In this paper, we present a robust image watermarking approach to hide DNA sequence data into fingerprint templates for copyright protection based on the discrete wavelet transform. A multi-bit watermark, based on DNA data, is embedded into the low frequency sub-band of the fingerprint image. During the inverse process, we employ DNA decoding to extract the image signature from the watermarked image. We evaluate our proposed method using statistical measures including mean squared error, peak signal-to-noise-ratio, and structural similarity index, and the experimental results confirm that the watermarks generated using our approach are invisible.
