Improvement of a Privacy Authentication Scheme Based on Cloud for Medical Environment

Area of Science:

• Health Informatics
• Cybersecurity in Healthcare
• Telemedicine

Background:

• Telecare Medicine Information Systems (TMIS) facilitate remote medical care but often lack data encryption, risking patient privacy.
• Existing cloud-based medical models (2014) improve remote access but fail to ensure patient anonymity and message authentication.
• Current systems store medical data but do not enable direct patient-doctor consultations, limiting telehealth utility.

Purpose of the Study:

• To propose a novel authentication scheme for Telecare Medicine Information Systems (TMIS).
• To enhance patient privacy through anonymity and unlinkability in remote healthcare interactions.
• To enable direct, remote consultations between patients and doctors while ensuring message authentication.

Main Methods:

• Development of a new authentication scheme integrating anonymity, unlinkability, and message authentication.
• Implementation of the proposed scheme within an Android system for practical demonstration.
• Evaluation of the scheme's efficiency based on computation cost.

Main Results:

• The proposed scheme successfully provides patient anonymity and unlinkability.
• Message authentication is achieved, securing communications within the TMIS.
• The system allows for direct and remote consultations between patients and doctors.
• The implemented Android system demonstrated the workability of the proposed scheme.

Conclusions:

• The novel authentication scheme significantly enhances security and privacy in TMIS.
• The system offers improved efficiency and direct patient-doctor interaction capabilities.
• This approach addresses limitations of previous models, providing a more comprehensive telehealth solution.
