  7. Abstract:
  8. In electronic health, data is stored and retrieved electronically at the local or national level for clinical, educational and administrative purposes. The importance of data from citizens, patients, professionals and providers of healthcare and policy-makers points of view make it a valuable asset. In recent years, we confront the emergence of the Internet of Things and its widespread use in electronic health. In this area, health sensors such as a heart rate sensor, a blood glucose sensor, or a respiratory sensor provide information about each person that can be sent through the network to the physician. Such a continuous remote monitoring allows physicians to take better care of patients and, if necessary, provide medical services at the right moment. It also eases monitoring patient health status for nurses in different parts of the hospital. Nevertheless, the use of the Internet of objects and access to the electronic records of patients in these environments (remotely or locally) confronts a lot of challenges. For example, access to the records of patients based on physical location of the doctor, recognition of emergency and granting temporary access to the attending physician, and especially granting legal access to all or part of the permissions (by patient or physician) to another doctor are some of the issues in this area. In recent years, various models have been developed to solve these issues based on the needs of the healthcare environment, but these models have not meet all the requirements. In this study, an access control system with access delegation in E-health has been designed and implemented to preserve security of the clients in case doctors and nurses get access to information based on their location from sensors when they may impose security challenges in these environments. The proposed solution includes appropriate data structures, protocols and mechanisms to grant the right accesses to mentioned parties. Finally, in this thesis, the implementation of the model is done as an application in the Android operating system. The validity of the proposed model is evaluated for the information of a hospital and based on the defined scenarios related to them
