Patent Images
1. A method for digitally signing data comprising the steps of:
- providing a cellular phone having capabilities to store a private key, to accept locally entered data from a user, to digitally sign the locally entered data using the private key such that one or more digital strings are produced;
directly entering the data, by the user, in the cellular phone;
computing, by the cellular phone, a digital signature of the data using the private key;
encoding, by the cellular phone, the digitally signed data to sound; and
generating, by the cellular phone, the digitally signed data as acoustic sound waves.

Abstract
Methods for identifying a remote user of a portable device by using the portable device to encode sound corresponding to the identification of the remote user. The sound is received by a microphone external to the portable device and converted to an electrical signal. The electrical signal is transmitted to a processing device, that may be remote to the microphone, where the electrical signal is processed and the identification of the remote user is completed.
