Fuente: Wipo "BigData" The invention relates to the technical field of information security, in particular to an auditing method and device for a big data platform algorithm. The auditing method for the big data platform algorithm comprises the following steps: reading big data platform data to obtain platform algorithm data; according to the algorithm platform data, performing model construction through a preset supervision sandbox to obtain a platform algorithm model; reviewing the platform algorithm model in a preset supervision sandbox to obtain a reviewed algorithm model; providing test data by a preset supervision sandbox, and testing the examined algorithm model by using the test data to obtain a test result; and obtaining a platform algorithm auditing result according to a test result. The method is a stable and effective big data platform algorithm auditing method.
