Abstract: Parties involved in a transaction in an E-marketplace can “pre-qualify” an entity that can transact business in the E-marketplace. The entity is a “persona” that is able to satisfy the needs of another party in the E-marketplace; none of the parties making up the entity can alone satisfy these needs, but together they are able to. The attributes of the parties making up the entity are verified by a third party (such as the E-marketplace) and a single attribute certificate, identifying the combined attributes of the persona, is made available to users of the E-marketplace.

Abstract: Parties involved in a particular transaction in an E-marketplace each identify and submit to the E-marketplace relevant characteristics related to that transaction. The identification of the party is not revealed with this submission. To achieve this, an attribute certificate is created which contains attributes related to a buyer or seller's potential participation in a transaction. The attributes that are selected pertain to specifics of the transaction and not to the certificate holder. Each of the attributes are verified by a trusted authority (e.g., the E-marketplace acting as an intermediary for the transaction) so that when the attribute certificate is supplied to a party, the party is assured that the information it contains is accurate. In this manner, parties to a negotiation in a particular transaction are able to know immediately and with a high level of assurance that certain critical elements to the proposed transaction are met (or are capable of being met).

Abstract: Parties involved in a transaction in an E-marketplace identify characteristics of a transaction that they are willing to accept and/or that they can provide. To do this, an attribute certificate is created for each party that contains the attributes of a buyer, seller, or third-party participant who will be transacting business in the particular E-marketplace. The attributes pertain to specifics of the transaction. The party submitting the attribute also identifies alternative conditions which, if they exist would be acceptable for conducting the transaction. Once these criteria, in the form of the attribute certificates, are received by the E-marketplace, the E-marketplace verifies the attributes. A server in the E-marketplace is configured to determine various combinations of participants that can match the deal criteria. In this manner, the E-marketplace “choreographs” the transaction to meet the needs of all.

Abstract: A method, system, and computer-readable code for delegating authority and authentication from a client to a server in order that the server can establish a secure connection (using SSL or an analogous security protocol) to a back-end application on behalf of the client. This enables the true client's identity to be known to the application on the end-tier server. The proposed solution provides several alternative techniques, whereby the client establishes a secure session with a middle-tier server (MTS), and then delegates authority and authentication to the MTS in order that the MTS can establish a second SSL session to the ETS on behalf of this client.
