摘要： A system and methods are provided for aggregating communication connections. Multiple users connect to a system (e.g., a web-based system) that hosts an application or service for exchanging communications. Users who exchange communications among themselves may be considered “associates.” When one user who is on-line with the application sends a communication through the system for an associate, the system determines whether the associate is on-line or off-line. If the associate is off-line, the system crafts and sends toward the associate a notification regarding the communication, including an address of the communication server to which the one user is connected. When the associate's device receives the notification, the application may attempt to connect to the specified address. In this way associated users' connections will aggregate or gravitate toward the same communication server, thereby eliminating the latency and cost of exchanging users' communications between multiple communication servers.

摘要： A system and methods are provided for dynamically muting or suppressing notifications of new communications. When a new communication is received for a user of a communication device (e.g., a mobile telephone, a computer) while notifications are muted, no notification may be issued to the user or, alternatively, a muted notification that differs from a normal notification may be issued. A muted notification may have muted sound or no sound, abbreviated vibration or no vibration, or may otherwise be a dampened version of a normal notification. Dynamic muting may be applied or managed on the user's device or on a system that hosts the communication application for which notifications are muted. Different applications and/or communication sessions (e.g., different chat groups) may be muted differently (e.g., for different periods of time). When a group chat session is muted, the duration of muting may be proportional to the number of participants.

摘要： A system and method for detecting unwanted electronic content, such as spam. As a user operates an application to send messages, several metrics are tracked to allow the system to analyze her activity. Illustrative metrics may include, but are not limited to, block count (e.g., how many other users have blocked her), block rate (e.g., the rate at which other users block her), peer symmetry (e.g., percentage of her messages that are to other users that have her in their address book), message uniqueness (e.g., how unique her messages are from each other), peer uniqueness (e.g., how unique the addressees of her messages are), and message rate (e.g., the rate at which she sends messages). Periodically, metrics may be compared to corresponding thresholds. Depending on whether a threshold is crossed, and which threshold is crossed, she may be banned from using the application or placed on a watch list.

摘要： A system and methods are provided for establishing an authenticated and encrypted communication connection between two devices with at most two round-trip communications. During establishment of an initial authenticated, encrypted communication connection (or afterward), a first device (e.g., a server) provides the second device (e.g., a client) with a token (e.g., a challenge) that lives or persists beyond the current connection. After that connection is terminated and the second device initiates a new connection, it uses the token as part of the handshaking process to reduce the necessary round-trip communications to one.

摘要： Exemplary embodiments relate to techniques for improving the speed and rendering quality of an image (e.g., a JPEG), and are especially useful in an end-to-end encrypted environment. The image may be analyzed on the sending-client side and the image data is broken into multiple categories. In one embodiment, the image data is broken into four chunks, where each chunk could be rendered (in conjunction with previous chunks) to provide increasingly high levels of quality (e.g., a thumbnail chunk, a mid-quality chunk, a high-quality chunk, and a full-quality chunk). The image is uploaded to a blob store, and a message is sent to the receiving client with image information. At the recipient side, the JPEG image data is retrieved from the blob store and each chunk is rendered at progressively increasing levels of quality. Consequently, images are rendered faster, and the quality increases over time.

摘要： Exemplary embodiments are directed to a method for allowing a user at a first client device to provide access to restricted content on a content provider server to a user at a second client device without providing identifying information of the second client device or the user to the content provider. The content provider receives a request from a messaging app on a first client device for sharing of a content item with a second client device and generates a metadata block comprising at least a link to the content item. The metadata block is sent to the first client device and, in response, a public key of a private/public key pair of the second client device is received from the first client device. A request for the content item, is then received and contains a data item digitally signed using the private key of the private/public key pair of the second client device. The public key is then used to verify the digitally signed data item, thereby confirming the identity of the second client device. Thereafter, the requested content item is sent to the second client device.

摘要： Exemplary embodiments relate to techniques for asserting the authenticity of digital content being communicated among client devices of a communication or computer system by configuring the digital content with one or more sensor responsive elements. The sensor responsive element may be a visual interface that dynamically reacts or responds to sensor data generated by one or more sensors (such as a gyroscope sensor, a microphone, and a camera) of a receiving client device. If the sensor responsive element does not dynamically react or respond to movement data, image data, or sound data generated by the one or more sensors, the digital content may fail user inspection and may indicate to the recipient that the digital content is a fake or a counterfeit.
