Abstract: One embodiment of the present invention provides a system that facilitates transferring data between a data device and a data terminal across a network. The system initializes itself by establishing connections between the controller, multiplexer, and data device. The system operates by receiving a request at a multiplexer from a controller to transfer data from the data device to the data terminal. The multiplexer forwards this request to the data device that has the requested data. The multiplexer then receives a set of parameters from the data device, including the location of the outgoing data within the data device. The multiplexer moves the data from the data device into an outgoing data stream, thereby removing the necessity of first copying the data into the controller.

Abstract: The present invention comprises a method and apparatus for authenticating data related to on-line transactions. The invention utilizes a user-customized certification indicator that informs a user as to the success or failure of one or more authentication and/or security protocols implemented on a user communications access device such as a personal computer, a personal digital assistant ("PDA"), an enhanced function telephone, etc. In one or more embodiments, one of the components of the indicator is user defined, and locally stored, reducing the likelihood of interception and counterfeiting. In one or more embodiments, the indicator components include a centrally provided graphic element and a user defined text overlay. When a user initiates an electronic transaction, a background validation process is initiated that implements procedures for determining the authenticity of data related to the transaction, such as the identity of a transaction party.
