Optimizing offline message (network history) delivery for users accessing an application from a single device

摘要

Devices, systems and methods for sending messages from a web service server to a computing device shared by a current user and another offline user while maintaining privacy for the other offline user's messages and decreasing bandwidth requirements for transmission of messages may include registering the user and the offline user of the computing device with the web service server, receiving at the web service server from the computing device a login by a first user, wherein the first user is determined to be the current user, checking a database for undelivered messages for the at least one offline user who is not currently accessing the web service server, wherein any user who is not a current user is determined to be an offline user, encrypting each offline user's undelivered messages, sending the undelivered messages to the computing device, and storing offline user encrypted undelivered messages in the computing device.

主权项

1. A method of sending messages from a web service server to a computing device shared by a current user and an offline user while maintaining privacy for the offline user's messages and decreasing bandwidth requirements for transmission of messages, comprising:
registering the current user and the offline user with the web service server; receiving at the web service server from the computing device a first user login including a first user ID and identifying a first user as the current user of the computing device; querying a database to identify undelivered messages of the current user and to identify undelivered messages of the offline user in response to identifying the first user as the current user of the computing device; sending the identified undelivered messages of the current user to the computing device; and encrypting the identified undelivered messages of the offline user and sending the encrypted undelivered messages of the offline user to the computing device.
