This disclosure relates generally to apparatus, methods, and computer readable media for composing communications for computing devices across multiple formats and multiple protocols. More particularly, but not by way of limitation, this disclosure relates to apparatus, methods, and computer readable media to permit computing devices, e.g., smartphones, tablets, laptops, and the like, to send communications in a number of pre-determined and/or ‘determined-on-the-fly’ optimal communications formats and/or protocols. Determinations of optimal delivery methods may be intelligently based on the sender individually or the relationship with the sender in the context of a group of recipients—including the format of the incoming communication, the preferred format of the recipient and/or sender, and an optimal format for a given communication message. The techniques disclosed herein allow communications systems to become ‘message-centric’ or ‘people-centric,’ as opposed to ‘protocol-centric,’ eventually allowing consideration of message protocol to fall away entirely for the sender of the communication.

A technique for message history display includes combining message histories for multiple different messaging services. A system constructed according to the technique may include, for example, a message history database; a history aggregation engine that aggregates message logs for storage in the message history database; and a history provisioning engine that provides an aggregated message log associated with the user from the message history database to a requesting device. A method according to the technique may include, for example, identifying a device in association with a user profile; providing an online platform that receives messages from and sends messages to the device; and creating an aggregated log from messages sent to and from the device.

Systems and methods for providing independent situational awareness messages are provided. The method includes receiving, by a rendering engine, a request for information from an input interface. The rendering engine queries at least one data store in response to the request. The rendering engine obtains public content data and private content data from the data store. The rendering engine transmits the public content data over a public output interface. The rendering engine transmits the private content data over a private output interface.

This disclosure relates to personalized and dynamic server-side searching techniques for encrypted data. Current so-called ‘zero-knowledge’ privacy systems (i.e., systems where the server has ‘zero-knowledge’ about the client data that it is storing) utilize servers that hold encrypted data without the decryption keys necessary to decrypt, index, and/or re-encrypt the data. As such, the servers are not able to perform any kind of meaningful server-side search process, as it would require access to the underlying decrypted data. Therefore, such prior art ‘zero-knowledge’ privacy systems provide a limited ability for a user to search through a large dataset of encrypted documents to find critical information. Disclosed herein are communications systems that offer the increased security and privacy of client-side encryption to content owners, while still providing for highly relevant server-side search-based results via the use of content correlation, predictive analysis, and augmented semantic tag clouds for the indexing of encrypted data.

A communication device identifies presence of a user in proximity to the device. The communication device includes: at least one input device that captures biometric data associated with at least one user; a network interface device that connects the communication device to at least one second device via an external network; and a processor communicatively coupled to the other devices/components. The processor executes a messaging module to: receive biometric data from the at least one input device; determine if the biometric data matches reference biometric data associated with the at least one user. The processor further, in response to determining that the biometric data matches the reference biometric data associated with the at least one user: generates user presence data, the user presence data indicating that the at least one user is within a vicinity of the first communication device; and transmits the user presence data to the second device.

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. Multiple data blobs may be sent from the primary device to the new device until all or a desired subset of the user's messaging history is present on the new device.

A first request to create a content resource from a client device associated with a client account of the SaaS platform is received via a first application programming interface (API) call. The first request specifies message content for messages to be sent via multiple communication channels, identifies the message content in a first format, and format is translatable to multiple second formats that each correspond to one of the communication channels. The content resource received via the first API call is stored, at the SaaS platform. An identifier of the content resource is provided to the client device associated with the client account via a first API response.
