A Fingerprint Authentication for Android-Based Healthcare Appointment Scheduling System

Introduction: Healthcare organizations maintain patient sensitive data that requires to comply with privacy and security laws. At the same time should provide a system with ease of access. Objective: The main purpose of this research is to develop a mobile application that can manage, and control patients flow at the healthcare by allowing the doctor to upload their appointments and then allow clients (patients) to book one of the available slots in an efficient and effective way. Methods: A survey has been conducted on 100 android app users in Malaysia, it has been observed that businesses’ owners does not trust current mobile appointment applications and prefer to use the traditional methods, which is on first come, first serve bases. Aside from that, current issues that are faced by the users are that most of the mobile appointment applications are unsecured and there is no security control over the account holders for these applications. Results: The developed application also includes extra feature such as secure chatting function that links between the users of the app and let them discuss any type of inquiries related to the booked appointment. AES, SHA-256 and SCRYPTE algorithm has been implemented successfully on the developed application and hence will increase the layer of security and keep user data in a safe manner. AES encryption used to encrypt the users chatting messages while the SHA-256 used to hash the secret key that used to encrypt and decrypt data. Moreover, Conclusion: Biometric fingerprint authentication has integrated with the system in order to solve the existing security flaws of the current appointment applications as well as email verification for avoiding the anonymous user and increase the overall security features.
