Digital trust in healthcare is considered a fundamental pillar for ensuring the effectiveness of intelligent medical systems and protecting patients’ sensitive data. With the expanding use of modern technologies, such as artificial intelligence, the Internet of Medical Things, and electronic health records, guaranteeing the security of digital information and ensuring the credibility of these systems has become critically important to maintaining the quality and continuity of healthcare. Digital trust is not merely about data protection; it is a central factor in enhancing patient engagement with healthcare systems and improving the efficiency of medical decision-making. Intelligent systems contribute to providing more accurate and faster medical services; however, they are simultaneously exposed to multiple risks, including cyberattacks, unauthorized intrusions, and manipulation of medical information, which may result in serious consequences for patient health. Therefore, building digital trust requires the integration of advanced security strategies, including data encryption, monitoring system access, and implementing multi-factor authentication mechanisms to ensure that only authorized users can access sensitive information. Furthermore, regulatory policies and digital governance play a crucial role in strengthening trust by establishing clear standards for protecting personal data and ensuring that healthcare institutions comply with local and international privacy and security regulations. This regulatory framework should include continuous training for medical and administrative staff on best security practices, as well as regular updates to intelligent systems to keep pace with emerging cyber threats. Enhancing transparency and awareness among patients and end-users is also an integral part of building digital trust. Enabling patients to understand how their data is used and providing insight into security measures increases their sense of safety and promotes interaction with intelligent systems. This, in turn, improves healthcare quality, as medical staff can make accurate and timely decisions based on reliable and secure data. In conclusion, digital trust is the backbone of smart healthcare, enabling institutions to deliver innovative and effective services, protecting patients from cyber risks, and promoting digital sustainability in the healthcare sector. Investment in cybersecurity infrastructure, application of best practices, and user education remain essential factors for building a reliable and secure smart healthcare system.
