- We proposed an OFDM and watermarking based technology system for correspondent identity verification (CIVS) in military telecommunication digital channels. Correspondent personal identity signature (CPIS) is represented by digital watermark. The main idea of this system solution is to verify the end user who sends acoustic signal, e.g., speech, music, etc., via Internet, HF/UHF radio, modem, etc. OFDM modulation scheme is used to prepare secret digital signature. This signature is a single-use secret key used for correspondent verification, thus binary sequence of that key is changing for every session. We describe transmitter and receiver block scheme. The results of experiments for both ideal and degraded signals are described in details too. The results are summarized with comments and conclusion.
