In our method, each block is classified as either a smooth block or a complex one based on its smoothness. In addition, these methods also suffer from their embedding technique, which limits the improvement of marked image quality.

The existing AMBTC authentication methods may not be able to detect certain malicious tampering due to the way that the authentication codes are generated. In this paper, we propose a high-quality image authentication method based on absolute moment block truncation coding (AMBTC) compressed images. The highest performance is seen in DWT-DCT-BFO watermarking. A variety of techniques are compared with the (NCC) Normalized Cross Correlations, (PSNR) Peak Noise Signal Ratio and IF (Image Fidelity). This technique uses a high-frequency image region. However, when compared to other optimizers, the BFO performs poorly in terms of convergence. It is a widely used optimization algorithm in a wide variety of applications. Bacterial foraging optimization (BFO) is an innovative technique for intelligent optimization. The proposed hybrid DWT-DCT Bacterial Foraging Optimization (BFO) technique improves the efficiency of watermarking digital images by 97%. Watermarking techniques have been progressing to shield media content such as text, audio, video, etc. The present study proposes a novel design and computation technique based on the discrete wavelet and discrete cosine transforms. New strategies and procedures for optimization are required.

There are various methods in literature, such as DWT and DCT, which take full energy, are seen and integrated. The method of transmitting information by imperceptibly embedding it into digital media is digital watermarking. This has a considerable impact on copyright holders' ability to safeguard their intellectual property rights. It is important to note that digital data can be copied without quality or content loss. However, the spread of digital media presents concerns for digital content owners. Digital multimedia data allows for robust and simple data editing and modification. AJRCOS, 9(3): 34-51, 2021 Article no.AJRCOS.69033 35 paper reviews IA techniques, watermark embedding techniques, tamper detection methods and discusses the performance of the techniques, the pros and cons of each technique, and the proposed methods for improving the performance of watermark techniques.ĭigital watermarking is getting more research and industry attention. Watermarking of a digital image is a mechanism by which the watermark is embedded in multimedia and the image of the watermark is retrieved or identified in a multimedia entity. Digital media, such as images, audio, and video, can hide content.

Digital image watermark is a strategy to ensure the reliability, resilience, intellectual property, and validity of multimedia documents. In the previous literature, several methods have been proposed to protect the authenticity of an image. An image authentication (IA) system is a solution to this difficult problem. As a result, images must be protected from attempts to alter their content that might affect important decision-making. The Internet has become one of the basic pillars of life and a solution to many of the problems left by the coronavirus. Generally, digital images are transmitted over insecure media, such as the Internet and computer networks of various kinds. Digital image authentication techniques have recently gained a lot of attention due to their importance to a large number of military and medical applications, banks, and institutions, which require a high level of security.
