## Title
Method and apparatus for facilitating purchase transactions across a network

## Abstract

A local computer system that provides and records information to facilitate a purchase transaction across a network operates by first receiving a request for billing information relating to a purchase transaction from a remote computer system. The local system then retrieves the billing information from its local store, and sends the billing information to the remote system. After the remote system completes the purchase transaction, the local system receives a confirmation from the remote system. The local system then records this confirmation in its local store which enables a user of the local system to subsequently look up the confirmation information based on a purchase transaction identifier. Before the local system retrieves and sends the billing information, a user of the local system is asked to confirm if the billing information can be released to the remote system.

## Background
BACKGROUND
1. Field of the Invention
The present invention relates to electronic commerce. More specifically, the present invention relates to a method and an apparatus for providing information and recording information in order to facilitate a purchase transaction conducted across a network.
2. Related Art
The recent success of the electronic commerce over the Internet can largely be attributed to the ease with which consumers can make purchase transactions from the comfort and privacy of their homes at any hour of the day or night.
One of the problems in making such purchase transactions is that a consumer is required to input billing information, such as credit card information and a shipping address, in order to consummate the purchase transaction. The requirement to continually resubmit such information for each purchase transaction is an annoyance that can make the process of purchasing items across the Internet less attractive to a consumer.
In order to remedy this problem, some web sites store billing information for consumers that visit their web sites, so that the consumer does not have to re-enter the same billing information for subsequent purchase transactions on the web sites. Unfortunately, since the billing information is kept separately on each web site, the consumer must still re-enter the billing information in order to purchase items from new web sites.
What is needed is a method and an apparatus that provides billing information to a remote computer system in order to facilitate a purchase transaction from the remote computer system.
After a purchase transaction is complete, web sites often communicate confirmation information, such as a confirmation number, details of the purchase transaction and shipping information, to the consumer. This is typically accomplished by displaying the confirmation information on the consumer's browser. Unfortunately, in order to remember this confirmation information, the consumer typically scribbles the confirmation information on a scrap of paper, which can be easily lost. Confirmation information can additionally be sent to a consumer in an email message. However, this email message must be saved and cross-referenced with the purchase transaction, which involves extra work that can be annoying to the consumer.
Additionally, what is needed is a method and an apparatus that automatically receives and stores confirmation information related to the purchase transaction so that the confirmation information to be easily retrieved by the consumer.
SUMMARY
One embodiment of the present invention relates to a system that provides information and records information to facilitate a purchase transaction across a network. The system operates by receiving a request for billing information relating to a purchase transaction from a remote computer system. In response to the request, the system retrieves the billing information from a local store in the local computer system, and sends the billing information to the remote computer system. After the remote computer system completes the purchase transaction, the system receives confirmation information for the purchase transaction from the remote computer system. The system records this confirmation information in the local store in the local computer system. This enables a user of the local computer system to subsequently look up the confirmation information based on a purchase transaction identifier.
In one embodiment of the present invention, retrieving the billing information involves asking the user of the local computer system if the billing information can be released to the remote computer system. If the user confirms that the billing information can be released to the remote computer system, the local computer system sends the billing information to the remote computer system. In a variation on this embodiment, the system additionally asks the user of the local computer system for a password for the billing information, and uses this password to access the billing information from the local store.
In one embodiment of the present invention, the billing information includes credit card information for the purchase transaction, a billing address for the purchase transaction, and a shipping address for the purchase transaction.
In one embodiment of the present invention, the confirmation information includes a confirmation number for the purchase transaction, a list of the items involved in the purchase transaction, a total amount for the purchase transaction, a seller's name for the purchase transaction, a date of the purchase transaction, and shipping information related to the purchase transaction.
In one embodiment of the present invention, prior to receiving the request for the billing information, the system asks the user of the local computer system for the billing information, and records the billing information in the local store in the local computer system.
In one embodiment of the present invention, prior to receiving the request for the billing information, the system receives a request from the user of the local computer system to purchase at least one item from the remote computer system, and forwards the request to the remote computer system.

FIG. 3 illustrates a record containing confirmation information 108 in accordance with an embodiment of the present invention. In general, confirmation information 108 can include any type of information related to the purchase transaction that can be useful to a purchaser. For example, in the embodiment illustrated in FIG. 3, confirmation information 108 includes confirmation number 302, which can be used to reference the purchase transaction. Confirmation information 108 also includes details of the purchase transaction, including a list of the items purchased 304, and a total amount 306 (in a currency of choice) for the purchase transaction.
Confirmation information 108 also includes the date and time of the purchase transaction 308, as well as payment information 310 for the transaction. This payment information can include the credit card information from billing information 106, as well as any type of transaction identifiers or other information provided by the credit card company.
Confirmation information 108 also includes shipping information 312 which may specify the shipping company, the date the item was shipped, a scheduled delivery time, shipping costs, and a tracking number for the item.
Providing Billing Information and Recording Confirmation Information
FIG. 4 is a flow chart illustrating the process of automatically providing billing information and automatically recording confirmation information in accordance with an embodiment of the present invention.
The system starts by asking a user of a local computer system (client 102) for billing information (step 402). When the user provides the billing information, client 102 records it in storage device 104 (step 404). (Note that this process can take place during a preceding purchase transaction in which the user enters the billing information.)
While the user of client 102 is scanning through a web site, such as web site 118 on server 116, client 102 receives a request from the user to purchase an item from the remote computer system (server 116) (step 406). Browser 103 forwards the request to server 116 (step 408).
Next, client 102 receives a query from server 116 asking if client 102 is able to provide billing information 106 automatically (step 410). Client 102 responds affirmatively to this query (step 412).
Next, client 102 receives a request for billing information 106 from server 116 (step 414). In response to this request, client 102 asks the user of client 102 if billing information 106 can be released to server 116 (step 416). If the user says no, the system sends an error message to server 116 (step 419) and terminates the process.
If the user responds that the billing information 106 can be released, the system asks the user of client 102 for a password (or some other form of authentication) in order to access billing information 106 (step 420). The system uses the password (or other form of authentication) to retrieve billing information 106 from storage device 104 (step 422). This may involve using the password to decrypt billing information 106. Note that the steps of asking if the local computer system can provide billing information, and asking for a password are optional safeguards that are not used in some embodiments of the present invention.
Next, billing information 106 is sent to server 116 (step 424). This enables server 116 to process the purchase transaction (step 426).
After the purchase transaction is complete, client 102 receives confirmation information 108 from server 116 (step 428). Client 102 records confirmation information 108 in storage device 104 in a form that enables confirmation information 108 to be retrieved using a purchase transaction identifier (step 430). For example, confirmation information 108 can be stored so that it can be indexed by various attributes of the purchase transaction, such as the items purchased, the seller of the items, the date of the purchase, the confirmation number or the amount of the purchase. In one embodiment of the present invention, when the user of client 102 subsequently asks to view confirmation information, the user is presented with confirmation information from recent purchase transactions involving various web sites on network 110. This enables the user to select the confirmation information for a particular purchase transaction.
The foregoing descriptions of embodiments of the invention have been presented for purposes of illustration and description only. They are not intended to be exhaustive or to limit the present invention to the forms disclosed. Accordingly, many modifications and variations will be apparent to practitioners skilled in the art. Additionally, the above disclosure is not intended to limit the present invention. The scope of the present invention is defined by the appended claims.
