Watermarking: Some Best Practices
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 4
Abstract
To protects intellectual property rights, the amount of exchanged digital content calls are rapidly growing based on efficient and practical techniques. During the past two decades, watermarking techniques have been presented to embed and detect information within such contents, with different four key requirements at hand, that are – capacity, invisibility, robustness, and security. So far, researchers mainly focused on the first three. Earlier work used novel DFT watermarking scheme featuring perceptually optimal visibility versus robustness. The system should possess good quality of images. With time goes new techniques are evolved with different quality features. Each system’s technique varies from one another. The techniques used, merits and demerits of different watermarking systems are studied and analyzed in this paper. We can get a detailed comparative study of different systems of watermarking.
