Abstract: An information stream management network server is disclosed that enables distributing articles to a destination in the network at times and in forms that are specified by a user, while also enabling accessing and receiving the articles from sources in the network at times and in forms that are independent of the user. The network server handles both information pull articles and information push articles. The information push articles use declarative addressing to specified groups of users, thereby masking recipient endpoint identities and delivery preferences from sources and enabling broadcast communication to members of such a group.

Abstract: Secure electronic transactions using a trusted intermediary with non-repudiation of receipt and contents of message. A system of, and method for, securely transmitting a package from a sender to a recipient, via an intermediary, are described, as is a novel data arrangement, stored in a computer-readable medium. A sender encrypts the message to form an encrypted inner envelope. A waybill is formed that among other things identifies the recipient as the destination and includes information indicating various levels of services desired, e.g., electronic notarization. The waybill and inner envelope are used to form an encrypted outer envelope that is addressed to a trusted intermediary. The intermediary receives the package and decrypts the outer envelope. It is unable to decrypt the inner envelope, due to the keys employed during encryption. The service information is processed, and the package is used to form a second package addressed to the recipient.

A system for, and method of, securely transmitting a package from a sender to a recipient, via an intermediary, are described, along with a novel data arrangement, stored in a computer-readable medium. A sender encrypts the message to form an encrypted inner envelope. A waybill is formed that among other things identifies the recipient as the destination and includes information indicating various levels of services desired, e.g., electronic notarization.

It is unable to decrypt the inner envelope, due to the keys employed during encryption. The service information is processed, and the package is used to form a second package addressed to the recipient. The recipient decrypts the package and confirms receipt thereof, using a digest of the message.
