Design of a secure medical data sharing system via an authorized mechanism

In recent years, the electronic medical records can be easily stored with the rapid development of healthcare technology and cloud computing. However, the patient's medical information security is currently concern issue. Despite of many literatures discussed about it, these literatures still face many security challenges. Therefore, we propose an authentication scheme based on cloud environment. In our scheme, we allow people to use the digital develop mechanism to achieve the sharing medical data. By the way, the biometric fingerprint feature and digital signature are used to ensure the security of medical information in our scheme.
