In the delivery of high-quality healthcare services, the exchange of computerized clinical data holds significant importance. To safeguard the confidentiality of client's sensitive information, it is imperative to adhere to stringent privacy and security regulations when sharing this data with others. Consequently, the adoption of proxy re-encryption servers serves as an effective and reliable means of transmitting computerized medical information. This encryption method is currently recognized as the sole approach that is both unidirectional and recursive, allowing third parties to modify encrypted ciphertext intended for one party so that it can be deciphered by another. This technique is referred to as proxy re-encryption. In order to empower patients with control over who can access their healthcare data, the system operates as an intermediary between them and a database server. Prior to transferring files to the information server, individuals who own them can utilize their keys to encrypt the files, thus ensuring the security of the data stored there. The test results demonstrate the system's proficiency in supporting secure data sharing. These proxy re-encryption mechanisms guarantee the confidentiality and accessibility of data, offering end-to-end security and privacy for electronically stored health information. While prioritizing patient privacy, the system aims to enhance collaboration among providers and facilitates data sharing between the sender and receiver using their respective keys. In this context, a unidirectional system operates in a one-way, providing a higher level of security, making it a suitable choice for untrusted environments where message transport is necessary without granting the receiver rights to respond to it.
