Audio watermarking techniques generally include embedding a noiselike sequence (the watermark) into a signal. This sequence must remain secret, since its knowledge allows the erasure of the watermark. The detection is performed through a correlation measure between the watermark and the possibly jammed watermarked signal. Only the signal owner is able to carry out the detection, which is private. This paper presents a novel approach that uses a cyclostationary sequence as the watermark. While still privately detectable through a correlation measure, the watermark may also be publicly detected by exploiting its property of cyclostationarity. The suitable choice of cyclostationary sequences enables one to hide both private and public data in the signal.:
