Fast Private License Plate Matching Using Symmetric Homomorphic Encryption
Harshul Vaishnav, Anish Mathuria · 2018
Privacy-preserving license plate matching is a special case of private set intersection where the intersection result is known to only one entity. Most of the existing private license plate matching protocols rely on public key based homomorphic encryption. We propose a fast protocol for computing Hamming distance between license plates privately using symmetric homomorphic encryption. We practically analyse and compare the performance of our protocol with previous protocols which use Paillier cryptosystem.
