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
protection (security of ownership rights fo Platform: |

issue of copyright protection of multimedia data dist ributed via t he communication channel . The result s
show t hat t he embedded watermark is robust to normal data manip ulations , such as adding noise ,
cropping , rotation , and J PEG compression. Because t he design concept and met hodology based on
geomet ric parameter s of Virt ual2Optics was adopted , t he proposed 32D watermarking system has good
security. There are large degrees of f reedom existing for designing a security lock ( s)/key ( s) , including
multiple lock ( s)/key ( s) and multi2dimensional lock ( s)/key ( s) . Numerical experiment s are performed to
