“…This can be achieved by adding a watermark to the previously watermarked signal but in a different frequency band. This can be achieved by using the same mother wavelet but with Thus, multi-level watermarking can be defined as a process of embedding multiple watermarks to the same host signal, where each watermark can be detected or extracted separately and securely with corresponding keys without the knowledge of other watermarks in the host signal (Sheppard et al, 2001). Multi-level watermarking can be used to increase payload capacity and achieve different levels of robustness which offer different levels of security.…”

In this paper, a robust and perceptually transparent single-level and multi-level blind audio watermarking scheme using wavelets is proposed. A randomly generated binary sequence is used as a watermark, and wavelet function coding is used to embed the watermark sequence in audio signals. Multi-level watermarking is used to enhance payload capacity and can be used for a different level of security. The robustness of the scheme is evaluated by applying different attacks such as filtering, sampling rate alteration, compression, noise addition, amplitude scaling, and cropping. The simulation results obtained show that the proposed watermarking scheme is resilient to various attacks except cropping. Perceptual transparency of watermark is measured by using Perceptual Evaluation of Audio Quality (PEAQ) basic model of ITU-R (PEAQ ITU-R BS.1387) on Speech Quality Assessing Material (SQAM) given by European Broadcasting Union (EBU). Average Objective Difference Grade (ODG) measured for this method is −0.067 and −0.080 for single-level and multi-level watermarked audio signals, respectively. In the proposed single-level digital audio watermarking scheme, the payload capacity is increased by 19.05% as compared to the single-level Chirp-Based Digital Audio Watermarking (CB-DAWM) scheme.

“…Recently, the usage of multiple watermarks has attracted several proposals [13,14]. While in most of the cases, multiple watermarking is used in multimedia applications, it has also been used in other applications like protection in wireless sensor networks [15]. A review of the various methods used for multiple watermarking is given by [16].…”

Advancement in communication medium is producing large volume of digital information which needs to be protected. Watermarking is a technique that is used to hide secret signal into digital signal in a manner that does not reduce overall quality of the original signal. In relation to digital image watermarking, another area that is drawing attention is the multiple watermarking, where more than one watermark is embedded into single multimedia object. M ultiple watermarks are normally proposed as a method to provide extra security to an image by embedding two or more secret messages into the cover image. In the present research work, the concept of multiple watermarking is used to hide both copyright and authentication information into a color image. For this purpose a wavelet transformation based on texture properties and secret sharing us ing visual cryptography is used. Experimental results indicate that the proposed watermarking scheme is highly robust and does not degrade the original signal.

“…Apart from Sheppard et al, 5 composite and successive watermarking are hardly discussed in literature. Only Shieh et al 6 propose a successive watermarking scheme where the first mark is embedded in a vector quantization domain whereas the second watermarking schemes operates in the middle DCT frequency band.…”

Watermark interference is a threat to reliable detection in multiple re-watermarking scenarios. The impact of using disjoint frequency bands and/or different embedding domains in limiting those interferences is evaluated and compared. Employing disjoint frequency bands for embedding different watermarks turns out to be more effective and is capable of maintaining reasonable detection correlation in multiple embedding applications.
