A blind robust watermarking scheme based on svd and circulant matrices
Multimedia security has been the aim point of considerable research activity
because of its wide application area. The major technology to achieve copyright
protection, content authentication, access control and multimedia security is
watermarking which is the process of embedding data into a multimedia element
such as image or audio, this embedded data can later be extracted from, or
detected in the embedded element for different purposes. In this work, a blind
watermarking algorithm based on SVD and circulant matrices has been presented.
Every circulant matrix is associated with a matrix for which the SVD
decomposition coincides with the spectral decomposition. This leads to improve
the Chandra algorithm [1], our presentation will include a discussion on the
data hiding capacity, watermark transparency and robustness against a wide
range of common image processing attacks.Comment: 12 pages, 6 figures, 5 tables, Second International Conference on
