Sensitive information patrol method using asynchronous sequence

The invention provides a sensitive information patrol method using an asynchronous sequence, which comprises the following steps: a first part, a postmortem sensitive information screening method: continuously obtaining target website data, and carrying out sensitive information preliminary screening on the target website data through a self-accumulated sensitive database; information meeting requirements in the preliminary screening result is extracted, and fine screening is carried out through a text classification algorithm; based on the hit sensitive information, classifying the sensitive degree of the fine screening result, and completing real-time pushing of the sensitive information; a second part, according to the beforehand sensitive information early warning method, an asynchronous sequence behavior database is constructed according to a timestamp and a sensitive degree type of the sensitive information published by a target website; and an asynchronous sequence point process model is constructed an
