A blind color digital image watermarking method based on image correction and eigenvalue decomposition

作者：

Highlights：

• The geometric attributes of the attacked image are used to correct the image.

• The private keys are encrypted by the integer pairing function with high security.

• The encrypted watermark is encoded by the Hamming code with strong robustness.

• The eigenvalues are calculated by EVD and are quantified to embed the watermark.
