Description: On Designatedly Veried (Non-interactive)Watermarking Schemes-Although many watermarking schemes consider the case of
universal veri¯ ability, it is undesirable in some applications. Designated
veri¯ cation is a possible solution for this problem. Watermarking scheme
with (non-interactive) designated veri¯ cation through non-invertible
schemes was proposed by Lee et al [11] in 2003, to resolve multiple wa-
termarking problem. Yoo et al [14] proposed a very similar watermarking
scheme. In this paper, we propose a cryptanalytic attack on both of these
schemes that allows a dishonest watermarker to send illegal watermarked
images and to convince the designated veri¯ er or customer that received
watermarked images are valid.We modify the above schemes to overcome
the attack. Further, we also propose a new robust watermarking scheme
with (non-interactive) designated veri¯ cation through non-invertible wa-
termarks. Interestingly, our scheme can be extended for joint copyright

Description: Abstract- H.264/AVC is becoming a popular video codec for
its better compression ratio, lower distortion and applicability
to portable electronic devices. Thus, issues of copyright
protection appropriate for this standard become very
important. In this paper, a new blind SVD (Singular Value
Decomposition) - DCT combined video watermarking scheme
for the ".264 standard is proposed. The proposed method is a
blind watermarking algorithm as the hidden information can be
extracted without the original video and the original singular
values. To reduce visual quality degradation caused by
coefficients modifying, the perceptual model and block selection
mechanism are introduced to control the modification strength.
The performance of the proposed algorithm is evaluated with
respect to imperceptibility, robustness and data payload.
Experimental results reveal that the proposed scheme achieves
enough robustness while preserving the perceptual quality.-Abstract- H.264/AVC is becoming a popular video codec for
