“…It may be authenticated using active or passive monitoring. The existing and actual videos are compared previously, and a maximum number of data storage is needed, if the security technique of watermarking may impart the vigorous surveillance in an imperceptible and sturdy way [28].…”

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.

“…However, with the help of steganography, it would be very difficult to do so. In [15] Ouslim et al described in detail how biometric data can be transferred onto a computer network without an attack or even without being detected. They also highlight the possible location of such an attack, a sensor location, where most of the fingerprint is left.…”

This paper evaluates and analyses the discrete wavelet transform (DWT) frequency bands for embedding and extracting of the biometric data using DWT single level and multilevel watermarking approach with and without the use of alpha blending approach. In addition, singular value decomposition (SVD) combined with DWT is used to embed and extract the watermark image. The performance of compression and decompression approaches has been analyzed to examine the robustness and to check whether the compression function does destroy the integrity of the watermarked image. We investigate the proposed approach to understand how robust the watermarked on different sub-band is against the image processing and geometric attacks. The experimental results show that the DWT multilevel and SVD watermarking approach is more robust than the other watermarking methods implemented in this paper. The DWT bands dominate the approximate coefficient band (LL) in high-intensity alpha value. When the intensity is reduced, the coefficient standout to be very robust against the remaining bands.

Özetçe-Bu çalışmada Eliptik Eğri Kriptografisi (ECC) üzerinde Koblitz Metodu kullanılarak video dosyaları içine EnÖnemsiz Bit (LSB) tabanlı bilgi gizlenmesi amaçlanmıştır. Alıcıya iletilmek istenen mesaj ASCII karakterlerine dönüştürüldükten sonra, tek indise sahip karakterler Koblitz Metoduyla şifrelenerek (x,y) ikilileri elde edilir ve bu ikililerin koordinat noktalarını ifade ettiği varsayılır. Tek indise sahip bu noktaların ilgili frame üzerindeki piksel değeri, kendinden sonra gelen çift indisli ASCII karakterin ikilik tabandaki değeri ile LSB metoduyla değiştirilir. Mesajın tüm karakterleri için aynı işlem tekrarlandıktan sonra mesaj video frameleri içine gizlenmiş olur.

After which the message to be sent to the recipient converted into ASCII characters, single index characters are encrypted by Koblitz's Method, (x,y) pairs obtained, and it is assumed that these pairs (x,y) express as a coordinate points. The pixel value on the relevant frame of single index points replaced with next double index ASCII character's binary value using LSB method. After repeating the same process for all characters in the message, the message is hidden into the video frames.
