Adaptive image tracing technology based on fractional transform domain digital watermark
With the widespread use of internet applications,image dissemination has facilitated people's social lives and work,but it has also introduced security risks.Protecting the data ownership of image creators has become a pressing issue.This paper focuses on digital watermarking technology within image tracing,proposing an adaptive joint digital watermarking algorithm based on fractional-order transform domain.By utilizing fractional transform domain techniques instead of traditional transform domain methods,the digital watermark achieves greater robustness.Additionally,by adaptively selecting the transformation order,the al-gorithm balances the watermark's invisibility and robustness,ensuring the effectiveness of image tracing.
