The current user target is thus obfuscated as two or more different visual indicators move through the displayed targets.

Abstract: Techniques for obfuscating user selections during user-input sessions in which potentially sensitive information is being identified, involving displaying several targets, such as keys of a virtual keyboard, on a display device, where each target corresponds to one of multiple options. While a current user target is associated with a visual indicator at a first time, a discriminatory signal indicating the visual indication displayed at the first time is for the current user target is provided, where the discriminatory signal includes one of a haptic signal generated by a device in physical contact with the user, an audio signal, and a modified image. Concurrently, the obfuscation system is configured to present another visual indication corresponding to a current distractor target. The current user target is thus obfuscated as two different visual indicators are presented and move through the group of options.

Abstract: An improved method and system for varying an amount of mechanical coupling in a speakerphone is disclosed. Solutions and implementations provided vary the amount of mechanical coupling between one or more speakers and one or more microphones of the speakerphone to generate high-quality sounds. Implementations include receiving an input signal, sending a copy of the input signal to a first speaker, performing a signal transformation on the input signal to produce a transformed input signal, and transmitting the transformed input signal to a second speaker, where the first speaker generates a first vibration force in response to the input signal, and the second speaker generates a second vibration force in response to the transformed input signal, the second vibration force being in an opposite direction to that of the first vibration force and offsetting at least part of the first vibration force.
