AI Technical Summary
Existing technologies cannot effectively protect user privacy when identifying influential disseminators in social networks, especially when network information is distributed and some views contain private information. Traditional algorithms require a complete network graph and are therefore unsuitable.
By employing blockchain technology combined with a decentralized secure multi-party computation protocol, the disseminator can be identified without knowledge of the overall structure of the social network through encryption and decryption methods, and the Lifted ElGamal threshold decryption system is used for data protection.
It enables the accurate identification of influential disseminators in social networks, prevents collusive attacks, and ensures the security of raw data while protecting user privacy.
