Abstract
Electronic Health Record (EHR) systems have revolutionized the healthcare industry by enabling the efficient storage, retrieval, and sharing of patient health information. However, the widespread adoption of EHR systems has also engendered a myriad of privacy and security challenges that must be spoke to guarantee the privacy, integrity, and accessibility of sensitive patient evidence. A range of countermeasures has been implemented to reduce the risks associated with EHR data privacy and security. These include contact switch tools that limit data access to approved operators, as well as advanced encryption methods like Identity-Based Encryption and Attribute-Based Encryption, specifically tailored for securing EHR data in cloud environments. By employing these protective measures, healthcare providers can enhance the safety of sensitive patient information while adapting to the dynamic digital landscape.
