Blockchain technology can address issues of data integrity and security in the healthcare industry by providing a decentralized and secure way to store and manage patient data. By using blockchain, healthcare providers can ensure that patient records are tamper-proof and easily auditable, thus preventing unauthorized access or modifications. Additionally, the use of blockchain can help streamline data sharing between healthcare providers while maintaining patient privacy and confidentiality. This technology can also enable patients to have more control over their own data and consent to who can access it, improving overall data security in the healthcare industry.
