<p>A web browser inserts a user-neutral identifier into its webpage requests. A proxy server creates records of the webpage requests, and further processes these records to create and update profiles for the corresponding user-neutral identifiers. Upon receiving a webpage request including payment transaction information, which is redirected from a payment provider, the proxy server determines whether payment should be processed by analyzing one or more data elements in the request in view of the corresponding profile. Upon determining that the payment should be processed, the proxy server forwards the payment transaction information to a payment provider. By indexing the profiles according to user-neutral identifiers, rather than specific user information, user privacy can be maintained while still being able to authenticate whether a payment transaction is legitimate.</p> |
