The invention discloses a control method and device of a cancel-after-
verification system and a storage medium, and belongs to the technical field of cancel-after-
verification systems. The method comprises the steps that after an offline cancel-after-
verification action is triggered, a cancel-after-verification task is generated based on cancel-after-verification information and first cancel-after-verification card information in a local
database, the cancel-after-verification task is decomposed into at least two cancel-after-verification subtasks,
time sequence information of the cancel-after-verification subtasks is constructed based on
execution time corresponding to the cancel-after-verification subtasks, and after it is detected that a network is recovered, the cancel-after-verification task is executed. And based on the
time sequence information, executing a replay action of the cancel-after-verification task on the
cloud database so as to synchronize the first cancel-after-verification card information and second cancel-after-verification card information in the
cloud database. According to the method, the verification states of the local
database and the
cloud database are synchronized step by step according to the original
time sequence of the offline operation, so that the continuity of the verification service is ensured, the problem of state conflict or data inconsistency possibly caused by direct data coverage is avoided, and the reliability and user experience of the
verification system in a
complex network environment are improved.
