In this paper a novel method for watermarking and ciphering color images is presented. The aim of the system is to allow the watermarking of encrypted data without requiring the knowledge of the original data. By using this method, it is also possible to cipher watermarked data without damaging the embedded signal. Furthermore, the extraction of the hidden information can be performed without deciphering the cover data and it is also possible to decipher watermarked data without removing the watermark. The transform domain adopted in this work is the Fibonacci-Haar wavelet transform. The experimental results show the effectiveness of the proposed scheme. © 2008 SPIE-IS&T.
