`
`ABSTRACT
`
`A multi—component system for linking a user to a product or
`service provider includes a user processing device, a storage
`device, and a provider device. The storage device stores
`provider-specific application software, user-specific data,
`and a file management program. The storage device and the
`processing device are coupled to each other to form a user
`device which communicates with the provider device. Under
`direction of the file management program, the processing
`device carries out a recognition methodology which deter—
`mines whether the processing device and the storage device
`are authorized to operate with each other. This aspect of the
`system makes it possible to render the storage device
`operable only with a specific user processing device,
`referred to as the principal processing device. This, in turn,
`reduces the possibility of fraud since the storage device
`cannot be used without the principal processing device.
`Once it is determined that the processing and storage devices
`are authorized to interact with each other, the processing
`device executes the provider-specific application software to
`exchange information with the provider device. Together,
`the user and provider devices implement unique recognition
`and comprehension methodologies to ensure that the parties
`are authorized to communicate with each other and to ensure
`that the information exchanged cannot be understood by
`third parties. Overall, the system provides a highly secure
`mechanism for transfening information from one party to
`another.

`PERSONAL ACCESS MANAGEMENT
`SYSTEM
`
`FIELD OF THE INVENTION
`
`This invention relates generally to transactional,
`communication, and authorization systems, and more par-
`ticularly to a multi—component system which implements
`unique recognition and comprehension methodologies to
`verify party identities and to ensure session security.
`
`BACKGROUND OF THE INVENTION
`
`For a number of years now, tremendous efforts have been
`devoted to devising systems for linking consumers with
`product and service providers which would allow the con-
`sumers to communicate and to transact with the providers
`from remote locations, such as from their homes. Such
`etforts have produced some systems which have received a
`small degree of acceptance. Examples include home shop-
`ping networks (such as QVC), home entertainment systems
`(such as DirecTV), remote stock transaction systems (such
`as Reuters), and automatic teller machine (ATM) systems.
`While these remote systems have gained some acceptance,
`there still is, for the most part, an absence of a generally and
`widely accepted system for conducting business from a
`remote site.
`
`The failure of the presently existing systems can be
`attributed to a number of different factors. One possible
`factor is cost, both in terms of the providers’ cost and the
`cost to the consumers. Currently, consumers are typically
`linked to providers not directly but through aggregators. The
`presence of an aggregator adds a middleman to the business
`process which i
