Patent

CA 2260676

A system and method for performing an electronic transaction, including registration, audit and trusted recovery features. A transaction request message is received from a registered user that includes an unblinded validated certificate, and a blinded unvalidated certificate. If the unblended validated certificate is determined to be legitimate, then a transaction can be performed, and the blinded unvalidated certificate is validated to obtain a blinded, validated certificate that is sent to the user. An audit protocol can be used to further verify the legitimacy of the transaction request message, and a user can recover from a broken connection by replaying a protocol run.
