International Classification:

H04L 1200

US Classification:

705 40, 705 26, 705 27, 705 77, 709203, 709230, 709245, 709250, 709249

Abstract:

An architecture is disclosed allowing a server to communicate bidirectionally with a gateway over a first communication link, over which service requests are initiated by the server. In response to a transaction received from a host legacy system at the gateway, the gateway parses one or more transaction response values from the host message, maps the one or more transaction response values to a canonical response code, and stores the canonical response code in a transaction log. According to a broad aspect of a preferred embodiment of the invention, communication networks that employ transactions between applications must effectively manage transactions that flow over the network. In addition, networking systems must also detect counterfeit transactions, especially, when the networking systems are utilized for financial transactions. An active, on-line database is utilized as a transaction log to track original requests, valid retrys and detect fradulant transactions. The transaction log serves as a memory cache where the received host response is returned to a valid retry transaction should the original response fail to reach a server because of a communications problem.

International Classification:

H04L 900

US Classification:

380 24

Abstract:

Secure transmission of data is provided between a plurality of computer systems over a public communication system, such as the Internet. Secure transmission of data is provided from a customer computer system to a merchant computer system, and for the further secure transmission of payment information regarding a payment instrument from the merchant computer system to a payment gateway computer system. The payment gateway system evaluates the payment information and returns a level of authorization of credit via a secure transmission to the merchant which is communicated to the customer by the merchant. The merchant can then determine whether to accept the payment instrument tendered or deny credit and require another payment instrument. An architecture that provides support for additional message types that are not SET compliant is provided by a preferred embodiment of the invention. A server communicating bidirectionally with a gateway is disclosed.

International Classification:

H04L 900

US Classification:

380 25

Abstract:

An architecture for processing a plurality of transactions from a single point of initiation is disclosed. The initiating computer selects a terminal identification token, and associates the token with a transaction request, thereby ensuring the association of the transaction with a unique terminal identification despite being originated by the same terminal. The tokens are obtained from a token table, which contains a row for each token defined to the system. The table includes a column for the token, a column that identifies a system with which the token may be used, and a column that identifies a date and time field indicating when a particular token was selected for use. A null value in the date-time field indicates that the token for that row is not in use. A query operation selects a token with a null date-time value, and a set operation sets the date-time value to the then-current time to mark it in use. At the conclusion of the transaction, a set operation sets the date-time value to null, enabling the token to be reused for another non-concurrent transaction.

US Classification:

705 79

Abstract:

A server communicates bidirectionally with a gateway over a first communication link, over which service requests flow to the server for one or more merchants and/or consumers. Service requests are associated with a particular merchant based on storefront visited by a consumer or credentials presented by a merchant. Service requests result in merchant specific transactions that are transmitted to the gateway for further processing on existing host applications.

Abstract:

A smart document includes enhanced metadata and document content. The enhanced metadata may store an embedded database for recording and tracking a document history and rules. The smart document may be hashed to generate a unique document identifier. The unique document identifier is stored in a distributed ledge and paired with exposed metadata for enforcing access rules for the smart document.

Abstract:

A flavor accelerator system to speed imparting flavor into a foodstuff within a container comprising a hollow needle, where the hollow need extends between a tip and an end; a hose attached to the end of the hollow needle, where the hose is attached to a carbon dioxide canister at an opposite end from the hollow needle; and an injection lid on the container, where the injection lid seals the container, and where the injection lid includes an inlet port within the injection lid; and an injection nipple at a top of the injection port, where the injection nipple receives the hollow needle; wherein the hollow needle injects carbon dioxide into the container through the inlet port within the injection lid to accelerate the speed at which the foodstuff is flavored.
