The digitization of healthcare information has expanded access to medical data while raising concerns about its security, authenticity, and trustworthiness. This paper explores the role of digital certificates in addressing these challenges, focusing on their potential to verify the credibility of health information and protect sensitive data. It begins with a theoretical overview, emphasizing the importance of certificates in ensuring data authenticity and integrity, particularly in compliance with regulations such as the GDPR.The analysis examines current certificate models like HONcode and PIF TICK, highlighting their limitations in public awareness and practical application. Innovative technologies such as blockchain and zero-knowledge proofs are identified as promising tools for enhancing the security and traceability of health information. Blockchain’s immutability and decentralized verification capabilities, combined with patient-controlled data access via smart contracts, underscore its potential in fostering trust and compliance with privacy standards.The paper outlines essential certification requirements, including technical efficiency through machine learning, content accuracy based on scientific validation, and process transparency. Furthermore, user-centric approaches are emphasized to enhance certificate accessibility and public trust. The study also examines parallels in other industries, such as food and finance, which employ rigorous certification systems for safety and reliability.Ultimately, this research advocates for a hybrid certification model combining automated and expert-driven processes. By leveraging modern technologies and interdisciplinary practices, such a model can address the dual goals of ensuring high-quality health information and fostering user trust in the digital healthcare landscape.
