摘要

This paper provides a comparative research on hybrid watermarking methods in medical image security. Securing medical information like patient records and medical images, when stored and transferred is a significant challenge. Conventional watermarking techniques might not offer adequate protection, resilience and authentication. Hence, hybrid methods involving the integration of watermarking and encryption, as well as, spatial/frequency domain methods are more useful in improving security. The paper contrasts different hybrid methods in terms of image quality and strength in terms of Peak Signal-to-Noise Ratio (PSNR). PSNR values in the surveyed methods are reported to be between 39 dB and 59 dB, which suggests better imperceptibility and quality of reconstruction. Medical data like CT scans, MRI, X-ray and ultrasound needs confidentiality, integrity checks and secure access. The results indicate that hybrid watermarking systems offer high confidentiality, robustness, authentication and protection compared to traditional watermarking systems.
