Information technology advances have brought forth new challenges in healthcare information management, due to the vast amount of medical data that needs to be efficiently stored, retrieved, and distributed, and the increased security threats that explicitly have to be addressed. The paper discusses the perspectives of digital watermarking in a range of medical data management and distribution issues, and proposes a complementary and/or alternative tool that simultaneously addresses medical data protection, archiving, and retrieval, as well as source and data authentication. The scheme imperceptibly embeds in medical images multiple watermarks conveying patient's personal and examination data, keywords for information retrieval, the physician's digital signature for authentication, and a reference message for data integrity control. Experimental results indicate the efficiency and transparency of the scheme, which conforms to the strict requirements that apply to regions of diagnostic significance.
信息技术的进步给医疗信息管理带来了新的挑战，这是因为需要高效存储、检索和分发海量的医疗数据，并且必须明确应对日益增加的安全威胁。本文讨论了数字水印在一系列医疗数据管理和分发问题中的应用前景，并提出了一种补充性和/或替代性工具，该工具能同时解决医疗数据保护、存档和检索以及源和数据认证问题。该方案在医学图像中不可察觉地嵌入多个水印，这些水印包含患者的个人和检查数据、用于信息检索的关键词、用于认证的医生数字签名以及用于数据完整性控制的参考消息。实验结果表明了该方案的有效性和透明度，它符合适用于具有诊断意义区域的严格要求。
