LinkedIn's Revenue Attribution Report (RAR) has enhanced privacy and reduced network congestion by over 99% through the implementation of additive symmetric homomorphic encryption (ASHE). This new system enables secure queries on encrypted data without the need for row-level decryption, improving performance and maintaining robust privacy guardrails. As a result, advertisers can better measure the impact of their marketing campaigns while ensuring member data protection.
