Robust Multimedia Watermarking

Abstract

The data transmission on network channel has increased tremendously in the past few decades. Watermarking is a process to add watermark as a digital signal, label, or tag into a cover media. The primary requirements of multimedia watermarking are robustness and embedding capability. The robustness is defined as the strength of an algorithm to repel the noise. However, it is challenging to achieve both at the same time. The numerous characteristics of watermarking are very imperative in the multimedia watermarking system. The researchers are using watermarking schemes in various applications such as military, digital forensics, medical, and so on. Attacks of these watermarking harm or uncover the secret information carried in the watermark. Potential researchers have been presented various techniques for balancing or improving these concerns. This chapter reviews the recent multimedia watermarking techniques on the basis of robustness and embedding capability. The characteristics, applications, and attacks on multimedia watermarking techniques are introduced.
