Abstract: 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.

Abstract: A system and method for automatically verifying a telephone number proffered by a user of an application. During registration or installation of the application, client software is installed on the user's mobile device (e.g., a smart phone, a tablet computer). One of a pool of telephone numbers for outgoing calls is selected, and a call is initiated to the proffered number by the system. The software executing on the user's device detects the incoming call, extracts caller identification data (i.e., the originating telephone number), formats a data communication (e.g., an http request) to include the data, and sends it to the system. The system receives the data communication and compares the data with the originating number. If they match, the user's telephone number is verified. The outgoing call from the system may be canceled before it rings at the device if the data communication is received in time.

Abstract: A method, apparatus and computer program product is provided for processing the status of phone devices having a phone number. A synthetic communication server receives updated status of a target phone device referencing a normalized phone number that specifically identifies the target phone device on a synthetic communication network. Accordingly, the server stores the updated status of the target phone device in a status area referenced by the normalized phone number. The server identifies a subset of phone devices from phone devices on the synthetic communication network interested in the status of the target phone device. For each of the phone devices in the subset, the server pushes the updated status of the target phone device to each phone device in the subset.Yet another aspect of the invention concerns monitoring status of the phone devices in a status list of normalized phone numbers on a phone device. The phone device monitors other phone devices and also provides individual status. Accordingly, the method and system sends the status list and updated status of the phone device that includes a normalized phone number identifying the phone device on the synthetic communication network. Subsequently, the method and system receives the status updates of the one or more other phone devices in the status list. The status updates received are also referenced using the corresponding normalized phone numbers for each of the other phone devices. These status updates of the one or more other phone devices are processed by the method and system and then displayed in a display area of the phone device.

Abstract: Aspects of the present invention provide a method and system of registering a phone device on a synthetic communication network. One implementation receives a request to connect the phone device to a synthetic communication network that transmits messages over a data network using one or more phone numbers from a voice network. Aspects of the present invention initially obtain a phone number and a corresponding country code presumed associated with the phone device to be used for communications over the synthetic communication network. Based on the country code, the phone number is normalized to a standard format that distinguishes the resulting normalized phone number from international phone numbers using the synthetic communication network. Before the phone device is registered, aspects of the present invention verify an association between the normalized phone number and the phone device by sending a verification message addressed to the phone device that loops back and returns to the phone device. If the phone device confirms the verification as authentic then an authorization from the synthetic communication network allows the phone device to communicate over the synthetic communication network.

Abstract: A method, apparatus and computer program product is provided for verifying an association between a phone number provisioned by a voice network and a phone device. The verification is useful on a synthetic communication network that reuses the phone number to transmit text and other media types over a data network such as the Internet between phone devices registered on the synthesized network. One implementation receives a request to add a phone device previously registered with a voice network to the synthesized communication network. With respect to the synthesized network, the phone number is presumed to be unconfirmed even though it may have been previously provisioned from the voice network. Implementations of the invention attempt to transmit a verification message addressed to the phone device through a data channel within the voice network. If the phone number is in fact associated with the phone device then the verification message returns back to the phone device over the data channel on the voice network. If the verification message is received by the phone device, the phone number is confirmed as associated with the phone device. Once the phone number is confirmed, the synthetic network authorizes communication between the phone device and other phone devices registered on the synthetic communication network.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Exemplary embodiments relate to techniques for improving the speed and rendering quality of an image (e.g., a JPEG), particularly in an end-to-end encrypted environment. The image may be analyzed on the sending-client side and the image data may be broken into a thumbnail and a full-quality image, where the full-quality image data relies on the thumbnail data to render a high-quality image. 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 the thumbnail is first rendered. Subsequently, as the remainder of the image data is received at the receiving client, the image is updated. Consequently, images are rendered faster, and the thumbnail can be automatically downloaded so that a user can determine if they wish to download the full image.
