for example?

• yorwba 9y ago
  For example when two parties are interested in making a deal, but don't want to reveal it unless the other party is interested as well. (The example is usually a date, but it could be applicable to voting or other situations where both privacy and unanimity are desired.) By performing a homomorphically encrypted computation, they can set it up to only reveal the final decision, but not the individual inputs that determined it, so nobody loses face.
