Homomorphic encryption

Definition

Homomorphic encryption is a form of encryption that allows computations to be performed on ciphertexts, generating an encrypted result that, when decrypted, matches the result of operations performed on the plaintext. This unique property is particularly important in personalized medicine, as it enables sensitive medical data to be processed without revealing the actual data itself, thus maintaining patient privacy and security.
