Hiding Information under Speech
Abstract
Jerry Weisman of Santa Clara, CA, who has been coaching CEOs for many years on how to sell themselves, wrote about making successful presentations. Weisman said, "simple but accurate charts are essential to making a presentation more effective." Unfortunately, until now the secure phone has been no more functional than a telephone -- a device capable of transporting only sounds like the human voice and surrounding sounds. The authors believe that a future secure phone should move beyond 20th century abilities and be capable of transmitting essential visual aids (e.g., key words, key phrases, and simple graphics or hand-scribbled notes) to complement voice communication. They are currently implementing such a phone. It operates in a real-time demonstrable prototype in which a Variable Data Rate (VDR) voice encoder is the core voice encoder. The latter is now being developed by SPAWAR PMW-160 as a future Navy secure phone for future Naval Voice over Internet Protocol (VoIP) applications. With the technology described in this report, two tactical commanders can coordinate a tactical assault plan not only verbally, but also visually by exchanging drawings of troop movements or other visual information to enhance the effectiveness of voice coordination. This is intended to be a secure voice system for the 21st century.
