Abstract: The invention is directed to techniques to secure interactions between entities communicating on a computer network. In general, techniques are described in which a first entity provides assurances to a second entity that an agent interacting with the second entity is interacting with the second entity on behalf of the first entity. Specifically, the techniques provide the second entity with information tending to indicate that the first entity authorized the agent to perform the interaction with the second entity pursuant to some prior agreement between the two entities. The techniques employ authentication systems and encryption to ensure the security of the interaction.

Abstract: The invention is directed to techniques of facilitating document transmission from one entity through an electronic communications network. An entity may be a legally recognized person such as a corporation, partnership, organization, government, individual, and the like. As a legally recognized person, an entity may act as a principal with respect to one or more authorized agents. Furthermore, as a legal person, an entity may authorize one or more of its agents to use fax transmission equipment such as the fax certification system described herein. The techniques of this invention assure a second entity that a first entity has indeed authorized its agent to send a document from a fax station under the controls of the first entity.
