In health care, medication errors can result in serious health risks to patients, and hospitals require a secure medication administration system to prevent such errors. This paper therefore proposes a secure medication administration method based on threshold sharing technology. When a patient visits a doctor and the doctor prescribes n medications, a photo and the personal information of the patient are encoded into n QR code transparencies that can be decoded by common QR code scanners available for smartphones. The prescription and n QR code transparencies are then stored in a hospital’s medication administration system. When the patient receives their medicine, they can scan these n QR code transparencies using a smartphone to ensure that they have all the medicines prescribed by the doctor; this function is accessible even if the patient’s phone does not have Internet access. The main purpose of the proposed system is to prevent hospitals from giving medicine to the wrong patient, or giving less than the prescribed dosage of medicine to the patient. The focus is not on the internal medicine packaging process in hospitals but on reducing the probability of counter staff giving medicine to the wrong patient. This function is of considerable importance to non-English-speaking people who are not used to reading medicine names in English.

基于可视密码术的新型QR码药物管理系统

在医疗保健中，用药错误可能会给患者带来严重的健康风险，并且医院需要安全的用药管理系统来防止此类错误。因此，本文提出了一种基于阈值共享技术的安全药物管理方法。当患者去看医生并且医生开出n种药物时，患者的照片和个人信息将被编码为n个QR码透明胶片，可通过智能手机可用的普通QR码扫描仪进行解码。然后将处方和n个QR码透明胶片存储在医院的药物管理系统中。当患者接受他们的药，他们可以扫描这些ñ使用智能手机的二维码透明胶片，以确保它们具有医生处方的所有药品；即使患者的电话无法访问互联网，此功能也可以使用。提议的系统的主要目的是防止医院向错误的患者提供药物，或者向患者提供少于处方剂量的药物。重点不在于医院的内部药品包装过程，而在于减少柜台人员向错误患者提供药品的可能性。对于不习惯以英语阅读药物名称的非英语国家的人来说，此功能非常重要。
