Patent attributes
A system and method protects users against theft of personally identifiable information during both online and offline purchase transactions, registration transactions and identity authentication transactions. The system initially obtains a user's personally identifiable information as storable computer data, establishes an anonymous email address on behalf of the subscribing user, provides the anonymous email address to an email recipient when the subscribing user sends an email to the recipient, receives email communications from the recipient at the anonymous email address, stores the routing information from the email communications, scrubs the email communications for electronic viruses, forwards the email communications received from the recipient at the anonymous email address to the subscribing user, and forwards email communications to the recipient that are sent from the subscribing user to the anonymous email address by matching the stored routing information without ever revealing the subscribing user's real email address to the recipient.
