“…A copyright vendor (owner) may embed watermarking comprising the copyright data in the host video if decoded; it may be utilized as evidence of the rights. Hence, as the purpose of videos was to delay the rights of the video content by eliminating the watermark, it must be robust to different threats in real-time applications [30,31].…”

With the rapid advancement of technology, ensuring authentication and security in communication over long distances has become a primary concern. The film industry is particularly vulnerable to the unauthorized distribution of digital videos, which can be easily disseminated to a global audience due to widespread internet access. Video watermarking has gained significant importance in various applications such as copyright protection, security, fingerprinting, copy control, and annotation. Watermarking, whether in the form of an image, audio, or video, is a technique used to embed additional information within a digital video signal. This embedded information is utilized for copyright owner detection. Consequently, several methods for digital video watermarking (DVW) have been developed to address this issue. Watermarking has emerged as a crucial means of verifying ownership, ensuring authenticity, and safeguarding copyrights. Researchers employ watermarking techniques to hide confidential information, which can be made either visible or obscured based on the user's requirements. This approach plays a vital role in determining the ownership of information. To ensure secure watermarking, an optimization process is often employed. This paper presents an overview of the diverse trends and techniques adopted in the field of digital watermarking. It aims to provide a comprehensive guide to research scholars interested in exploring this area of study.

“…Propose variable number of bits are embedded into different blocks categorized into four levels (lower, lowermiddle, higher-middle and higher) based on average of pixel value differences in nine-pixel blocks. Ghosh et al (2015) developed an Extended Hamming Code (EHC) using dual purpose spatial domain algorithm coupling steganography and cryptography. They achieved good imperceptibility and robustness.…”

Due to the vast interchange of images over the internet, exchanging secret message hidden in these images would be encouraged and the technique is referred to as image steganography. Hiding the secret data into the least significant bits of the images pixels is a common practice. However, the choice of the hidden key and the efficiency of utilizing all pixels of the carrier image is of great importance. This paper presents a new technique for key generation and embedding/extraction processes for image steganography. The randomness of secret key required for the embedding process is achieved by using the seven segment display patterns with different dimensions. Full embedding efficiency is also achieved through. Experimental measurements and comparison with traditional steganography using LSB have confirmed the feasibility of the proposed scheme. As it produces highly imperceptible stego-images, besides the key randomness for selecting the pixels, which leads to the addition of huge difficulties against attackers and provides genuine protection for the hidden information.

Copyright protection and ownership proof of digital multimedia are achieved nowadays by digital watermarking techniques. A text watermarking algorithm for protecting the property rights and ownership judgment of color images is proposed in this paper. Embedding is achieved by inserting texts elements randomly into the color image as noise. The YIQ image processing model is found to be faster than other image processing methods, and hence, it is adopted for the embedding process. An optional choice of encrypting the text watermark before embedding is also suggested (in case required by some applications), where, the text can is encrypted using any enciphering technique adding more difficulty to hackers. Experiments resulted in embedding speed improvement of more than double the speed of other considered systems (such as least significant bit method, and separate color code methods), and a fairly acceptable level of peak signal to noise ratio (PSNR) with low mean square error values for watermarking purposes.
