Abstract: A method of sharing collaborative data between registered users in an online collaboration system. The collaboration system has a server and one or more electronic user devices that are capable of data communication with the server over a data network. Each registered user is allocated a unique asymmetric key pair comprising a user public key and a user private key for encryption and decryption of shared data content. The server is able to modify uploaded encrypted data content to enable access by multiple authorised users, and is able to convert uploaded data content into alternative formats, typically to enable web-browser viewing.
