Abstract: A method for providing privacy in online transactions. The method can include receiving, at a service provider system, a purchase request from a client, the purchase request including banking information, and the banking information being encrypted with a third party public key such that the service provider system cannot decrypt the encrypted banking information. The encrypted banking information can be transmitted to a bank system, such that the banking information cannot be used to identify the identity of the client. The method can also include receiving an authorization message if the client's purchase request is authorized.
