Abstract: A method to keep selected messages in a networked conversation thread includes receiving, from a first participant in a networked conversation, a selection of a first message to keep from a sequence of messages in the networked conversation. The method includes verifying that the networked conversation is slated for deletion at a selected time after the selection of the first message, storing the first message in a folder accessible to multiple participants in the networked conversation, and notifying a second participant authoring the first message that the first message has been stored in the folder and is accessible to the participants in the networked conversation.

Abstract: A messaging system receives a message including a recipient ID and a message body, the message body containing one or more customizable fields. The messaging system receives a user preference model based on the recipient ID. The user preference model identifies message elements and content preferred by the recipient of the message. Based on the user preference model, the messaging system modifies the customizable fields in the message body, generating a modified message. The modified message is transmitted to a client device associated with the recipient ID for presentation to the recipient.

Abstract: Exemplary embodiments relate to techniques for transmitting ephemeral content messages. A sending client may establish an end-to-end encrypted session with possible recipients of the message, using a first decryption key during initial session setup. The client may send an ephemeral content message, including encrypted content and a second key, to the recipients through a server. The server may be unable to retrieve the encrypted content due to a lack of the second key. The server may filter a list of intended recipients, and may forward the ephemeral content message to the recipients on the filtered list. The recipients may retrieve the second key from the message, and use the first and second keys to decrypt the encrypted content. The sending client may change the second key each time the recipient list changes from the perspective of the sending client, as determined at the time the ephemeral content message is transmitted.

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.

Abstract: A messaging server establishes a video chat between first and second endpoints through a first and second router. In parallel, the messaging server transmits instructions to the first endpoint causing the first endpoint to transmit packets through a plurality of ports of the first router to a designated port of the second router. In addition, the messaging server transmits instructions to the second endpoint causing the second endpoint to transmit packets through a plurality of ports of the second router to a corresponding plurality of ports of the first router. A P2P connection is established between the first and second endpoints in response to a first port of the plurality of ports of the first router receiving a data packet from the designated port of the second router. The video chat is seamlessly transferred from the connection established through the messaging server to the established P2P connection.

Abstract: Exemplary embodiments relate to techniques for anonymizing information in an end-to-end (E2E) encrypted environment; the information may include, for example, statistical data about unique page/message views, view counts, view time, what users selected on the message or page, etc. Exemplary embodiments may prevent an E2E system server from being able to identify which user is associated with which record. Various examples are described, including an embodiment in which an originating client generates the data, encrypts it, and sends it to a random contact. The contact decrypts the data, re-encrypts it, and sends it to another random contact. The procedure continues for a set amount of time or for a set number of hops. Other embodiments relate to wrapping the data in various layers of encryption and sending the data to clients in a chain. The encrypted layers prevent clients along the chain from being able to view the anonymized data.

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 second client device receives, in a messaging app, a message from the first client device comprising a link to a content item at a content provider and an identifier of a private/public key pair on the second client device. Second client device displays the link in the user interface of the messaging app and receives a user selection of the link. Second client device generates generating a digital signature for the link using the private key of the private/public key pair and sends the link and the digital signature to the content provider. The content item is then received from the content provider and displayed on the second client device.

Abstract: The present disclosure relates to systems, non-transitory computer-readable media, and methods for dynamically controlling ephemeral messaging threads and ephemeral message duration settings across computing devices while improving security by maintaining end-to-end encryption. In particular, in one or more embodiments, the disclosed systems can transmit encrypted ephemeral messages, including ephemeral message duration settings and ephemeral setting timestamps. The disclosed systems can decrypt received messages on receiving client devices and dynamically apply ephemeral message duration settings to different message threads. For example, the disclosed systems can modify existing duration settings at a receiving client device to match a received ephemeral message duration setting based on determining that the received ephemeral setting timestamp predates an existing setting timestamp.

Abstract: This disclosure covers methods, computer-readable media, and systems that animate a digital graphic associated with a video or other visual media item based on a detected dynamic attribute. In particular, the disclosed methods, computer-readable media, and systems detect sensor data from a client device or a motion of an object within a video or other visual media item. Based on the detected sensor data or motion of an object within a visual media item, the methods, computer-readable media, and systems overlay and animate an emoji or other digital graphic selected by a user on a video or other visual media item.

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.

Other embodiments are described and claimed.

Abstract: Exemplary embodiments relate to methods and systems for transferring a user's messaging history from one device to another. A user's primary device, storing the official truth of the user's messaging history, establishes an end-to-end encrypted session with a new device, using a first decryption key during initial session setup. The primary device may conglomerate all or a portion of the messages comprising the user's messaging history into a data blob which is encrypted and sent to a blob store. An E2E encrypted message is sent from the primary device to the new device, via an intermediate server. The E2E encrypted message includes a second key for decrypting the data blob and a pointer to the location of data blob on the blob store. The new device retrieves the data blob from the blob store and decrypts the data blob using the second key to extract plaintext versions of the user's messages and adds the messages to the messaging application on the new device.
