Detailed explanation-1: -Homomorphic encryption allows encrypted data to be processed while it is still in an encrypted state. If data is encrypted by any other means it must first be decrypted before processing, and this renders it vulnerable to unauthorised access.
Detailed explanation-2: -Homomorphic encryption is the conversion of data into ciphertext that can be analyzed and worked with as if it were still in its original form. Homomorphic encryption enables complex mathematical operations to be performed on encrypted data without compromising the encryption.
Detailed explanation-3: -One such application is Private Information Retrieval (PIR). Private Information retrieval is a protocol whereby a user can retrieve an item from a database without revealing which item is retrieved.
Detailed explanation-4: -Use case: Secure data governance Homomorphic encryption could be used to allow organizations to securely store, process, and exchange sensitive data, while also ensuring compliance with data governance regulations, such as in the case of customer data or personal data.
