  • Privacy-preserving measurements of a campaign
    Patent number: 9641332
    Abstract: A method of measuring a campaign performance includes transforming identifiers into non-identifiers, and providing the non-identifiers to an external processing party; receiving encrypted non-identifiers comprising the non-identifiers after encryption by the external processing party, other non-identifiers, spending values, and a public cryptographic key, each member of the other non-identifiers being associated with a corresponding member of the spending values; encrypting the non-identifiers to generate other encrypted non-identifiers, and determining an intersection of the encrypted non-identifiers and the other encrypted non-identifiers to generate common encrypted non-identifiers; identifying a subset of the spending values associated with members of the encrypted non-identifiers in the common encrypted non-identifiers; and deriving a total spending value based on the subset of the spending values.
