METHOD FOR PREVENTING BANK CARD FRAUD, APPARATUS, COMPUTER DEVICE AND STORAGE MEDIUM

摘要

A method for preventing bank card fraud, an apparatus, a computer device and a storage medium. The method comprises: acquiring a transaction request, the transaction request comprising a user ID and current transaction information, and the current transaction information comprising current transaction location information and current transaction time (S10); acquiring, on the basis of the user ID, target transaction information that is closest to the current transaction time, the target transaction information comprising target transaction location information and target transaction time (S20); acquiring at least one driving route distance on the basis of the current transaction location information and the target transaction location information, and acquiring a transaction time difference on the basis of the current transaction time and the target transaction time (S30); acquiring a target speed value on the basis of the at least one driving route distance and the transaction time difference (S40); if the target speed value exceeds a preset speed critical value, freezing a user account that corresponds to the user ID (S50). The present solution freezes a corresponding user account when it is determined that the current transaction is one in which the bank card was fraudulently used, thereby guaranteeing bank card swiping security for users.
