How is the anti-fraud warning triggered?

Ordinary people trigger early warning when they receive telecommunication network fraud.

Anti-fraud early warning is a process in which the anti-fraud early warning system automatically analyzes and finds potential victims by using big data, artificial intelligence and other technologies according to the numbers involved provided by the public security organs, and sends early warning short messages to users at the first time through the 1238 1 short message port.

Specifically, when ordinary people receive fraudulent calls from telecommunication networks, they will trigger an anti-fraud early warning system, and the system will judge whether users are at risk of being cheated according to the types, contents, frequency and other factors of fraudulent calls.
