INFORMATION PROTECTION DEVICE

摘要

A method for communication includes coupling an information protection device (34) to communicate via a local interface (36) with a local computer (28) operated by a user (22), the information protection device having an input transducer (58) associated therewith. A communication session is initiated between the local computer and a remote computer (24) over a network (26). The information protection device receives an access code input by the user via the input transducer and encrypts the access code using an encryption key held by the information protection device. The encrypted access code is conveyed from the information protection device over the local interface to the local computer and from the local computer to the remote computer over the network in order to authenticate the user at the remote.
