A secure biometrics-based authentication scheme for telecare medicine information systems

Area of Science:

• Health Informatics
• Cybersecurity
• Biometrics

Background:

• Telecare Medicine Information Systems (TMIS) offer convenient remote access to medical services and information.
• Patient privacy in TMIS is crucial, necessitating robust authentication schemes.
• Biometrics-based authentication is increasingly employed for enhanced security in healthcare systems.

Purpose of the Study:

• To analyze the security of Tan's recently proposed biometrics-based authentication scheme for TMIS.
• To identify vulnerabilities within Tan's scheme, specifically against Denial-of-Service attacks.
• To propose an improved authentication scheme that enhances security and performance for TMIS.

Main Methods:

• Vulnerability analysis of Tan's biometrics-based authentication scheme.
• Development of a novel, enhanced authentication scheme building upon Tan's work.
• Comparative security and performance evaluation of the proposed scheme against the original.

Main Results:

• Tan's biometrics-based authentication scheme was found to be vulnerable to Denial-of-Service attacks.
• The proposed improved scheme effectively mitigates the identified Denial-of-Service vulnerability.
• Security and performance analyses confirm the enhanced capabilities of the improved scheme.

Conclusions:

• Tan's authentication scheme for TMIS requires security enhancements due to identified vulnerabilities.
• The proposed improved scheme offers a more secure and efficient solution for TMIS authentication.
• This research contributes to safeguarding patient privacy and ensuring reliable access in telecare medicine.
