This paper presents a new approach for speech signal watermarking using encrypted watermarks. The objective of this approach is to increase the degree of security of speech watermarking. In the proposed framework, watermark embedding is implemented with singular value decomposition due to its robustness to attacks. Moreover, two encryption schemes are tested for watermark image encryption; chaotic encryption due to its permutation nature and data encryption standard (DES) due to its diffusion nature. Overall and block-by-block watermarking scenarios are tested and compared for speech signal watermarking. Different modes of operation of the DES are investigated for watermark image encryption. These modes are the electronic code book, cipher block chaining, cipher feedback, and output feedback (OFB) modes. Simulation results reveal that the DES with OFB mode and the chaotic Baker map encryption make the system less sensitive to attacks with good quality of extracted watermarks.
