Abstract

The blockchain-powered scheme for sharing medical files in a practical manner decentralized quality-based encryption is a secure and efficient approach for sharing sensitive medical information among healthcare providers. The system utilizes blockchain technology to store and handle the framework for restricting entry to specific areas and permissions for medical files, providing a tamper-proof and transparent mechanism for managing access to the data. Additionally, the use of decentralized attributes- based encryption ensures that patient data remains confidential and only accessible to those with the appropriate permissions. The scheme enables data owners to define granular access control policies based on specific attributes such as the type of data, patient information, and the role of the requesting party, enabling better collaboration and decision-making while ensuring data privacy and confidentiality.

基于区块链的安全高效的多云医疗文件共享
区块链驱动的方案以实用的方式共享医疗文件,分散的基于质量的加密是在医疗保健提供者之间共享敏感医疗信息的一种安全有效的方法。该系统利用区块链技术存储和处理限制医疗文件进入特定区域和权限的框架,为管理数据访问提供了防篡改和透明的机制。此外,使用分散的基于属性的加密确保患者数据保持机密,只有具有适当权限的人才能访问。该方案使数据所有者能够根据特定属性(如数据类型、患者信息和请求方的角色)定义粒度访问控制策略,从而在确保数据隐私和机密性的同时实现更好的协作和决策。
