Abstract: The wide distribution of clues, the large span of damage, and the large number of victims in telecommunication network fraud cases make it difficult to detect. Big data, artificial intelligence and other technologies have promoted precise investigations, but improper use of technology will also bring risks of personal privacy leakage and fraudulent use. This paper explores the anti-fraud collaborative governance of telecommunications networks based on blockchain, analyzes core capabilities and anti-fraud crowds, and uses blockchain smart contracts and cryptographic consensus to guarantee that the telecommunications data can not be tampered with and safe sharing. Finally, this paper carries out the logical design of anti-fraud collaborative governance to provide ideas for further landing applications.

Key words: artificial intelligence, anti-fraud in telecommunication networks, blockchain, collaborative governance
