US Patent 11418525 Data processing method, device and storage medium

A type identification is firstly performed on a to-be-processed access request, and when the to-be-processed access request is identified as a first-type access request, anomaly identification is then performed on the to-be-processed access request by using a machine learning model. The techniques of the present disclosure not only accurately identify an abnormal access request, but also effectively reduce the number of access requests that need to be identified by the machine learning model, thus saving computing resources of the device and improving the operating performance of the device.
