See full text

Collaboratively editing a document in a system of sharee clients includes creating a document change, generating a document token for encrypting the document change, encrypting the document change with the document token, making the encrypted document change available to the other sharee clients, and generating a plurality of copies of the sharee document token. Each sharee document token is encrypted with a respective sharee's public key. Each encrypted sharee document token is distributed to respective sharee clients. Each sharee client is configured to: decrypt a sharee document token using a respective private key, decrypt the encrypted document change using the share document token, and consolidate the document change into a document.
