Description

FIELD OF THE INVENTION

[0002] The present invention relates to the field of electronic commerce. More specifically, the present invention relates to a method and apparatus for managing electronic commerce.

BACKGROUND OF THE INVENTION

[0003] Commerce on the Internet is attracting enormous financial interest from businesses large and small. The Internet is attractive to businesses because it enables them to reach a large audience and generate an impressive presence regardless of the size of the business. For many businesses, Internet commerce involves a business running a server system that takes credit card orders from a customer running a client system over the Internet. Sending and receiving sensitive information over the Internet raises many security issues. Some of these security issues include maintaining privacy by insuring that the information is inaccessible to anyone but the sender and receiver, and guaranteeing non-fabrication by insuring that the receiver is genuine.

[0004] Several software programs made available for client and server communication provide a Secure Socket Layer (SSL) protocol that employs a variety of standard encryption algorithms including the government and banking standard of Data Encryption Standard (DES) and several Rivest, Shamir, and Adleman (RSA) algorithms including RC4. SSL enables a client and server to exchange a secret number known as a Master_Key. After the Master_Key is shared, the client and server use the Master_Key to create a different set of keys called Session Keys. These keys are used with a specified cryptographic algorithm to encrypt and decrypt the contents of the communication session.

[0005] Even with the security measures provided through the SSL protocol in client and server software, communications between clients and servers are not unbreakable. Furthermore, regardless of how labor intensive the SSL protocol makes for an intruder to break an encrypted message between a client and server, the SSL protocol fails to provide a mechanism for insuring that the receiver is a genuine business.

SUMMARY

[0006] A method for managing electronic commerce according to a first embodiment of the present invention is disclosed. Consumer information is stored. A request made by the consumer to make a transaction and the consumer information is securely forwarded to a party in the transaction.

DETAILED DESCRIPTION

[0014] FIG. 1 is a block diagram illustrating a network in which an embodiment of the present invention is implemented. Block 110 represents a client system. Block 130 represents an electronic commerce system. Block 150 represents a server system. The client system 110 and the electronic commerce system 130 are coupled to a first transmission medium 120. The electronic commerce system 130 and the server system 150 are coupled to a second transmission medium 140.

[0015] According to an embodiment of the present invention, sending data on the first transmission medium 120 is insecure because the data may be monitored and read by someone other than a sender or receiver of the data. According to one embodiment of the present invention, the transmission medium may be the Internet. When a user of the client system 110 wishes to transmit sensitive information to another location such as the server system 150, the client system 110 sends the request to the electronic commerce system 130 over the first transmission medium 120 without actually sending the sensitive information. The electronic commerce system 130 stores consumer information including sensitive information such as credit information corresponding to the user. According to one embodiment of the present invention, the electronic commerce system 130 forwards the sensitive information to the server system 150 securely over the second transmission medium 140 upon receiving the request from the client system 110. In this embodiment, the second transmission medium 140 may be a direct telephone connection. According to a second embodiment of the present invention, the electronic commerce system 130 encrypts the sensitive information and forwards the encrypted sensitive information securely over the second transmission medium 140 upon receiving a request from the client system 110. In this embodiment, the second transmission medium 140 may be the Internet.

[0016] According to an embodiment of the present invention, the electronic commerce system 130 includes an information distributor that sends transactional information to the client system 110. According to an alternate embodiment of the present invention, the server system 150 includes an information distributor that sends the transactional information to the client system 110. In this embodiment, the electronic commerce system 130 verifies that the server system 150 is genuine before forwarding the sensitive information to the server system 150 as requested by the client system 110.

In alternative embodiments, hard-wire circuitry may be used in place of or in combination with software instructions to implement the present invention. Thus, the present invention is not limited to any specific combination of hardware circuitry and software.

[0030] FIG. 4 is a block diagram illustrating an embodiment of modules of an electronic commerce manager 400 operating in the electronic commerce system 130 (shown in FIG. 1), according to the present invention. The modules may be implemented by software, hardware, or a combination of both hardware and software. The electronic commerce manager 400 includes a storage medium 410. The storage medium 410 includes a first library 411 that stores information relating to consumers. The information in the first library 410 may include names, addresses, phone numbers, credit information, identifiers, or other information corresponding to the consumers. The storage medium 410 includes a second library 412 that stores information relating to businesses that practice electronic commerce. The information in the second library 410 may include the names, physical addresses, Internet addresses, phone and fax numbers, products sold, or other information relating to the businesses. According to an embodiment of the present invention, the second library 410 stores information relating to genuine businesses practicing electronic commerce that have been verified by managers of the electronic commerce manager 400. The verification may be achieved, for example, by checking the history of the business, whether any complaints have been filed against the business, or by referencing other information relating to the business.

[0031] A transaction manager 420 is coupled to the storage medium 410. As shown in FIG. 5, the transaction manager 420 includes a client interface 510, a transaction processor 520, a storage medium interface 530, and a server interface 540. The client interface 510 operates to receive a request to make a transaction from a client system 110 (shown in FIG. 1). The request may include an identifier (consumer identifier) corresponding to the user of the client system 110 who is a consumer, and a transaction identifier that identifies a business and a product sold by the business. The client interface 510 forwards the request to the transaction processor 520 coupled to the client interface 510.

[0032] The transaction processor 520 obtains information about the consumer making the request via the storage medium interface 530. The transaction processor 520 references the identifier received by the client system 110 (consumer identifier) with information in the first library 411 (shown in FIG. 4). The transaction processor 520 also verifies that the business the user wishes to engage in the transaction with is a genuine business via the storage medium interface 530. The transaction processor 520 references the transaction identifier received by the client system 110 with the information in the second library 412 (shown in FIG. 4). The transaction processor 520 forwards the information about the consumer and the transaction identifier to the server interface 540 coupled to the transaction processor 520.

[0033] The server interface 540 operates to securely forward the request to make a transaction and the information about the consumer to the server system 150 (shown in FIG. 1). According to one embodiment of the present invention, the server interface 540 is a telephone interface that operates to dial a direct telephone connection to the server system 150. A direct telephone connection provides a secure communication link where the risk of monitoring and reading of data traffic is reduced. According to a second embodiment of the present invention, the server interface 540 is an encryption unit and a network interface. The encryption unit encrypts the request and the information about the consumer before sending the request and the information over an Internet connection via the network interface. Encrypting the request and information reduces the chance that the request and information may be read by someone other than the sender or receiver. The present invention allows encryption to be performed on sensitive information and transmitted over the Internet without requiring a client system 110 to be configured with the necessary encryption hardware or software. The server interface 540 may securely forward the request to make a transaction and the information about the consumer to the server system 150 in real-time as the server interface 540 receives each request and information. In an alternate embodiment of the present invention, the server interface 540 may securely forward a plurality of requests and information using batch processing at a later time.

[0034] Referring back to FIG. 4, an information distributor 430 is coupled to the transaction manager 420. The information distributor 430 operates to distribute transactional information to the client system 110 (shown in FIG. 1). The transactional information may be, for example, information about a product or service that is for sale or other information. According to a first embodiment of the present invention, the information distributor 430 may be a network interface or a telephone interface that sends transactional information to the client system 110 over the Internet or over a direct phone connection. According to a second embodiment of the present invention where the electronic commerce system 130 is used for broadcasting broadcast data, the information distributor 430 may be a vertical blanking interval encoder, a cable link encoder, or a satellite link encoder that transmits transactional information over vertical blanking intervals, available cable bandwidth, or available satellite bandwidth during the transmission of broadcast data.

According to an embodiment of the present invention, business information is stored in a second library in the storage medium. The business information may include name, physical and Internet addresses, and product information corresponding to the business.

[0036] At step 602, transactional information is sent to the user. The transactional information may be, for example, information about a product that is for sale. According to an embodiment of the present invention, the transactional information is sent over the Internet to a user on a client system. It should be appreciated that the transactional information may be sent to the consumer via a direct phone connection, vertical blanking intervals of broadcast data, or via other communication mediums. According to an embodiment of the present invention, the transactional information is displayed to the consumer during the viewing of broadcast data by the user on a client system.

[0037] At step 603, a request to make a transaction is received from the consumer. According to an embodiment of the present invention, the user sends an identifier that identifies the consumer (consumer identifier) and a transaction identifier that identifies the transaction and a party of the transaction. According to an embodiment of the present invention, the identifier and the transaction identifier is sent by the consumer over the Internet.

[0038] At step 604, it is determined whether the party of the transaction is a genuine business. According to an embodiment of the present invention, the determination is made by referencing information in the second library of the storage medium that indicates whether the intended party of the transaction is a genuine business. If the party is a genuine business, control proceeds to step 606. If the party is not a genuine business, control proceeds to step 605.

[0039] At step 605, the request to make the transaction is terminated. According to an embodiment of the present invention, a message is sent to the user at the client system informing the consumer that the party is not a genuine business.

[0040] At step 606, the request made by the consumer to make a transaction and the consumer information corresponding to the consumer is securely forwarded to the party of the transaction. The request made by the user to make the transaction may be a request to purchase the product and the consumer information may be credit information belonging to the consumer. According to an embodiment of the present invention, the request and the consumer information is securely forwarded by transmitting the request and the consumer information over a direct phone connection. According to an alternate embodiment of the present invention, the request and the consumer information is encrypted and transmitted over the Internet.
