DEVICE-PAIRING BY READING AN ADDRESS PROVIDED IN DEVICE-READABLE FORM

A system is described for allowing a user, operating a trusted device, to remotely log into a server via a potentially untrustworthy client. A first secure connection is established between the client and the server. A second secure connection is established between the device and the server through the client. The user then remotely logs into the server over the second secure connection using the device. The second secure connection is tunneled within the first secure connection, preventing the untrustworthy client from discovering personal information associated with the user. According to one feature, prior to forming the second secure connection, the user establishes a pairing relationship with the client by reading an address of the client using a reading mechanism. According to another feature, the device can receive marketing information in the course of a transaction.
