Double Blind Comparisons using Groups with Infeasible Inversion

  title={Double Blind Comparisons using Groups with Infeasible Inversion},
  author={William R. Lorimer},
Double Blind Comparison is a new cryptographic primitive that allows a user who is in possession of a ciphertext to determine if the corresponding plaintext is identical to the plaintext for a different ciphertext held by a different user, but only if both users co-operate.
