- •
PCA coefficients are used to generate information watermarks, and the authentication watermarks are generated using SVD coefficients.
- •
The embedding position is generated by a chaotic map, and it improves the security of the proposed method.
- •
Watermarks are embedded into the mid-frequency bands by using our proposed SDPQ method.
