Pricing agreements at AWS define how customers are billed for usage of services and resources. A pricing agreement consists of a complex sequence of terms that can include free tiers, savings plans, credits, volume discounts, and other similar features. To ensure that pricing agreements reflect the customers’ intentions, we employ a protocol that runs a set of validations that check all pricing agreements for irregularities.

Since pricing agreements are sensitive, we want to limit the amount of information available to actors involved in the validation protocol. Actors who repair validation errors should not be able to obtain information that is not necessary for the repair. Personal information for individual customers should remain private, and we also want to hide statistical properties of the set of pricing agreements, such as the average number of credits awarded to customers.

We introduce Parrot, a protocol for validation of pricing agreements that prevents information leakage. Parrot involves three categories of actors: the auditor who writes a query to check a validity condition, the fixers who repair anonymized invalid pricing agreements, and the owners who have permission to view non-anonymized pricing agreements. The protocol includes safeguards to prohibit parties other than the owners from learning sensitive information about individual customers or statistical properties of the full set of pricing agreements.
