“…As per the research of Singh et al [36], the DCT-based technique is effective in comparison with spatial domain methods. The reason behind this is because the watermark embedded into the image under such a technique is not possibly destroyed by any attach as the middle-frequency coefficients are used for embedding, and thus the image's visibility is not impacted.…”

“…Therefore, it can be interpreted based on these results that the use of DWT, DCT, and OTP for watermarking the images is highly effective as any changes to the image do not harm the watermark. The DCT-based strategy is more effective than spatial domain methods [36]. The reason for this is that the watermark implanted in the image using this technique cannot be erased by any attach since middle-frequency coefficients are utilized for embedding; hence the image's visibility is unaffected.…”

In this modern era, it has become much simpler to replicate, sell, and copy the copyright owners' works without their permission as a result of the expansion of digitalization, and it is difficult to identify such violations, posing a threat to the creators' and copyright owners' rights. For many years, the internet has been regarded as one of the most serious threats to copyright, and the content available has varying levels of copyright protection. On the internet, there are numerous copyrighted works, including e-books, movies, news, and so on. Therefore, by using watermarking and steganography techniques, these issues can be solved, which are based on the author's signature information or logo. This paper concluded that the techniques of discrete cosine transform (DCT), discrete wavelet transform (DWT), one-time pad (OTP), and playfair are highly effective when used together to watermark an image or embed a secret message, our lab results validate that our algorithm scheme is robust against several sets of attacks, where the algorithm was assessed by computation of many evaluation metrics such as mean square error (MSE), signal-to-noise ratio (SNR), and peak signal-to-noise ratio (PSNR).

“…Una vez obtenidos los coeficientes de aproximación del audio marcado, se seleccionan P valores de acuerdo a la información contenida en la semilla. Para cada uno de estos P coeficientes de aproximación, se aplica la extracción de bits del método QIM, correspondiente a la ecuación (2). Por cada coeficiente, se obtiene un bit, es decir, un pixel binario de la marca.…”

“…Dentro de los sectores más afectados por la copia ilegal de contenido se encuentra la industria musical, por ello se hace necesario brindar protección a los derechos de autor y el uso autorizado de la información, buscando mecanismos en donde se pueda identificar el propietario del contenido. Uno de los mecanismos más utilizados en la protección de contenido musical es el marcado de agua, ya que permite "firmar" el audio sin que se deteriore su calidad [1,2].…”

“…Nowadays, 3D mesh has found many applications in the field of virtual reality, computer‐aided design (CAD), entertainment and so on [5 ]. Although abundant watermarking schemes have been designed for digital images, audios and videos due to much exposure of such content over the internet [6–9 ], much less work is done in the domain of 3D mesh watermarking as schemes fabricated for 2D domain cannot be readily applied to 3D models.…”
