ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates generally to a system and method for limiting access to confidential information during an e-commerce transaction and more particularly to the use of cross-media to confirm an e-commerce transaction.
One of the greatest deterrents to widespread use of electronic commerce involves consumers' lack of confidence in current techniques used to secure confidential information. Although encryption techniques have been used to prevent third parties from discovering a customer's confidential information, many customers remain reluctant to provide a company with confidential information over the Internet. In particular, some customers are wary that the company will misuse the information by making fraudulent purchases or will sell the information to another company. These wary consumers recognize that in electronic transactions, confidential information such as credit cards numbers, social security numbers, telephone numbers and addresses, can be copied and distributed many times and across several companies with little effort. Accordingly, transactions over the Internet have been primarily limited to reputable companies, making e-commerce difficult for newer companies.
SUMMARY OF THE INVENTION
A method consistent with the present invention for effectuating a secure transaction between a user and a party represented by a web-site comprises several steps. Initially, user profile data, including unique user identification codes, as well as instructions and user data corresponding to the identification codes, are stored in a database. The profile server receives a user identification code and retrieves the instructions corresponding to the user identification code. Thereafter, the profile server performs a confirmation operation in accordance with the retrieved instructions.
A system consistent with the present invention for providing a secure transaction between a user and a party represented by a web-site comprises a profile server, a web-site server and a client. The profile server stores a user profile tag which includes a unique user identification code, user data, and instructions. When a user visits a web-site, the web-site server automatically receives the user's identification code. In requesting access to user data or completion of a transaction, the web-site server provides the user identification code to the profile server. In response, the profile server performs a confirmation operation in accordance with the instructions stored in the user profile tag. Until successful completion of the confirmation process, the server denies the party access to the user data and does not complete the transaction.
Both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.
