The embodiments of this specification provide a method and device for identifying abnormal transaction behavior, wherein the method includes: presetting an abnormality recognition module and a scene recognition module for a business, wherein the abnormality recognition module and the scene recognition module have respective weights, The abnormality identification module is used to identify the abnormality of the transaction behavior in the business, and the scene identification module is used to identify the reliability of the business in the scene where the transaction behavior is located; using the The abnormality recognition module and the scene recognition module identify the transaction behavior in the business, and obtain the recognition results respectively output by the abnormality recognition module and the scene recognition module; use the abnormality recognition module and the scene recognition module respectively The weights of the abnormality recognition module and the scene recognition module are respectively outputted by weighted calculation to obtain the abnormal value of the transaction behavior.
Description
technical field [0001] The embodiments of this specification relate to the field of computer technology, and in particular, to a method for identifying abnormal transaction behaviors. One or more embodiments of this specification also relate to an apparatus for identifying abnormal transaction behavior, a computing device, and a computer-readable storage medium. Background technique [0002] With the development of Internet technology, transactions through the Internet have become a common behavior of Internet users. However, while online transactions bring convenience to users, there are also certain risks. In order to avoid the harm caused by the behavior of these criminals, it is necessary to identify the abnormal transaction behavior. [0003] However, at present, there are many misidentifications in the identification of abnormal transaction behaviors, which leads to the relatively limited application of business. SUMMARY OF THE INVENTION [0004] In view of this, ...
