Abstract

Addressing issues of collusion attacks, background knowledge attacks, and user cooperation willingness in existing user collaboration algorithms, a user collaboration privacy protection algorithm (Vss-scppa, Privacy protection algorithm based on verifiable secret sharing and smart contracts) has been proposed based on verifiable secret sharing and smart contracts. The algorithm first encrypts and splits user query information using a verifiable secret sharing algorithm and provides coefficient commitments to verify the integrity of sub-secret data. Next, it combines smart contracts and differential privacy technology to design a user selection algorithm, constructing an anonymous set. The algorithm’s effectiveness in resisting collusion attacks was analyzed. Experiments on the Geolife and BerlinMOD datasets show that the Vss-scppa algorithm offers higher privacy protection. Compared to Tr-privacy, Ik-anonymity, and Gcs algorithms, the efficiency of Vss-scppa increased by approximately 86.34%, 99.27%, and 99.19%, respectively. Vss-scppa significantly enhances algorithm efficiency while improving privacy protection, demonstrating its effectiveness in user collaboration privacy protection.
