Abstract: 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.

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 relate to techniques for sending ephemeral content messages via a communications service. An interface may be presented to allow a user to initially access ephemeral content functionality and select content for inclusion in the ephemeral content message. The interface may present a streamlined set of use cases without regard to the manner in which the content was initially captured. Different types of content may be used as ephemeral content, including images, videos, weather reports, news stories, text, audio recordings, location tags, etc. The ephemeral content may be sent through the communications service as an end-to-end encrypted message. When a user replies to an ephemeral content message, the reply may trigger a one-to-one conversation between the originating user and the replying user. Alternatively, an ephemeral content message may be initially sent to a selected group, and replies may be sent back to the entire group.

Abstract: Exemplary embodiments relate to techniques for displaying and interacting with ephemeral content messages in a communication service. Ephemeral content, transmitted as a message in order to preserve end-to-end encryption, may be tagged with an identifier designating the message as an ephemeral content message. A receiving client may recognize the flag and display the content of the message as ephemeral content. The update may include a link to the content that expires under certain conditions. While the link is active, the link may be selected to enter a full-screen presentation of the ephemeral content. Different media types may be associated with different types of full-screen presentations. Displayed ephemeral content from different users may be ranked based on an interest score and displayed in the ranked order. Ephemeral content may be displayed in a user interface on separate tabs.

Abstract: A system, apparatus, and methods are provided for facilitating payment for a third party's use of an application by a current user. The current user, or payor, initiates the process within the application by selecting one or more recipients. The system that hosts the application then determines which of the third parties are eligible. A target recipient may be ineligible because her application subscription never expires, because it doesn't expire within a threshold period of time, or for some other reason. The system identifies the target recipients that are eligible, and the payor may configure the gift payment (e.g., by choosing a duration of the subscription). The payor then chooses a method of electronic payment and, depending on the method selected, may redeem a coupon with the application host system, or the process may complete automatically. The payor and/or the recipient(s) may be notified of successful activation of the subscription(s).
