First Claim
1. An apparatus comprising:
- a first module configured to send a text message over a wireless network in response to one or more user keystrokes, wherein said module generates a body of said text message and a security key to be transmitted along with said body of said text message; and
a second module configured to receive said body of said text message and said security key over said wireless network, wherein (A) said second module compares said security key to a set of known security keys to determine a match, (B) said match indicates whether said text message was generated from a known sender and (C) said first and second modules are part of a portable device.

Abstract
The present invention concerns an apparatus comprising a first module and a second module. The first module may be configured to send a text message over a wireless network in response to one or more user keystrokes. The first module may generate a body of the text message and a security key to be transmitted along with the body of the text message. The second module may be configured to receive the body of the text message and the security key over the wireless network. The second module compares the security key to a set of known security keys to determine a match. A match indicates whether the text message was generated from a known sender. The first and second modules may be implemented as part of a portable device.
