System and method for secure electronic communication in a partially keyless environment

This present invention provides users with secure transparent electronic communication, allowing them to send and receive encrypted and/or signed messages with little or no user involvement. In various embodiments, the present invention provides a user with e-mail security via automated hierarchical techniques for transparently sending and receiving secure messages, and lowers the burden on administrators. Such a system can also manage cryptographic keys and certificates for the users, and creates such keys and certificates for the users when necessary. A server according to the present invention can intercept unsecured messages from a user, automatically transform those messages into secured messages, and transmit those secure messages to the intended recipients. The server can also automatically transform messages after the recipient sends a digital identity to the server and downloads the software necessary for transforming the secured messages back into readable messages (i.e., from ciphertext into plaintext). The server can further intercept an unsecured message from a user, search for a digital identity of the intended recipient, secure the unsecured message upon finding such a digital identity, and transparently send the secured message to the intended recipient.

Automatically setting an avoidance threshold and adjusting a chat presence based on user avoidance of chat sessions

InactiveUS20070061405A1Improved automated presence state adjustmentEasy to adjustMultiple digital computer combinationsData switching networksClient-sideClient system
A chat presence state adjustment indicating an availability of a particular user to participate in new chat sessions is automatically performed in a computer system. The computer system, which is in communication with a network, includes at least one of a chat server that facilitates chat communications between multiple client systems logged onto by multiple users and a particular client system logged onto by a particular user from among the multiple user. The computer system includes an avoidance controller that first detects a selection of chat sessions avoided by the particular user over a period of time from among the total chat session directed to the particular user over the period of time. In particular, the avoidance controller detects that the user avoids each of the selection of chat sessions through at least one separate type of avoidance activity. Next, the avoidance controller automatically sets at least one avoidance threshold based on at least one threshold characteristic of the selection of chat sessions avoided by the particular user. The avoidance threshold is set so that when future avoidance activity by the particular user exceeds the avoidance threshold, avoidance controller will automatically adjust the chat presence state of the particular user to indicate lack of availability of the particular user to participate in a new chat session.
