Abstract: An integrated communication interface is provided for composing and sending messages. The interface is multi-configurable to seamlessly switch between different communication methods, e.g., electronic mail, instant messaging, SMS, chat, voice, and the like, without loss of message content. The interface allows a user to begin composing a message to be sent using one communication method, such as electronic mail, and subsequently change the communication method and send the message via a second communication method, such as instant messaging. When the communication method is changed, the user interface may also change to include elements specific to a particular communication method. The integrated communication interface may display information about participants in the communication, such as the participants' presence, i.e., whether they are online and available for communication, and may automatically choose the best method of communication based on the preferences and online presence of the participants.

Abstract: A system and method for signing, sorting, and authenticating electronic documents using public key cryptography. The system comprises a document service computer cluster connected to user computers, document owner server computers, and registration computers via a network such as for example, the internet or the world wide web. Document owners and system users can store electronic documents in an encrypted database located on the document service computer cluster, or on a document safe connected to the document owner server. Users can sign documents by identifying the document to be signed and sending a signing request to the document service computer cluster. The document service computer cluster retrieves the user's private key, which is located securely in a database on the cluster, and signs the identified document. No dedicated signing software need be installed on the user computer prior to accessing the document service computer cluster.
