DATA FRAGMENT VERIFICATION METHOD, APPARATUS, COMPUTER DEVICE, AND READABLE STORAGE MEDIUM

The present application relates to the technical field of cloud services, and discloses a data fragment verification method, apparatus, computer device, and readable storage medium, comprising: obtaining user data and service data; executing a sharding process to perform sharding on user data and service data to obtain user data and service data; executing parallel processes to obtain a user hash code and a service hash code having the same value, and user target data and service target data corresponding to the user hash code and service hash code; executing a verification process to verify the user target data and service target data so as to identify abnormal data. The present application not only improves the technical effect of data verification efficiency, but also avoids occupying the memory and computing power of centralized servers, thus avoiding the problem that a current user terminal cannot invoke other information in a database of a centralized server during the execution of a comparison operatio
