A data-hiding technique called the "bipolar multiple-number base" was developed to provide capabilities of authentication, integration, and confidentiality for an electronic patient record (EPR) transmitted among hospitals through the Internet. The proposed technique is capable of hiding those EPR related data such as diagnostic reports, electrocardiogram, and digital signatures from doctors or a hospital into a mark image. The mark image could be the mark of a hospital used to identify the origin of an EPR. Those digital signatures from doctors and a hospital could be applied for the EPR authentication. Thus, different types of medical data can be integrated into the same mark image. The confidentiality is ultimately achieved by decrypting the EPR related data and digital signatures with an exact copy of the original mark image. The experimental results validate the integrity and the invisibility of the hidden EPR related data. This newly developed technique allows all of the hidden data to be separated and restored perfectly by authorized users.
一种名为“双极多数字基”的数据隐藏技术被开发出来，用于为通过互联网在医院之间传输的电子病历（EPR）提供认证、整合和保密功能。所提出的技术能够将那些与电子病历相关的数据，如诊断报告、心电图和医生或医院的数字签名，隐藏到一个标记图像中。该标记图像可以是医院用于识别电子病历来源的标记。医生和医院的那些数字签名可用于电子病历认证。因此，不同类型的医疗数据可以整合到同一个标记图像中。通过使用原始标记图像的精确副本对与电子病历相关的数据和数字签名进行解密，最终实现保密性。实验结果验证了隐藏的与电子病历相关数据的完整性和不可见性。这种新开发的技术允许授权用户完美地分离和恢复所有隐藏数据。
