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

A method for receiving messages from a web service server on 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;
• sending a first login including a first user ID by the current user to the web service server;
• receiving undelivered messages of the current user and encrypted undelivered messages of the offline user from the web service server in response to sending the first login including the first user ID to the web service server;
• storing received encrypted messages of the offline user in a memory of the computing device;
• sending to the web service server a second login including a second user ID and identifying a second user as a new current user of the computing device;
• receiving an encrypted decryption key from the web service server in response to sending the second login including the second user ID;
• decrypting the encrypted decryption key using a shared key known to one of the new current user and the computing device;
• decrypting the new current user's encrypted messages using the decrypted decryption key;
• and
• displaying the decrypted messages on an electronic display of the computing device.

A system, comprising:

• a server comprising a server processor;
• and
• a computing device configured to communicate with the server,
• wherein the server processor is configured with server-executable instructions to perform operations comprising:

• receiving 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, and

• displaying the received messages of the current user on the electronic display via a foreground process;
• and
• storing the received messages of the offline user in the memory via a background process.

A computing device, comprising:
