Abstract
The invention provides a method for transmission of sensitive information via an untrusted party. The sensitive information is held by a trusted computer and is transmitted via an untrusted computer to a recipient computer. Before transmission, the trusted computer encrypts the sensitive information using an encryption key that is associated with the recipient computer. The untrusted computer does not have access to a corresponding decryption key and is therefore unable to decrypt the sensitive information. The recipient computer is able to decrypt the encrypted sensitive information using a decryption key that it has access to and is thus able to gain access to the sensitive information without further communication with the trusted computer. This method has utility in payment transactions, particularly e-commerce transactions.
