Abstract

A watermark signal, which is a unique sequence of random variables, by itself does not give a decisive indication of ownership. This work addresses the need to include meaningful information such that a string of English characters, numbers, and punctuation is embedded within the watermark signal, while the signal remains a sequence of random variables. We attempt to provide answers for (1) the maximum number of symbols the watermark signal can carry, and (2) the most practical and reliable way to implement this. We approached this problem as power constrained multiple signaling over an AWGN channel.
