I suspect that but few of the very many animals which live on the beach between high and low watermark are preserved.
The former is caused by the fact that the seller knows the information to partially remove the noise sequence embedded into the digital content sent to buyers and so it can have access to the decryption keys that carry the client-specific watermarks. Consequently, the seller can fabricate piracy to frame an innocent buyer, since it can make and distribute copy of digital content purchased by a buyer, then accuse the buyer of illegal distribution.
The problem is there is a gap between image capturing the embedding of the watermark were in most cases watermarks are embedded offline after the image captured using external software [5].
Results of this theoretical and mathematical study ended up to use the second level of SVD to increase stability of the region of interest to embed watermarks. More stability leads to more robustness.
where W and W' represent the original and extracted watermarks of dimension M x N each, respectively.
In this paper, a watermarking algorithm is proposed and analyzed using RDWT-SVD and Compressive Sensing for multiple watermarks protection.
To examine the robustness of presented technique many attacks such as average filtering (AVGFL), Joint Photographic Expert Group (PEG) compression (JPEGC) rotation (ROT), simple blurring (SPBL), Y-Shearing (YSHR), motion blurring (MOBL), scaling (SCAL), salt & pepper noise (S&PNO), Cropping (CROP), affine transformation (AFTRA), Gaussian noise (GANO), X-shearing (XSHR), histogram equalization (HEQ) and, translation (TRL), were used to destroy the watermarks. The NC values for different scaling factors against all above-mentioned attacks are shown in Table III.
To sidestep the problem of effective watermark removal, Google employs a technique called 'Warping.' As the vulnerability being exploited by Google is based on the consistency of watermarks, to counter the problem, inconsistencies are introduced while layering the watermarks onto an image.
Britannia watermark shows a large oval enclosing a seating crowned lady (Britannia) who holds a flower in one hand and supports a spear by the other hand By Sheikha Al-Loughani KUWAIT, April 18 (KUNA) -- Since early days of the state, Kuwaiti leaders and officials tapped all means to protect official documents and manuscripts from counterfeit, watermarked papers was most common among them.
Then, for the high-frequency part, Compressive Sensing (CS) is used to conduct encryption so as to vacate space for watermark embedding.
