Abstract

A method for detecting false card risk comprises the following steps: a receiving step (S201), a transaction processing system receiving from a transaction terminal the data associated with the transaction which a financial IC card requests to process; an abnormity judgment step (S202), the transaction processing system judging whether the transaction processed under the request is abnormal according to the data; a false card risk determination step (S204), the transaction processing system determining that the false card risk exists on the financial IC card if the financial IC card abnormal number is greater than a first threshold or the frequency of the transaction which the financial IC card requests to process is greater than a second threshold. The method can find false card risk timely and improve the probability and efficiency of the identification of a false card. A transaction processing system is also disclosed.

Description

technical field [0001] The invention relates to computer technology, in particular to a method for monitoring the risk of counterfeit cards and a transaction processing system for realizing the method. Background technique [0002] With the popularization of financial IC cards, the cases of stealing cardholder funds by counterfeiting cards are increasing day by day. Such cases not only cause losses to cardholders, but also often lead to legal and economic disputes between card issuers and cardholders. Therefore the importance of how to technically guard against counterfeit financial IC cards becomes more prominent. [0003] At present, there are generally two methods for judging the authenticity of financial IC cards, that is, offline data authentication of the transaction terminal and online authentication of the issuing bank. In the former method, the transaction terminal will locally authenticate the card offline, and if the user's authentication information (such as pa...
