Currently, the use of biometric systems is increasing following the increase in the non-face-to-face security transactions in the Health Care sector, where smart devices are extensively used. Additionally, hospital patients or their guardians had to sign every medical/surgery consent form with a pen. Currently, hospitals are attempting to digitalize the form to avoid its loss or delay to the operating room. Thus, this study proposes a surgery consent signature authentication system for the mobile health care system. Along with the vein or the fingerprint recognition technology, the smart electronic signature recognition technology is regarded as a new type of security solution for Mobile Health Care, which is a compound of Health Care and technology, or a smart contents and display technology. Thus, this study proposes a surgery agreement signature authentication system for Mobile Health Care while using the techniques, such as database segment units comparison in the cloud, Bag of Word, etc. The proposed system was implemented with Java language and developed in a way the reference signature stored in advance in a cloud database to be compared with the signature currently entered. For the comparison, the segment matching, spatial pyramid matching, and boundary matching techniques were used in addition to the Dynamic Time Warping (DTW) algorithm. Additionally, the system has been made lighter than the existing experimental products, so that it is easier to embed the system into a smart phone, tablet, or others. The Test Bed experiment result showed that the system operated flexibly.

移动医疗手术协议签名认证系统

当前，随着在医疗保健领域中广泛使用智能设备的非面对面安全交易的增加，生物识别系统的使用也在增加。此外，医院患者或其监护人必须用笔在每份医学/手术同意书上签名。当前，医院正在尝试将表格数字化，以避免表格丢失或延迟到手术室。因此，本研究提出了一种用于移动医疗系统的手术同意书签名认证系统。与静脉或指纹识别技术一起，智能电子签名识别技术被视为移动医疗保健的一种新型安全解决方案，它是医疗保健和技术或智能内容和显示技术的组合。从而，这项研究提出了一种用于移动医疗的手术协议签名认证系统，同时使用了诸如云中的数据库段单位比较，Word的Bag等技术。该提议的系统使用Java语言实现并以参考签名的方式开发预先存储在云数据库中，以便与当前输入的签名进行比较。为了进行比较，除了动态时间规整（DTW）算法之外，还使用了段匹配，空间金字塔匹配和边界匹配技术。此外，该系统比现有的实验产品更轻巧，因此更容易将系统嵌入到智能手机，平板电脑或其他产品中。测试床实验结果表明该系统运行灵活。
