The healthcare IOT (Internet of Things) measures the patient’s medical details continuously and stores it in the database, so that the medical details can be accessed by the users at any time. As the medical details of the patient is sensitive, it must be secured. So, the secured healthcare monitoring system is needed to encrypt the medical files and it can be securely accessed by the authorized users. The medical details of the patients are collected from healthcare IOT and these details can be combined into medical files. These files are stored in the database and then shared to the authorized users securely. To prevent patient’s privacy, the medical files of the patients are encrypted before storing the files in the database. The authorized users only can access the medical details of the patient. The Lightweight Break-Glass Access Control (LiBAC) system supports two different ways for retrieving encrypted medical files which includes attribute-based access and break-glass access. In normal circumstances, the attribute-based access mechanism allows the data user to decrypt the medical details of the patient only if his attribute set satisfies with the access policy of the medical file. In emergency circumstances, the break-glass access mechanism ignores the normal access policy of the medical file but allows timely access to the medical file by Emergency Contact Person (ECP) in order to save patient’s life. The LiBAC system is lightweight, since the processing speed of storing and retrieving the medical files is very fast.
