The eHealth record is a sensitive information need to protect from an unauthorized user. The privacy and security is the major issue in the eHealth record. These challenges will be overcome by a decentralized cloud. To Access the eHealth record from anywhere and at any time, the decentralized cloud is used to store the eHealth record which is generated by the medical institution and also by the individual. In proposed work, the technique which used is a temporal shadow. Each patient record is hashed with temporal shadow and the final aggregated hash value is stored it in the blockchain. Each file is authenticated by temporal hash signature. So the security of eHealth record is imporved with the help of temporal shadow and finally its stored in the blockchain. © BEIESP.
