Privacy and biometrics for smart healthcare systems: attacks, and techniques

Biometric technology has various applications in smart healthcare systems, including patient authentication, health monitoring, telemedicine, clinical decision support, and personalized care. In addition, medical records contain sensitive and personal information, making them vulnerable to unauthorized access and theft. Because biometric data is distinct and unchangeable, unlike passwords or PINs, using biometric technologies in smart healthcare systems creates privacy problems. This creates privacy concerns as this information is highly sensitive and can be used to identify an individual, making it a valuable target for malicious actors. Subsequently, the storage and use of biometric data in smart healthcare systems must be handled with care to ensure that individuals’ privacy rights are protected. Privacy by design is a concept that emphasizes the importance of incorporating privacy considerations into the design and development of products, services, and systems. In this paper, we presented different forms of biometric factors and technologies and their applications in the smart healthcare system to enhance security and privacy in relation to principles of privacy by design. In addition, the study analyzed a variety of attacks and techniques that can be utilized to compromise biometric technology in a smart healthcare system and presented some open research questions.
