Securable Personal Healthcare Record in Cloud Storage

Personal Health Records are now receiving more attention as a result of the expansion of cloud computing (PHR). The privacy and security of patients' medical records must be protected even while e-health systems have the potential to enhance patient care. A number of cryptographic techniques, including encryption and distributed data processing, have been proposed to safeguard the security of private health information. But, because each recipient needs a different decryption key, sharing encrypted material with many parties becomes difficult. Due to the fact that the decryption private key can only be given to one individual, even (t, n) threshold privacy-preserving techniques have their restrictions. Our suggested solution offers a decentralized identity-based approach to decryption that makes it simple to open encrypted data without needing to create new secret keys. Using attacks on adaptively generated cypher text, we further show that our distributed identity-based decryption technique is private. To further ensure privacy protection without the requirement for private key regeneration, we add a (t, n) threshold to our distributed decryption system. With the goal of protecting privacy and secrecy, our solution handles the issue of sharing encrypted personal health information with several parties.
