Embodiment 1

[0029] figure 1 The flowchart of the method for preventing bank card fraud in this embodiment is shown. This method of preventing bank card fraud is applied when a user uses a bank card to conduct a transaction. It calculates whether the current transaction information belongs to the security range of card swiping by checking the current transaction information and historical transaction information closest to the current transaction. , The bank card account will be frozen to protect the user’s bank card swipe security. Such as figure 1 As shown, the method for preventing bank card fraud includes the following steps:

[0030] S10: Obtain a transaction request, the transaction request includes the user ID and current transaction information, and the current transaction information includes current transaction location information and current transaction time.

[0031] Specifically, the server obtains the transaction request sent by the transaction terminal, that is, the user sends ...

Embodiment 2

[0085] Image 6 Shows the principle block diagram of the device for preventing bank card theft in one-to-one correspondence with the method for preventing bank card theft in Embodiment 1. Such as Image 6 As shown, the device for preventing bank card fraud includes a transaction request acquisition module 10, a target transaction information acquisition module 20, a distance and time parameter acquisition module 30, a target speed value acquisition module 40, and a security operation module 50. Among them, the implementation functions of the transaction request acquisition module 10, the target transaction information acquisition module 20, the distance and time parameter acquisition module 30, the target speed value acquisition module 40, and the safe operation module 50 correspond to the method for preventing bank card fraud in the embodiment The steps are one-to-one correspondence, in order to avoid repetition, this embodiment will not describe them one by one.

Embodiment 3

[0107] This embodiment provides a computer-readable storage medium with a computer program stored on the computer-readable storage medium. When the computer program is executed by a processor, the method for preventing bank card fraud in Embodiment 1 is implemented. To avoid repetition, it is not here. Repeat it again. Alternatively, when the computer program is executed by the processor, the function of each module / unit in the device for preventing bank card theft in the second embodiment is realized. In order to avoid repetition, it will not be repeated here.

[0108] Understandably, the computer-readable storage medium may include: any entity or device capable of carrying the computer program code, recording medium, U disk, mobile hard disk, magnetic disk, optical disk, computer memory, read-only memory (ROM, Read-Only Memory), Random Access Memory (RAM, Random Access Memory), electric carrier signal and telecommunication signal, etc.

Abstract

The invention discloses a bank card fraud preventing method and device, computer equipment and a storage medium. The bank card fraud preventing method comprises that a transaction request including auser ID and present transaction information is obtained, and the present transaction information comprises present transaction position information and present transaction time; target transaction information, including target transaction position information and target transaction time, closest to the present transaction time is obtained on the basis of the user ID; at least one driving path distance is obtained on the basis of the present transaction position information and the target transaction position information, and transaction time difference is obtained on the basis of the present transaction time and the target transaction time; a target speed value is obtained on the basis of the at least one driving path distance and the transaction time difference; and if the target speed value exceeds a preset speed critical value, a user account corresponding to the user ID is frozen. When a present transaction belong to bank card fraud, the corresponding user account is frozen, and the safety in using a bank card of a user is ensured.

Description

Technical field [0001] The present invention relates to the field of bank card security, in particular to a method, device, computer equipment and storage medium for preventing bank card fraud. Background technique [0002] With the development of bank card business, credit card consumption has been accepted by more people. Cases of bank card theft are not uncommon. Especially in the data age, all kinds of user information are stored in the big data platform. User information may be obtained by criminals due to Chinese Trojan horses, phishing, or card copying. Willing transaction behaviors cause financial losses to users. The current anti-theft brushing measures are mainly through the setting of rule engines, black and white lists, and transaction frequency rules on the big data platform. The setting of these rules does not restrict the increasingly mature fraudulent brushing technology, and the user's bank card still exists The risk of fraud, assets are not safe enough. Summ...
