| Resum: | How can a buyer legitimately benefit from group discounts while preserving his privacy? We show how this can be achieved when buyers can use their own computing device (e.g. smartphone or computer) to perform a purchase. Specifically, we present a protocol for privacy-preserving group discounts. The protocol allows a group of buyers to prove how many they are without disclosing their identities. Coupled with an anonymous payment system, this allows group discounts to be compatible with buyer privacy. |
