Homomorphic Hashing

Definition ∞ Homomorphic hashing is a cryptographic technique where operations on data correspond to operations on their hash values. This specialized hashing allows computations to be performed directly on the hash outputs, yielding a new hash that corresponds to the result of the same operation on the original, unhashed data. It preserves certain mathematical properties of the input within the hash. This capability enables data processing without exposing the underlying information.
Context ∞ Homomorphic hashing is a subject of research interest in privacy-preserving blockchain technologies and secure computation. Its potential application includes verifiable computation where a third party can confirm the integrity of data processing without viewing the actual data. While not yet widely deployed in mainstream digital asset protocols, advancements in this area could significantly enhance data privacy and security within decentralized systems.
