Multi Socket Transmission System Application with Advanced Encryption Standard Algorithm to Support Confidential Medical Data Security

Medical data information plays an important role in supporting the confidentiality of diagnosis data, treatment, patient health history, examination results, and laboratory examination results to assist doctors in making accurate diagnoses and choosing appropriate treatment; now, this data has been integrated into the internet. The information system in this application is needed to be more efficient and effective in supporting medical data security. To integrate a confidential medical data privacy system, the information system is equipped with an encryption security system on the NIK, Diagnosis, Amnesia, and Therapy tables to guarantee the privacy of the data sent. The prototype multi-socket network-based communication system, PHP with the Laravel Framework, uses the Advanced Encryption Standard (AES) encryption algorithm using the same Key and Initialization Vector (IV) for encryption and decryption. It was designed to support the medical data security system using the Laravel NET website programming language framework and MySQL database. The system has been built based on two access rights, doctor, and super admin, where doctors can enter patient diagnoses. AES encryption will be applied to all data when downloaded by a doctor. The super admin can input access rights as a doctor but cannot see the patient because it has been encrypted with the AES algorithm through medical records diagnosis. Because when the data is sent, this system is tested using black box testing with 34 black box tests to ensure the confidentiality of confidential patient data. The system with the AES 256 algorithm can be useful for patient data security systems in hospitals.
