System to identify whether a text message is from a trusted source

摘要

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.
